Colorado Public Works Journal, Spring-Summer 2021

Castle Rock Construction was awarded the US 287 Campo passing lanes project and started work in mid-March of 2020. US 287 is a major trucking route, and this segment in southeastern Colorado is part of the Ports to Plains route that stretches from Canada to Mexico. The work consisted of removal of existing concrete shoulder (7,700 SY), and the addition of two new passing lanes (32,250 SY), both approximately 1 mile in length. The new lanes required a full depth reclamation with a 12" base and 11” of concrete pavement to accommodate the heavy truck traffic. Paving was performed during the month of August, causing many potential challenges related to hot, dry weather. CRCC coordi- nated with CDOT to ensure proper concrete temperatures were maintained while adhering to all CDOT specifications. With this project being a large distance from any urban area, planning and budget were especially critical, and cost-efficient ideas needed to be implemented. CRCC used the panels that were removed from the shoulder and recycled them back into the aggregate base and into the concrete mix. CRCC also adjusted the paving schedule to optimize the time onsite and prevent multiple mobilizations. Roadway smoothness is a high priority for CRCC, and they were able to pave both passing lanes with a very low IRI. Only one area in the entire project needed grinding to meet smoothness criteria. Even will all the hurdles the project was f inished ahead of schedule in early October of 2020. The project adhered to COVID- 19 regulations and prioritized the safety of the workers and the traveling public. 2021 Excellence in Concrete Pavement Awards 28 | Colorado Public Works Journal Owner: CDOT Region 2 – Lamar Residency Contractor: Castle Rock Construction Company Construction Management: CDOT Region 2 – Lamar Residency US 287 Passing Lanes near Campo, CO CATEGORY: State Roads
