添加抗车辙剂的沥青混合料性能试验研究

Test Research on Asphalt Mixture Modified by Rutting Resistance Additive

研究添加了抗车辙剂路孚8000誖的沥青混合料的各项性能,对抗车辙剂不同掺量下的沥青胶结料进行基本性能试验,包括高温车辙、低温弯曲和冻融劈裂试验,结果表明:改性沥青混合料掺入抗车辙剂后,动稳定度提高显著;改性沥青混合料的抗水损害性能变化不大;混合料的低温抗裂性能略有提高。

Performances of asphalt mixture modified by rutting resistance additive LF8000 are tested. The basic tests such as the rutting tests, low temperature bend tests and frost thawing split tests are done. The results show that the rutting resistance additive can advance the dynamic stability of asphalt mixture greatly, the water resistance performance of modified asphalt mixture changes very little, and the crack resistance performance at low temperature is enhanced slightly.
