ANALYSIS OF USING RECLAIMED ASPHALT

resilient modulus. Testing was also conducted on reclaimed asphalt pavement (RAP) and reclaimed concrete aggregate (RCA) to evaluate their potential use as base and subbase materials. The testing of the RAP, RCA, and their blends with the base material, showed that as the % RAP increased in the blend, both the CBR value and permeability decreased.

» Recycled Asphalt Pavement

Recycled Asphalt Pavement. The 1973 Arab Oil Embargo saw the price of crude oil rise from less than $10 a barrel to more than $35 by 1981. Suddenly binder costs, only 5% of the total mix, were now 68% of the mix materials costs. This dramatic price increase, the aging of the U.S. highway system and the realization both aggregates and binder ...
