基于公路沥青路面裂缝处治影响因素研究

沥青路面开裂是一种无法彻底消除的道路损坏形式,如半刚性基层的沥青路面反射裂缝、寒冷地区的沥青路面温缩裂缝等,目前均缺乏有效的措施予以彻底避免。路面出现裂缝后,雨水、雪水等沿裂缝渗入面层、基层中,使基层甚至路基软化,造成基层、路基强度降低、路面局部或成片损坏,从而导致行车速度、舒适性和安全性迅速降低,且会降低路面寿命。深入调查分析公路沥青路面裂缝处治现状及问题分析基础上,结合当前公路沥青路面裂缝处治材料的特性,开展对公路沥青路面裂缝处治影响因素进行分析研究。

Research on Influence Factors of Crack Treatment Based on Asphalt Pavement

Asphalt Pavement crack is a kind of road damage form,such as reflection crack of asphalt pavement with semi-rigid base,temperature crack of asphalt pavement in cold area,etc.At the present,there are no efficient measures to avoid it completely.After cracks appear on the pavement,the rainwater,snow water and so on seep into the surface layer and the base layer along the cracks to make the base layer or even the roadbed soften,to reduce the strength of the base layer and roadbed,and to damage the road surface locally or in pieces,thus to result in the rapid reduction of driving speed,comfort and safety,and the reduction of road life.Based on the investigation and analysis of the present situation and problems of crack treatment in highway asphalt pavement,combined with the characteristics of crack treatment materials in current highway asphalt pavement,the influence factors on crack treatment of asphalt pavement are analyzed and studied.
