高速公路沥青路面结构层层间粘接稳定性状态研究

Study on Stability of Interlayer Bonding of Expressway Asphalt Pavement Structure

近年来,我们社会经济处于高速发展状态,各行业在这一发展浪潮中也取得了长足的进步。高速公路作为道路运输的重要组成部分,在交通建设方面占据着重要地位。目前我国高速公路均采用沥青路面,沥青路面也是当前应用最为广泛的高级路面。沥青路面结构层丰富,分别包含面层、基层、垫层等部分。各结构层层间粘接的稳定性直接影响着高速公路沥青路面的使用年限及安全性。该文深入探究了不同沥青路面结构层的层间粘接情况,并创建出了相应的滑动系数取值表,进一步掌握结构层层间粘接状态和各类型沥青路面之间的关系。

In recent years,our social economy is in a state of rapid development,various industries in this wave of development has also made considerable progress.As an important part of road transportation,expressway occupies an important position in traffic construction.At present,the expressway in our country adopts asphalt pavement,which is also the most widely used high grade pavement.The asphalt pavement structure layer is rich,including surface layer,base layer,cushion layer and so on.The stability of adhesion between layers of structures directly affects the service life and safety of expressway asphalt pavement.In this paper,the interlayer bonding situation of different asphalt pavement structural layers is deeply explored,and the corresponding sliding coefficient value table is created,so as to further master the relationship between the interlayer bonding state of the structure and various types of asphalt pavement.
