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 asphalt. For example, if the specified binder grade for the mix is a PG 64-22, the required grade for the recycled mix would be a PG 58-28".
Hot mix asphalt (HMA) is extensively used worldwide for the construction of bituminous pavement. However, the need to make the pavement industry more ecological has led to the evolution of the warm mix asphalt (WMA) concept. Mixing and compaction temperatures for WMA are lower than the conventional HMA production temperatures. The reduced …
