摘　　要：从半刚性基层材料———水泥稳定土、石灰稳定土、石灰工业废渣稳定土入手,对半刚性基层材料的湿胀干缩性和热胀冷缩性进行了分析,对施工期沥青面层的温缩裂缝、反射裂缝和对应裂缝进行分析,得出沥青路面施工期出现开裂的主要原因.Beginning with the semi-rigid base course, the steady-soil of cement, the steady-soil of lime and the steady-soil of waste residue, the paper analyzes the cracks of semi rigid bituminous pavement caused by the wet-swell and dry-draw, the hot-swell and cold shrinkage. Cracks caused by the temperature drop, reflex-crack and correspondence-crack in construction are also analyzed. The asphalt pavement cracks in construction period are found out. It has certain practical application reference value for the construction of bituminous pavement.

关 键 词：半刚性基层 沥青路面 开裂
