探讨公路项目沥青路面灌缝维修技术

Discussion on Asphalt Pavement Joint Filling and Maintenance Technology of Highway Project

服役年限内的公路沥青路面,已出现较多的开裂病害,因此为使沥青路面维持好的路用性能,必须加强养护工作。通过比较各种不同裂缝修复方法和灌缝材料性能,论述了沥青路面的裂缝修复技术、灌缝材料性能评估体系,并基于此开展室内试验,对四种常见灌缝胶进行材料特性及修复效果进行了评估。

Within the service life of the highway asphalt pavement,there have been many cracking diseases.Therefore,in order to maintain the good road performance of the asphalt pavement,the maintenance work must be strengthened.By comparing different crack repair methods and the performance of joint grouting materials,this paper discusses the crack repair technology of asphalt pavement and the performance evaluation system of joint grouting materials.Based on this,indoor tests are carried out to evaluate the material properties and repair effects of four common joint grouting adhesives.
