Subgrade Soil Stabilization Using Low-Quality Recycled ...

2019-3-21  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).
