RISEvaluating Performance of PPA-and-Elvaloy-Modified Binder Containing WMA Additives and Lime Using MSCR and LAS Tests
Publisher: American Society of Civil Engineers
Abstract: Modification of asphalt binder with Elvaloy (Elv) and polyphosphoric acid (PPA) has been reported to have better performance. However, such modification may increase mixing and compaction temperatures of asphalt binder. ...
Effect of Warm-Mix Additives and Lime on Intermediate-Temperature Fracture Property of RET- and PPA-Modified Asphalt Binder
Publisher: American Society of Civil Engineers
Abstract: Asphalt binder phase plays a significant role in cracking resistance of asphaltic mixture. Therefore, selection of appropriate asphalt binder combination becomes important, especially when asphaltic pavement is expected ...
