摘要
根据高寒地区典型的气候条件,采用有限元方法分析了瞬态温度场,并在此基础上对路面结构进行了温度应力模拟,通过分析得出:设置沥青稳定碎石基层使半刚性材料层下移,有利于改善其温度状况,减少半刚性材料层的温度裂缝,从而降低沥青路面反射裂产生的可能性。
According to the alpine region the typical climatic conditions,using finite element analysis of transient temperature field,and on this basis,carried out on the pavement thermal stress simulation,analysis and insight: Set asphalt treated base course to make semi-rigid material layer down,it will help to improve the temperature conditions,reducing the temperature of semi-rigid material layer cracks,thus reducing reflection cracking of asphalt pavement resulting possibilities.
