Fall/Winter 2019 • 57 ACPA COLORADO/WYOMING CHAPTER Angela Folkestad P.E. Pedaling the Plains to Celebrate Concrete Pavement Performance This year’s Pedal the Plains bicycle tour provided a great opportunity to visit southeast Colorado and explore the host communities of Lamar, Holly and Springfield while learning about the agricultural contributions of the region and visiting historical sites along the route. The three-day bicycle tour wrapped up with a ride on 45 miles of concrete pavement on US Highway 287 from Springfield to Lamar and included a visit to the concrete runway at the Springfield Airport that was paved 20 years ago and has a Pavement Condition Index (PCI) of 86. US 287 is a north-south route that enters Colorado at the border with Oklahoma and carries a high volume of trucks (45%-65% of all traffic). The Colorado DOT began overlaying this stretch of the Ports to Plains route with concrete pavement in the 1990s to reduce their maintenance and rehabilitation costs, and the strategy has paid off! The 2019 Pedal the Plains route gave cyclists an opportunity to ride on four different concrete pavement projects constructed along US 287 since 1999, and many commented on how smooth the ride was. On your next trip, use this guide to view the pavements in person. Springfield North (MP 28.5 – 40.6) • 10-inch concrete overlay of existing asphalt • 20 years of performance and counting • Completed in 1999 by James Cape & Sons North of SH 116 (MP 40.6 – 51.9) • 12-inch concrete overlay of existing asphalt • 12 years of performance and counting • Completed in 2007 by Interstate Highway Construction (IHC) Gobbler’s Knob (MP 51.9 - 60) • 8-inch concrete overlay of existing asphalt • 20 years of performance and counting • Completed in 1999 by Castle Rock Construction Company Lamar South (MP 60 - 73) • 11-inch concrete overlay of existing asphalt • 11 years of performance and counting • Completed in 2008 by Castle Rock Construction Company Count on Concrete Pavement for your next project and take advantage of the longevity it provides! Note: Pedal the Plains is sponsored by The Denver Post and the State of Colorado. The route and host communities change every year to provide riders an opportunity to explore Colorado’s high plains.
