剖析沥青路面早期破损成因及提出预防措施

沥青路面具有表面平整、坚实、无接缝、行车舒适、耐磨、噪声低、施工期短、养护维修简便且适宜于分期修建等优点。在公路与城市道路修建中已广泛应用。虽然沥青路面设计是建立在层状弹性理论基础上的耐久性设计,但沥青路面仍然存在设计年限内发生的早期破损现象。该文从工程施工角度,分析了造成早期破损现象的施工与原材料方面的原因,并提出相应的预防及改善措施。

Analysis of Early Disrepair Cause of Asphalt Pavement and Its Prevention Measure

The asphalt pavement has the characteristics of the flat surface,stability,no joint,comfortable driving,wearing resistance,low noise,short construction period,simple maintenance and being suitable for construction by stages.It has been widely applied in the repairing and construction of the highways and urban roads.The design of asphalt pavement is the durable design set up on the basis of layered elastic theory,but the early disrepair appearance still exists on the asphalt pavement within the designed year...
