三种岩沥青室内试验性能对比

该文阐述了三种岩沥青室内性能试验的情况。通过对三种岩沥青进行沥青含量的测定,测得A、B、C岩沥青样品的沥青含量分别为34.3%、28.6%和33.7%。根据送样要求进行室内配合比设计,结果表明:A、B、C三种岩沥青对沥青混合料的高温性能和水稳定性都有不同程度的提升,对低温弯曲性能有所衰减。综合三种岩沥青对混合料性能的影响程度,B型岩沥青性能最优。

Comparison of Laboratory Experimental Performances of Three Rock Asphalts

The article sets forth the laboratory experimental performances of three rock asphalts. The asphalt contents of three rock asphalt samples A, B and C are mensurated separately by 34.3%, 28.6% and 33.7%. The laboratory mixing ratios are designed according to the sample requirements. The results show that three rock asphalts A, B and C will improve the high-temperature performance and water stability of asphalt mixture to the different extents and attenuate the low-temperature bending performance a little. The performance of rock asphalt B is the most excellent by summing up the influence extents of three rock asphalts on the mixture performance.
