Using Recycled Concrete Aggregate in Pavement Base

base applications are the most common uses for recycled concrete aggregate (RCA) produced from concrete pavement slabs (Snyder 2020). The widespread ac-ceptance of RCA in pavement base layer ap-plications is probably because these uses offer some of the greatest environmental benefits at a low cost, while providing the
