| 摘 要： | 采用基于弹性层状体系理论的BISAR 3.0软件,在层间接触关系为完全连续条件下,详细分析了沥青路面结构的路基回弹模量、基层回弹模量、面层回弹模量、基层厚度及面层厚度对路表弯沉值的影响规律.通过分析,发现路基回弹模量是路表弯沉值的主要影响因素,路基回弹模量与基层厚度组合变化对路表弯沉值的影响比路基回弹模量与底基层厚度、面层厚度组合变化影响大,提出了影响沥青路面结构层设计的最不利组合形式,为沥青路面结构组合设计提供参考依据.

| Abstract: | Asphalt pavement structure and changing range of structural parameters is definite. Based on the theory of multi - layer elastic system, influence law that the change of subgrade resilient modulus, semi - rigid base resili- ent modulus, surface resilient modulus, base thickness and surface thickness impact on road surface deflection is determined through software of BISAR3.0. Road surface deflection is mainly from subgrade resilient modulus. The combination of subgrade resilient modulus and semi - rigid base thickness is bigger influence than the combination of the other cases. The most unfavorable combination design of asphalt pavement structure layer is proposed. These conclusions have an important guidance significance for asphalt pavement design. |
