Evotherm温拌沥青混合料性能研究

Research on Performance of Evotherm Warm-Mix Asphalt

采用AC-13和AC-25两种级配,对Evotherm温拌沥青混合料(E-WMA)的各项性能指标进行了研究,并与相同级配的热拌沥青混合料(HMA)进行对比分析.结果表明,Evotherm温拌沥青混合料在高温稳定性、低温抗裂性能等方面与相同级配的热拌沥青混合料相当,水稳定性稍逊,而疲劳性能则明显占优.

The Evotherm warm-mix technology is a new kind of warm-mix technology. Two gradings（AC-13,AC-25） of Evotherm warm-mix asphalt（E-WMA） were chosen to study the performance indicators of E-WMA, and comparison with HMA which had the same grading as that of E-WMA was made. The re- suits show that high temperature stability, low temperature cracking etc. of E-WMA is on the same level with HMA; and the fatigue performance is much better than that of HMA. But the water stability is not as good as that of HMA.
