摘　　要：根据石太高速公路河北段水泥混凝土路面破损状况,参考近年来国内相似工程的实践经验,提出路面大修方案,对加铺不同沥青结构层厚度进行了计算;大修路面设计与新建公路设计不同,要考虑主线桥涵、路面顺接等标高控制,还要考虑加铺层结构及路面整体结构的受力合理性,通过计算比较,确定了路面大修工程的技术设计方案。Based on damage condition of cement concrete pavement in Hebei Section of Shijiazhuang to Taiyuan Expressway,in combination with the experience on the same project practice at home and ahead and recent years,the heavy maintenance project was proposed,with computation of thickness of different asphalt paving structural layers.The pavement design for heavy maintenance project is different from the newly-building highway,and the elevation control and smooth connection should be considered,between the bridges and culverts in the mainline and pavement,and also the reasonableness of forcing on the paved structural layer and integrated pavement structure.By comparison,the technical design plan for heavy maintenance was determined.
