半柔性材料作为长寿命沥青路面基层的适用性研究
Research on Adaptability of Semi-flexible Material as Long Life Asphalt Pavement
半柔性材料作为一种新型的路面材料，既具有半刚性材料的刚度特性，又具有一定的柔性材料的耐疲劳和抗温缩特性。本文通过拟定典型结构，并假设层间连续，采用BISAR3.0计算了不同基层厚度下半刚性基层长寿命沥青路面和半柔性基层长寿命沥青路面的受力状态，分析了半柔性和半刚性材料的温缩性能，研究了半柔性材料作为长寿命沥青路面基层的适用性，结果表明半柔性基层长寿命沥青路面对重载有良好的适应性。
Semi-flexible material as a new type of road surface materials,both has the stiffness properties as semi-rigid material,but also has a certain degree of fatigue tolerance properties and anti-temperature shrinkage as flexible material.In this paper,through the development of a typical structure,and assuming continuous layer,using BISAR3.0 calculated the force state of long-lived semi-rigid asphalt pavement and long-lived semi-flexible asphalt pavement under different thickness of base.Proposed that the semi-flexible material is more adapted to overloading road as a long –life asphalt pavement’s base than semi-rigid material.
