摘要
通过对高速公路沥青路面产生开裂的原因分析,研究了一种对沥青和水泥混凝土都具有粘结强度,并且具有高延展、防水性能的改性聚氨酯材料。介绍了一种操作方便、工期短、对交通影响小的施工方法,达到了有效、方便、快速修复高速公路沥青路面裂缝的目的。
With the analysis on the crack reason of expressway asphalt pavement,a kind of modified polyurethane material is studied,which has not only bond strength to asphalt and cement concrete,but also high prolonged and waterproof performance.The construction method,which is easy operating,short construction period and less effective to transportation,is introduced.And the purpose of effectively rapid repairing the crack of expressway asphalt pavement is reached.
