公路沥青路面结构层粘接强度可靠性分析

Reliability Analysis of Adhesion Strength of Highway Asphalt Pavement Structural Layer

改革开放以来,随着中国经济的高速发展和社会建设的不断进步,交通建设也在急速向前发展,直至今日,我国公路总里程已达450万km。而沥青路面则在城市道路和公路干线的建设上得到了广泛地应用,是目前中国铺筑面积最多的一种高级路面。沥青路面的结构层都是由面层、基层、底基层、垫层组成的。各结构层层间粘接强度的可靠性,将影响到沥青路面的安全性、适用性和使用寿命。同时沥青路面暴露于大自然中,会受到气候、温度、行车等复杂的外部条件的影响。文章将通过探究沥青路面结构层的构成,不同沥青路面类型的结构层间粘接状态来分析沥青路面结构层粘接强度的可靠性。

Since the reform and opening up,with the rapid development of China’s economy and the continuous progress of social construction,traffic construction is also developing rapidly.Up to now,the total mileage of roads in China has reached 4.5 million kilometers.Asphalt pavement has been widely used in the construction of urban roads and highway trunk lines,and it is one of the most advanced pavement with the largest paving area in China at present.The structural layer of asphalt pavement is composed of surface layer,base layer,subbase layer and cushion layer.The reliability of bonding strength between layers of each structure will affect the safety,applicability and service life of asphalt pavement.At the same time,when asphalt pavement is exposed to nature and will be affected by complex external conditions such as climate,temperature and driving.In this paper,the reliability of the bonding strength of the asphalt pavement structural layer will be analyzed by exploring the composition of the asphalt pavement structural layer and the structural interlaminar bonding state of different asphalt pavement types.
