subgrade soil stabilization using low-quality recycled

subgrade soil stabilization using low-quality recycled

Mar 21, 2019 · RCA is commonly used in the unbound base or subbase layer in pavements. Lower quality RCA (i.e., from D-cracked pavement) can be used in subgrade soil stabilization. In this study, a clay subgrade soil was stabilized using RCA and three different cementitious materials (lime, Class C fly ash, and a combination of Portland cement and fly ash). Clay soil-cement mixtures containing 0%, 50%, and 100% RCA, from two D-cracked concrete …
