| 摘 要： | 针对目前旧水泥混凝土路面加铺沥青层存在的普遍现象,在分析沥青加铺层温度场及温度应力的基础上,对某公路不同沥青加铺层的温度荷载应力进行分析。结果表明:对旧水泥混凝土路面进行处治、修复和采取防范措施后加铺沥青层,效果较直接加铺沥青层应力状况有了明显改善,建议在实际工程中先改善传荷能力,再铺设STRATA应力吸收层。

| Abstract: | Aimed at the general phenomenon in paving asphalt layer on old cement pavement, the temperature load stresse of different asphalt overlays were analysed based on the analysis of asphalt overlay on temperature field and temperature stress. The result shows that after repairing the old cement concrete pavement and taking some measures, the stress condition of asphalt overlay is developed obviously. It is suggested that the STRATA stress absorbing layer should be paved after improving the load transfer capacity in actual projects |
