Every year since 1916, on the last Sunday in June, America’s Mountain in Colorado, USA, Pikes Peak, is host to The Broadmoor Pikes Peak International Hill Climb (PPIHC), also known as The Race to the Clouds. This annual automobile and motorcycle hill climb to the summit of Pikes Peak is over 12 miles long, and this year they knew prior to the race, the final two-mile stretch was in need of repair.
Colorado Springs, CO
Owner: Pikes Peak Highway Toll Authority
Contractor: Kiewit Infrastructure
Completion Date: May 2018
Due to yearly water, thermal and traffic challenges, the client is forced to spend $250,000 - $300,000 per year to maintain Pikes Peak Highway. Due to major cracking and rutting, in the spring of 2018, major repairs were required on approximately two miles of the highway in order to make the road safe for the upcoming race.
Approximately two miles of Pikes Peak Highway was milled, patched and overlayed in order to make the road safe for the upcoming race. The client chose to use Fiber Reinforced Asphalt Pavement (FRAP), using ACE Fiber as the additive, for half of the project.
ACE Fiber will help the overlay last longer and keep cracking at bay until a complete reconstruction can occur in 2019. Kiewit’s Colorado Springs plant produced 196 tons of Ace Fiber FRAP, followed by their crew installing it on the highway.
The biggest installation challenge was elevation. The site was 13,500’ to 14,000’ above sea level and the temperatures were pretty low. Morning frost was common and the temperature highs were approximately 50 degrees Fahrenheit (10 degrees Celsius). Paving took place over two days, with a standard crew, one day of which was with ACE Fiber, and round trip truck time to the plant was four hours.
ACE Fiber was introduced into the asphalt at the plant using a hand dosing machine and a certified mixing technician from Nilex, who ended up working with and certifying the Plant Superintendent at Kiewit, thus allowing the issuance of a certified mixing report and allowing Kiewit to be certified for future ACE Fiber projects.
Due to the impending race, time constraints were a concern for this project, therefore by using ACE Fiber the project was completed much faster than it would have with an interlayer. Nilex’s ACE Fiber was also a competitive price and stayed within the client’s budget. Nilex provided onsite support at the plant during the dosing of ACE Fiber into the asphalt. The race went off without a hitch, in fact, the race produced an all-time speed record with Romain Dumas setting a new record, over 15 seconds faster than the previous record, and the clients are happy with the end product.
