• Recycled Base Aggregates in Pavement Applications

    The bearing capacity decreases with increasing RAP content. The California Bearing Ratio (CBR) is reduced below that expected for conventional granular base when the amount of RAP exceeds 20 to 25 percent. Compacted Density: Due to the coating of asphalt cement on RAP aggregate, which inhibits compaction, the compacted density of blended

  • Subbase or Subgrade: Improving Soil Conditions

    A solid subbase is a key to a successful building project. A slab on ground and pavements normally are designed to be supported by a solid subbase, which needs to be uniform by nature to support the structure above it. A subbase will go on top of the subgrade, which typically is native soil or improved soil that has been compacted.

    A CLSM compressive strength of 50 to 100 psi is equivalent to the bearing capacity of a wellcompacted soil. Maintaining CLSM strengths at low levels is critical in those projects where future excavation will be required, and therefore it is often critical that mixtures be proportioned in a manner so as to minimize laterage strength increases.
