摘要
应用胶粉对温拌改性沥青混合料进行改性,采用高温车辙试验、低温小梁弯曲试验、浸水马歇尔试验及冻融劈裂试验,系统研究胶粉掺量及细度对温拌改性沥青混合料的高温性能、低温性能和水稳定性能等路用性能的影响规律。
Asphalt was modified by using rubber powder, and high - temperature rutting test, low - temperature beam bending test, Immersion Marshall Test, and freeze -thaw split test were carried out to study the effect of mixing amount and fineness of rubber powder on the high -temperature property, low- temperature property and water stability property of warm - mixing rubber powder modified asnhalt mixture.
