TST弹塑体材料在沥青路面裂缝修补中的应用

Application of TST elastoplastic material in asphalt pavement crack repair

交通是城市的脉搏,是经济发展的命脉。随着国内经济的蓬勃发展、我国对交通建设的大力投入,促使国内道路桥梁建设迅速发展。但公路投入使用的年限越长,出现的各类病害就越多,路面裂缝是出现最频繁的主要病害之一。路面病害处理材料及施工工艺多样,依托宜昌市三江桥中修工程施工,通过对TST弹塑体材料特性的了解,结合施工针对TST弹塑体材料修补沥青路面裂缝实用性进行分析,介绍了TST弹塑体材料性能及修补裂缝施工工艺,施工完成后效果及后期车辆通行反应良好。

Traffic is the pulse of a city and the lifeblood of economic development.With the vigorous development of domestic economy and China’s strong investment in traffic construction,domestic road and bridge construction has developed rapidly.However,the longer the highway is put into use,the more various diseases appear.Pavement cracks are one of the most frequent main diseases.There are various pavement disease treatment materials and construction processes.Based on the construction of Sanjiang Bridge medium repair project in Yichang City,through the understanding of the characteristics of TST elastic-plastic material,combined with the construction,this paper analyzes the practicability of TST elastic-plastic material in repairing asphalt pavement cracks,and introduces the performance of TST elastic-plastic material and the construction process of repairing cracks.After the construction is completed,the effect and vehicle traffic response in the later stage are good.
