摘　　要：半刚性路面开裂一直是业内人士研究的课题。通过开裂原因的分析,确定了在济徐高速公路中,采用较低设计强度,基层混合料采用嵌挤式结构,并在施工中对上下基层连续铺筑等一系列防止半刚性路面开裂的技术措施,基层均未收缩开裂,铺筑沥青后,路面完好。Semi-rigid pavement cracking is always the subject to be studied by insiders. Through cause analysis, a series of technical measures preventing the crack, including low design strength, multilevel dense built-in gradation for base mixture, upper and lower base continuous paving during construction, is used for Jining-Xuzhou Highway. As a result, the base is not shrinked and cracked and after asphalt paving, the pavement is sound.
