• Subgrades and Subbases for Ss| Concrete Construction

    Nov 22, 2017· Place a concrete floor on an unstable subgrade or subbase and you’ll probably pay for it two ways. During construction you’ll either waste concrete or end up with a floor that’s too thin in spots because the subgrade/subbase is uneven. After construction, the floor is likely to settle and crack because of poor subgrade/subbase support.

  • Subgrade Soil Stabilization Using Low-Quality Recycled

    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).
