我们知道,路面面层主要是承受行车的磨耗及水平力的剪切作用,而柔性面层如沥青混凝土已不能沿用过去的强度指标来衡量其好坏,应以多轴向负载的三轴剪切强度来衡量才是确切的。本文主要研究了利用国产沥青作为结合料的碎、砾石沥青混凝土在常温和高温时的抗剪强度,以及在高温时不同施荷速度时对它的影响。我们利用了这些强度指标修建了一些试验路,获得了初步的预期效果。 We know that the road surface is mainly to bear the wear and horizontal force of the shear effect, and the flexible surface layer such as asphalt concrete can no longer use the past strength indicators to measure its good or bad should be multi-axial load triaxial shear Cutting strength to measure is accurate. In this paper, the shear strength of crushed, gravel asphalt concrete at home temperature and high temperature, as well as the influence of different applied load speed at high temperature, on domestic asphalt are studied. We used these intensity indicators to construct some experimental roads and obtained the preliminary expected results.
