沥青路面的离析现象会导致沥青路面的早期损坏,大大缩短沥青路面的使用寿命,对沥青路面的性能影响较大是引起路面水损坏现象的基本原因,尤其是在北方,桥面的沥青混凝土铺装层出现离析时,在冬季就会使除雪剂透过沥青铺装层渗入到桥面水泥混凝土表面上,对水泥混凝土桥面产生腐蚀现象,影响桥面的使用寿命,给工程带来损害。现通过对沥青路面施工时出现离析现象的原因、危害的分析,从三个方面提出了减少离析现象及消除其产生后果的方法,同时提出了具体的防治措施。
Segregation of asphalt pavement will cause early damage of asphalt pavement, greatly shorten the service life of asphalt pavement and greatly affect the performance of asphalt pavement, which is the basic reason for pavement water damage. Especially in the north, the asphalt concrete pavement In the case of detachment, the deicing agent will penetrate through the asphalt pavement into the surface of the bridge deck concrete in winter to cause corrosion on the bridge deck, which will affect the service life of the deck and cause damage to the project. By analyzing the causes and the hazards of the segregation phenomenon during the construction of asphalt pavement, the methods of reducing segregation and eliminating the consequences are put forward from three aspects. At the same time, specific prevention measures are put forward.
