大粒径沥青混合料(LSAM)强度的形成

Resistance of Large Stone Asphalt Mixes

通过三轴试验对大粒径沥青混合料 (LSAM)的强度构成参数 ,即粘聚力c和内摩阻角 φ进行了试验研究 ,并与传统沥青混合料的试验结果进行比较 ,结果表明LSAM与传统沥青混合料在强度构成上存在不同 ,从而得到了一些有价值的结论 ,为研究LSAM的力学特性和路用性能提供了理论依据。

The triaxial test was carried out to analyze the two intrinsic parameters of large stone asphalt mixes(LSAM), namely cohesion and angle of internal friction φ. The results compared with traditional asphalt mixes’show that their resistances are different, and some very important conclusions are obtained.
