摘　　要：机场旧水泥混凝土道面采用改性沥青进行盖被,是解决跑道损坏问题的有效方法。针对盖被层厚度问题,首先分析了国内外厚度计算公式的特点,通过大型的室内足尺板试验对反射裂缝与沥青盖被层厚度的问题进行试验研究,又对沥青混合料的类型与盖被层厚度的关系进行了分析,结合我国的实际情况,提出了确定机场道面沥青盖被厚度的既经济又可行的方法。To adopt modified asphalt thickening on airport old cement concrete pavement, it is one of effective methods to solve runway-mangling problem. Aiming at the asphalt covering layer thickness problem, the characteristic of the thickness calculation formula domestic and overseas firstly were analyzed, trough lull scale test to test and research reflection crack and asphalt covering layer thickness in large room, and relation between asphalt concrete＇s type and covering layer＇s thickness were analyzed. An economic and feasible method to certain airport pavement asphalt covering layer thickness was put forward.
