Component Analysis - Asphalt Institute - Pavement Interactive

Subgrade material testing is encouraged even if original design records are available. The resilient modulus (MR), CBR or R-value tests appear to be the easiest to use with this procedure. For actual design, the design strength of the subgrade must be characterized in terms of resilient modulus. Therefore CBR and R-values must be correlated to resilient modulus values. If test data in terms of MR, CBR, or R-value are not available, subgrades can be placed into one of three classes for design pur

When 16 to 25% RAP is used: “The selected binder grade for the new asphalt is one grade lower for both the high and low temperature stiffness than the binder grade required for a virgin asphalt. For example, if the specified binder grade for the virgin mix is a PG 64-22, the required grade for the recycled mix would be a PG 58-28”.
