摘　　要：随着沥青混凝土路面得到广泛应用,沥青路面水稳基层结构也得到广泛的应用。沥青混凝土路面水稳基层因没有合理设置胀缝,易引起水稳基层膨胀起拱和收缩开裂现象,综合分析后,明确了水稳基层胀缝设置的必要性及预防措施。Highway asphalt concrete pavement has been widely used,and the water-stabilized base structure of asphalt pavement has also been widely used.The expansion joint of water stabilized base course of asphalt concrete pavement is not reasonably set,which is easy to cause expansion arch and shrinkage cracking of water stabilized base course.After comprehensive analysis,the necessity and preventive measures of expansion joint setting of water stabilized base are clarified.
