摘要
文章结合半刚性基层路面建设的实际情况,采用以弹性层状体系理论为基础的bisar计算程序,分析了半刚性基层在荷载和温度共同作用下的影响因素,探讨了基层开裂与面层厚度的关系,提出了适合亚热带地区气候特征的半刚性基层上沥青面层的厚度,对公路建设有参考作用。
Considering the actual condition of semi-rigid base course,the Paper,using the bisar calculation procedure on basis of multi-layer elastic system theory,analyzed the influencing factors for semi-rigid base course under the combined effect of load and temperature.It discussed the relation between the base crack and base thickness,and proposed proper thickness for asphalt coat layer of semi-rigid base course,which is suitable for subtropical area.It provides reference for highway construction.
