采用AC-20C型混合料,在试验室内进行抗车辙温拌沥青混合料集料及沥青温度的试验,研究表明,该混合料集料温度在160～170℃,沥青温度在145～160℃时,既可以使抗车辙剂PR PLAST.S软化,又可以达到温拌节能低温施工的效果。进一步通过温拌及热拌混合料性能对比发现,抗车辙温拌沥青混合料的性能与热拌基本相当,而温拌冻融劈裂试验作为抗车辙温拌沥青混合料水稳定性的主控指标,相对浸水马歇尔试验较为合理。
The AC-20C mixture was used to test the anti-rut temperature mixed asphalt aggregate and asphalt temperature in the laboratory. The results show that when the aggregate temperature is 160 ~ 170 ℃ and the asphalt temperature is 145 ~ 160 ℃, It not only softens the anti-rutting agent PR PLAST.S, but also achieves the effect of warm mix and energy saving low temperature construction. Through the comparison of the properties of warm mix and hot mix, we found that the performance of anti-track warm mix asphalt is basically the same as hot mix, while the warm mix freeze-thaw splitting test is the main control of water stability of anti-rut warm mix asphalt mixture Indicators, the relative water Marshall test is more reasonable.
