A new Capital Pavement Preservation Program (CPPP) guides project selection for the structural rehabilitation of Mohave County, Arizona paved roads approaching end of service life. The Program's innovative qualities lie in the technical basis of CPPP development, which employ practical and proven engineering methods to compute a new, singular measure of pavement structural stability using readily available County road asset data and nationally published soils data. It constitutes the base CPPP technical criterion for diligent pavement rehabilitation project selection under long-term CPPP administration. This article presents CPPP development and 2013 CPPP construction project delivery using a "smart" request for proposals process to establish a qualified products listing, by quality-based selection, on various pavement rehabilitation methods and treatment products to match project needs.
