| 摘 要： | 大粒径沥青碎石具有抗车辙能力及抵抗反射裂缝的能力,能解决现在路面使用中出现的高温稳定性差和耐久性差的问题。目前大粒径沥青混合料大多用作沥青路面基层,但对其作为下面层的研究和使用相对较少,通过对不同厚度的大粒径沥青碎石下面层进行力学计算,得出大粒径沥青混合料作为下面层合理厚度取10～11cm较合适。

| Abstract: | Large-particle asphalt and crushed stone is resistant against wheel track and reflection, and it could better solve poor stability and durability of pavement at high temperature. At present, large-particle asphalt mixture is mainly used as substratum of asphalt pavement, but research and use of lower course are relatively less. After mechanical calculation of lower course made of large-particle asphalt and crushed stone, it is obtained that the reasonable thickness of lower course made of large-particle asphalt mixture should be 10 to llcm. |
