| 摘 要： | 以多层弹性层状体系理论双圆均布荷载为基础,结合国外长寿命路面设计方法及要求,对重载情况下半刚性基层沥青混凝士路面的沥青混凝土层拉应变分布规律进行研究.结果表明.对于半刚性基层的长寿命路面而言,有必要将中面层底部的拉应变作为控制指标之一.在半刚性基层的长寿命路面设计中.控制指标不仅要考虑沥青混凝土层层底拉应变.也要考虑沥青混凝土表面层的托应变.

| Abstract: | In order to find out the regularity of tensile strains in semi-rigid base asphalt concrete pavement under heavy load traffic based on the linear elastic multi-layer theory of dual-circle uniform distribution load,and according with the long-life pavement deign methods abroad.The results indicate that,considering the semi-rigid base long-life asphalt concrete pavement,it is necessary to take the tensile strains at the bottom of middle-layer as control index.In the design of the semi-rigid base long-life asph... |
