Arkema-Road Science customer, Simon, a Colas company, Cheyenne, Wyoming, recently won three Colorado Asphalt Pavement Association “Best in Colorado” Asphalt Pavement Awards, two of which were for Smoothness Pavement Category II and Project Innovation for their work on State Highway (SH) 14. The project covered 9.1 miles of a two-lane state highway with an average annual daily traffic of 2,100 vehicles, approximately 40% of which is truck traffic from nearby agriculture and oil and gas operations.
Arkema-Road Science technical expert, Jeff Weitzel, worked with Simon on the project to apply our Strata reflective crack relief interlayer technology and provided his technical support onsite to ensure a successful outcome for the project. The fine reflective cracking interlayer (RCI) mix combined with the high strain-tolerant asphalt concrete contributed to the project’s overall smoothness.
Arkema-Road Science’s Strata technology facilitates the successful overlay of concrete pavements with hot mix asphalt (HMA). It is a specialized high strain-tolerant and finely graded HMA mixture typically applied through conventional paving equipment, followed by a typical HMA surface mixture. The Strata interlayer significantly delays reflective cracking keeping the entire pavement structure in good condition and the traveling public happy. Strata also prevents water from entering the pavement layers below the Strata lift and preserves the structural integrity of the pavement, lengthening the service life of the pavement.
Arkema-Road Science is grateful to have had the opportunity to work on this project and sends our congratulations to the Simon team on their success!
