| 摘 要： | 旧沥青路面裂缝是对加铺层使用性能及寿命造成影响的最直接原因，而现有的加铺层设计方法对此考虑较为不足。针对这种情况，建立有限元模型，设定旧沥青路面开裂宽度和深度变化范围，系统研究了旧路开裂状况对沥青加铺层结构荷载内力及温度内力的影响规律，从而为旧沥青路面加铺层设计提供参考。 |

| Abstract: | The old asphalt pavement cracking is one of the reasons that directly impact on the overlay service performance and life.While the existing overlay design methods are inadequate consideration.According to this, a finite element model is built.The old asphalt pavement crack width change range and crack depth change range were set.The influence law of the old asphalt pavement cracking situation to overlay structure load inner force and temperature stress is systematically studied.The result provides reference... |
