JCB has developed a highly productive single-machine pothole and patching repair solution to fix potholes permanently, the first time, without the need for labor intensive repair methods or additional expensive machinery. The Pothole Pro can repair a pothole in less than eight minutes - four times quicker than standard methods and at half the cost of current solutions. The machine’s development has been personally led by JCB Chairman Lord Bamford. JCB Pothole Pro Delivers Rapid Permanent Repair Solution “Potholes are really a scourge; we are fixated on this dreadful problem and I am fixated on finding a solution. We simply cannot allow our road networks to continue to be blighted by potholes,” says Lord Bamford, JCB Chairman. “JCB’s solution is simple and cost effective and fixes potholes permanently, first time. Once the machine has done its job all the contractor then needs to do is just add asphalt.” Tests with contractors and municipalities show the JCB Pothole Pro can complete a pothole repair in less than eight minutes – equivalent to 700 potholes per month. With a 25mph travel speed, the machine can rapidly relocate between sites without additional transport costs. The JCB Pothole Pro is equipped with a planer, with mounted on the machine’s rear skid steer hitch. The planer is 24 in. wide, with up to 4.26 ft. of side-shift adjustment. This allows the operator to plane a full roadway lane from the curb, without repositioning the machine. Hydraulic tilt and depth control provide a consistent depth for larger patches.

FALL/WINTER 2023┃7 In the future, the eastbound and westbound lanes of the A 43 Autobahn near the city of Münster, Germany, will be separated by a poured in-place concrete safety barrier. The effectiveness and permanence of such construction elements for the passive protection of road users makes them the preferred vehicle restraint system, especially on sections of roads with heavy traffic. The monolithic profile was paved by an SP 25i using the slipform paving method. The use of AutoPilot 2.0 on this project eliminated the need for the paving crew from VSB infra GmbH & Co. KG to set up a stringline for controlling the machine. The automatic 3D control system optimises paving workflows Developed by Wirtgen, the control system enables precise, stringless control of slipform pavers. It consists of a control system integrated in the machine, a base station and a tablet computer that can be used together with the Field Rover survey pole and on the slipform paver. As the system completely eliminates the time and effort usually required for setting up and removing a stringline for conventional machine control, it also reduces the associated project times and costs. Instead of this, the machine is guided along a virtual stringline by satellite-aided navigation. This makes the entire workflow faster, more efficient and, in turn, more cost-efficient. At the same time, it makes the paving of complex geometries such as tight radii or S-bends much easier. ‘This is another project on which we are using stringless paving. We have been using the AutoPilot system since it came onto the market. It saves us so much time that we use it on both of our machines whenever we can.’ says Kay Petersen, CEO of VSB infra GmbH & Co. KG. More working space and on-site safety As is typical for construction projects on major highways like the A 43 Autobahn, the working area offers very little room for the paving crew. Using a stringline in front of the machine in situations like this would limit this space even more. But you won’t find one here, however hard you look! Not unless you take a look at what’s shown on the screen of the AutoPilot tablet. The hand-held control unit displays the course of the virtual stringline and provides precise information to the machine operator at every single point along the predefined track. This also means that there is plenty of free space in front of the slipform paver. Concrete mixers have room to manoeuvre and can drive right up to the paver to deliver their load. The free space in front of the machine brings the paving crew more room to work in and leads to greater safety on the project site. The absence of a stringline also removes the risk of tripping and injuries as a result of falls.

10┃ Colorado Public Works Journal Recent reports continue to highlight America’s growing problems with substance misuse. Data from the 2021 National Survey on Drug Use and Health (NSDUH) reveals 16.5% of the U.S. population aged 12 and older meet criteria for having a substance use disorder (SUD), including alcohol and/or drug use. This amounts to over 46 million individuals in our communities, workplaces, and families. Yet less than 10% of affected individuals seek help; and far fewer receive help for SUD. Why? Traditional methods do not work because of the extreme stigma associated with SUD. This includes perceived and actual judgement of others AND shame from self-stigma by those who need support but are embarrassed or fearful to ask for help. The workplace can provide a safety net for employees struggling with substance misuse and/or suffering in silence. Employee Assistance Programs (EAPs) and behavioral health services embedded in group health benefit plans can provide a path for early intervention. The National Safety Council reports employers spend an average of $8,817 annually on each employee with an untreated SUD. However, hiring employees in long-term recovery positively impacts your workplace: • every employee who recovers from a substance use disorder saves a company over $8,500 on average • workers in recovery are strong employees who experience lower turnover rates, higher productivity, lower healthcare utilization and costs, and decreased absenteeism. • workers in recovery miss 13.7 fewer days each year than workers with an untreated SUD and 3.6 less days than an average employee. Recovery-Friendly Workplaces Reduce Stigma and Remove Other Barriers A promising development that is helping employers to reduce stigma and empower employees to see help is the RecoveryFriendly Workplace movement (also known as Recovery-Ready Workplaces). This movement began in New Hampshire in 2018 to increase employment for those in long term recovery who faced discrimination and barriers to employment. The Health Links® program in Colorado has become a national leader for Recovery Friendly Workplaces. Health Links® is affiliated with the Colorado School of Public Health, Work and Environment. Hallmarks for Recovery-Friendly Workplaces • Stigma reduction - by normalizing the conversation on SUD, empathy and understanding can replace judgment and shame • Acceptance and affirmation of everyone in the workplace creates a sense of belonging which promotes collaboration and teamwork • Flexible policies pertaining to leave and time off to attend recovery meetings and/or physical and mental health care • Peer to peer support and mentoring • Onsite recovery meetings • Ongoing training, resources, and support Action Steps for Employers 1. Undertake a reality check—does your senior leadership team understand the human and financial impact of substance misuse and substance use disorder on your organization? 2. Galvanize leadership commitment – encourage leaders to be visible, vocal, and vulnerable by sharing leverage lived experience stories to reduce stigma and remove barriers to employment 3. Evaluate and share resources, including the Employee Assistance Program (EAP), governmental and non-profit social service organizations, as well as 12-step recovery programs. 4. Train managers and first-line supervisors – Building and aligning a cultural framework for recovery-friendly workplace requires that all people managers and first-line supervisors understand the challenges of SUD and the benefits of becoming a recovery-friendly workplace. 5. Educate employees – focus on reducing stigma and promoting active care-seeking for substance misuse with an emphasis on preserving recovery capital, the resources needed for a person to get the help they need. 6. Tap existing resources – employers are encouraged to join forces with state and/or local initiatives. Recovery-Friendly Workplaces Reduce Stigma By Cal Beyer

14┃ Colorado Public Works Journal Growing populations in the Colorado Front Range have started to create unique challenges for many public works departments. Among these many challenges is the need to replace aging or undersized infrastructure within the urbanized area. The City of Westminster recently completed a substantial project that exemplifies the value of creative thinking, collaboration and strategy in replacing or upgrading infrastructure in the urban corridor. Improvements to Westminster’s Big Dry Creek sanitary sewer interceptor were critical for allowing the city to move forward with planned development, while also providing sustainable and resilient sewer service to Westminster residents. The $32 Millon project was incredibly successful but had plenty of challenges to overcome on the way to success. The Problem The city’s Big Dry Creek Wastewater Treatment Facility (BDCWWTF) is the primary facility for treating wastewater in Westminster. Two-thirds of the city’s wastewater is delivered to this facility using the Big Dry Creek sanitary sewer interceptor system, with the remaining 1/3 treated at Metro Water Recovery. The interceptor runs from Standley Lake near 100th and Wadsworth to near 128th and Huron. When the line was originally installed, much of the area was undeveloped, and construction through the area was much less complicated. Today, most of the line weaves through neighborhoods and across busy roads. It also crosses through designated open space that is crisscrossed with utility infrastructure. The most challenging of the infrastructure to work around – the raw water supply line for the cities of Northglenn and Thornton. This is the problem that offered the greatest opportunity for collaboration, innovation and unique problem solving. City of Westminster – Big Dry Creek Sanitary Sewer Interceptor Rehabilitation Tamara Moon The Players Westminster was not alone in the development and implementation of the Big Dry Creek sanitary sewer interceptor rehabilitation project. The project was truly a collaborative, multi-agency effort. Design of the project was done by HDR, Inc. HDR’s team was also tasked with assisting Westminster in developing a strong communications plan. The plan developed by HDR established strong lines of communication and education for the public. Project Manager, Rudy Archuleta said, “HDR’s public information plan had a substantial impact to the success of the project. The plan kept communication with the public at the staff level, reducing the need to escalate concern to city management and keep the project moving forward.” The design for rehabilitation developed by HDR was put into action by T. Lowell Construction, Inc (T.Lowell) and C&L Water Solutions (C&L). T.Lowell was the contractor selected to perform the open cut construction, largely through Westminster’s City Park.

FALL/WINTER 2023┃15 T.Lowell is an industry leader in pipeline construction. Their team, while well-respected as quality contractors, gained further accolades by being flexible and collaborative in the construction implementation timeline. C&L installed the trenchless cured-in-place pipe (CIPP) throughout the remaining portion of the system not previously lined within the last 10 years. C&L successfully navigated dense urban areas and complicated open space access challenges while installing the CIPP. C&L met these challenges and delivered exceptionally. The staff at Westminster, HDR ,T. Lowell and C&L carried out the bulk of the project, however, the work impacting open space and other municipal utilities could not have been accomplished without staff from Northglenn and Thornton. Their open communication, support of the project, and flexibility allowed the project to move forward with minimal interruptions for a timely completion. Communication is the Key One aspect of the sewer line rehabilitation project that the City of Westminster and Rudy Archuleta are most proud of is the robust Public Information Plan that was developed by HDR, Inc. The public information plan was developed as part of the project design work. With such a large portion of the city potentially impacted by the project, Westminster and HDR recognized that to achieve success, communication with the public was essential. The plan developed by HDR utilized a holistic approach to communications. There was a strong consideration for providing communication to the community’s diverse demographics. The plan recommended creation of a unique email address for the project where concerns, questions and suggestions from the public could be gathered and addressed easily. This allowed city staff to quickly respond to the public without worrying about communications getting lost in someone’s inbox. Beside needing to communicate effectively with residents, Westminster and HDR needed a plan to communicate with trail users. The Big Dry Creek trail is a popular hardsurface trail used by commuters in the north area. Effectively communicating detours, particularly through Westminster City Park, was critical for maintaining commuter access throughout the project. For Westminster, developing a public information plan, that cost less than one percent of the overall project cost, offered an exceptional return on investment. When Worlds Collide During the design portion of the project, engineers from Westminster and HDR acknowledged that the open cut portion of the project, running through the Big Dry Creek Open Space would have a direct impact on a critical portion of water supply infrastructure for the neighboring communities of Northglenn and Thornton. As a nod to the idea of exceptional communication, staff from these two communities were involved early in the project, to provide input on constructability, safety and timing. For the municipal staff involved in this portion of the project, timing was the most critical aspect of construction. Plans originally had work through the open space, where the Northglenn-Thornton pipeline would be crossed five times, occurring in the summer. Through discussions and collaboration, it was determined that to protect the pipeline and provide a layer of safety for workers, crossings and relocation of the Northglenn-Thornton pipeline would occur during the winter. Adding an additional layer of challenge to working around the Northglenn-Thornton pipeline was the substantial excavation depths. With much of the trench work done at depths up to 30-feet, T. Lowell, and the three cities had to come up with innovative solutions for supporting a 48-inch concrete pipeline so that working conditions were safe and the risk of damage to the pipe was minimized. Unexpected Partners While discussing the project with Rudy Archuleta, he shared an aspect of the project that offered Westminster a unique opportunity to partner with an organization for the benefit of the larger community. A portion of the open-cut trench line replacement passed through property utilized by the Butterfly Pavilion. This facility is dedicated to educating the public about the smallest animals in the environment and their value in sustaining healthy ecosystems. Westminster staff and consultants recognized the value that working with the Butterfly Pavilion could bring to their project, but also to those visiting the pavilion and utilizing the surrounding trails. Input from Pavilion staff was implemented in the restoration work done on the site. There was a substantial emphasis on combining construction practices with good conservation practices around the Butterfly Pavilion. Activities to protect the surrounding ecosystems during and after construction included relocation of Prairie Dogs, reseeding disturbed soils with native plants, and a commitment to protecting pollinators by utilizing manual control methods of weed control. While collaborative activities are not always the most affordable from both the dollar and time standpoint, they highlight Westminster’s commitment to creating a better environment for the community. The Big Dry Creek interceptor project also highlighted the value to both Westminster and the larger community, when organizations come together and create innovative and sustainable solutions.

18┃ Colorado Public Works Journal Sunland Asphalt had the opportunity of a lifetime: pave the Formula 1 racetrack in Florida for the Miami Grand Prix. If you were a football player, this would be the Superbowl. But there was a long road ahead (no pun intended). Selection Process “Winning the project required a multi-step selection process that Sunland would have to navigate.” stated Construction Director, Immanuel Martinez. “This included an initial meeting with the Miami F1 Ownership team and their construction team to discuss Sunland’s experience in paving, specifically withy echelon racetracks. Final interviews included Sunland’s in-depth understanding of the project’s specifications, as well as answering more in-depth questions regarding staffing and equipment availability for construction, construction methodology, different technical scenarios, and crew/equipment capabilities.” Pre-Construction Planning “When it comes to pre-construction planning and coordination for a project of this magnitude, it is quite extensive. There is coordination for Sunland to get all their construction equipment and teams across the country, planning with the design and engineering teams, and coordination with the Hard Rock stadium, Miami Dolphins, and South Florida Motorsports,” said Immanuel Martinez. “The coordination began with the logistics of moving our teams and equipment from Arizona to southern Florida. Sunland partnered with our vendors RDO and Empire Caterpillar to source equipment that was needed from around the country: from Minnesota, Arizona, Tennessee, and surrounding areas. “Sunland also had to coordinate the logistics of flights, transportation, and hotels for our crews. In total, Sunland brought Chasing Millimeters in Miami: Every Paving Contractors Dream Getting the opportunity to construct a Formula 1 racetrack is the pinnacle for any paving contractor. There is no bigger stage when it comes to milling and paving. in over 40 pieces of heavy equipment on 35 different transport loads, 75 internal employees, and 15 technical specialists.” “Once our management team arrived on site, planning the coordination of the construction process commenced. This intricate process included working with the general contractor Moss, South Florida Motorsports, and the Miami Dolphins to plan our milling and paving process while minimizing our impact to the ongoing football schedule of the Miami Dolphins, the extensive bleacher and sit build-out process, and the paddock building expansion that was going to be ready for race day. Not only did Sunland have to coordinate around those obstacles, we also had understood that there are only certain areas on a racetrack where it is acceptable to have a transverse paving joint. This meant that starting points, ending points, and the amount of asphalt tons needed to be precise. In total, Sunland had 35 different iterations of phase maps detailing our paving phase options. The phasing ended up being divided into 6 different phases or days. Each day equated to approximately 1,200 tons.” Sub Selection “As is known within any kind of construction project, the selection of subcontractors is most important. They can often make or break a successful project, and it’s your name on the line. Sunland regularly has a very thorough and extensive sub selection process. We felt confident in that process. Knowing that this project would be on the largest stage for milling and paving in the world, while being held to the highest specifications with the tightest tolerances that leave little room for error, we chose to work with contractors that we worked with previously and helped us achieve this opportunity. These subcontractors were CMT, S3 Arizona, Sitetech, Topcon, AMS Technical Services, Western Technologies, Empire Machinery, and RDO Equipment.” Images: © Mark Taylor at Extreme Arial Productions

FALL/WINTER 2023┃19 Supply Chain Management “When analyzing the supply chain,” according to Construction Director, Immanuel Martinez, “many factors need to be considered. Some of the key items are transport needs, materials, equipment, manpower, and technology. Getting these items locked in early is key. We had equipment coming in from Arizona, Minnesota, Utah, and South Carolina. Having a clear understanding of transport needs and being able to contract with transporters from across the county proved to be challenging, but our management team was able to pull it together and make it happen.” Crew Selection “Paving a Formula 1 racetrack is different from any typical style roadway paving project when it comes to crew selection. On typical roadway construction we would have one crew handling the milling and one crew handling the paving. On this project we were running three milling spreads and three paving spreads in unison. Crews that were used to working independently had to come together to form a large milling crew and large paving crew that all operated as one cohesive team, and at an extremely high level. These crews also had to utilize their technical skills to meet the tightest smoothness, compaction, and uniformity specifications that are rarely required from them. Our crews came together as one large team and performed at the highest level completing the project without needing any rework, meeting all project specifications without hesitation.” Equipment Selection “Equipment selection was based on two factors: what was written in the original specifications and what was available. What we were not able to secure in our own market, we were able to lean heavily on several out-ofmarket dealers. Specifically, RDO Equipment and Empire Machines for key units like: Pavers, Rollers, and Material Transfer Vehicles. The use of rental equipment was also necessary to maintain certain types of equipment written into the original contract.” Construction Survey “With the circuit wrapping 3.3 miles around the Hard Rock Stadium (home of the Miam Dolphins), this proved challenging from the standpoint of line of sight which is crucial for UTS surveying. Our survey crews spent nearly 18 days prior to initial construction on pre-construction topos and carefully planned the layout and process for the construction crews.” Construction: Milling “Milling was specified at +/-2” with the use of the Universal Total Station (UTS) Machine Control. UTS is a high-accuracy dynamic tracking system that uses a laser to track a target on the mill and monitor and control drum elevations with 3D positioning precision. UTS is one of the highest accuracy grade control systems available today. Cleaning behind the milling proved to be a challenge. This was due to the lime rock that was used in the original paving. Our crews used vacuum trucks, power brooms, and blowers to achieve an extremely clean finished surface. Construction: Paving “Crews performed two test passes to help dial in the cohesiveness and material verification. Once the paving started, it was seamless. Feeding the three pavers in echelon were three MTVs for material consistency, as well as helping minimize heat segregating. Each paver was outfitted with Thermal Mapping Systems. Rollers utilized Intelligent Compaction for heat monitoring, pass mapping, and reporting.”

24┃ Colorado Public Works Journal WWW.CO-ASPHALT.COM LOCAL AGENCY NEWS KaPunk- KaPunk- KaThunk.....KaPunk- KaPunk- KaThunk What is that damn sound that is breaking into my childhood revelry? Revisiting the grand old street of my memories. Browning Avenue, where I rode my banana seat bike to my grade school so long ago… some punk kid in his amped up Corolla, throwing down the base no doubt? Damn annoying is what I would call it. It’s Sunday morning, in Manhattan, Kansas. People going to church or drinking coffee on the porch with the paper...Have some respect! This past week, I took a few extra days to drive Interstate 70 back to the “Little Apple” to see my mother. There are two months (May and October) when I truly enjoy this pilgrimage. When the weather is perfect and the landscapes are works of art. So it was out of sorts that I was so aggravated. What was it that was bothering me so? Then, like a ray of sun through the clouds, it came to me at mile marker 105, ...I drove onto smooth, wonderful, newly overlaid asphalt after the annoying KaPunk- KaPunk- KaThunk of a long stretch of concrete pavement. Hours of dodging chuckholes, spalled joints and nasty bridge decks had fried my nerves. Thank you concrete. Tom Knostman, P.E. Pavement Engineer, Street Department, Streets Maintenance Program (970) 818-1246 Browning Avenue is Dead! Long Live Browning Avenue! Failed Concrete Pavement Out, Replaced with Asphalt It is rare that I find a concrete pavement that makes it to its expected life span. But hats off to the Lil Apple cause, by golly, they are determined to get there. Browning Avenue is not the road of my memories, a handsome collector road built in the suburbs back in the 60’s when I was born. Browning is two lanes of 6-inch concrete with welded wire reinforcement that was going to go the distance despite the ride at the surface, KaPunk- KaPunk- KaThunk To their credit, the Streets Department had tried everything to salvage the ride, including full and partial-depth repairs, only to have that concrete fail. In the end, they did what all good road folks do...patch it with hot mix. 4┃ The Road Ahead

FALL/WINTER 2023┃25 WWW.CO-ASPHALT.COM CITY OF FORT COLLINS PAVEMENT MANAGEMENT So as a Pavement Engineer, how would I salvage this road? Rebuild the concrete and have the road down for three to four months at significant cost, or overlay it with asphalt and be back in service in a week. That choice is a no brainer and at a fraction of the cost and carbon release. At my job in Fort Collins, I had exactly this experience. What do you do when a concrete road fails early? West Drake Road had been widened and improved in 1996 with 8-inch plain, jointed (no steel) concrete. Curb with wide 5-foot gutter/bike lanes and medians dressed it out to the thinking of the time, but 20-years later we had spalling joints in the bike lanes and numerous failures at cross joints. We tried Fibercrete repairs in 2014 only to find that the concrete continued to degrade outside the patch, so in 2018, we got permission to close the road, one direction at a time, while we broke out and replaced (with steel) about 15 percent of the road based on engineering judgement. This effort was painful and expensive. We had to close down a directional lane on a 20k ADT road a month and a half per direction, three total months. OUCH! This effort cost us $800K for the half mile or 2.75 lane-miles of pavement, and we only repaired 15 percent of the surface. This is $300K per LM, three times the cost of a 3-inch asphalt inlay at the time. The sad part is that we will need to do it all again in the next four years to deal with a new crop of raveled joints and broken panels. We would have saved money ripping it out and replacing this pavement with asphalt in 2014. In contrast to this costly, ongoing repair debacle, the Fort Collins Streets Department took on a 2.5-inch mill and fill repair of the asphalt pavements on the same road directly to the east in 2023. This, half-mile stretch of composite asphalt was originally built in the early 1980’s and had been resurfaced in 2012 using hot-in-place recycling which returned about ten years of service. This modified, dense graded inlay effort was complete in FOUR working days, using local crews from Martin Marietta and Alpha Milling under a full closure. This quality outcome provides users with a fully resurfaced road, with an excellent ride that will provide 20-years of uninterrupted service with emphasis on milling through unbonded layers, cleaning and tacking the new lift to a sound foundation layer, a highquality dense graded SX HMA expertly compacted and placed with shingled joints to assure long joint quality. This effort was accomplished for a cost of $375K or $170k per lane-mile. A fraction of the cost of the concrete repair with almost no down-time and improving the ride of the entire surface! They say that you can never go home again, but sometimes it’s worth it to realize what you have. (The asphalt option was completed at …) a fraction of the cost of the concrete repair with almost no down-time and improving the ride of the entire surface! FALL 2023┃5
