0引言沥青路面基面层间结合状态是影响路面寿命的重要因素。良好的基面层间接触条件可以保证车轮荷载传递的连续性,使路面结构内应力分布更为均匀,有利于延长路面的使用寿命。目前,提高基面层间粘结强度的做法主要有两类:一是洒布粘结强度较好的透层材
0 Introduction Asphalt pavement base surface layer bonding status is an important factor affecting the life of the pavement. Good contact conditions between the base layer can guarantee the continuity of wheel load transmission, the stress distribution in the pavement structure more uniform, is conducive to prolong the service life of the road. At present, there are mainly two kinds of ways to improve the bond strength between base layers: one is to apply a layer of permeable material with better bonding strength
