本课题选择不同路面板厚度、混凝土种类和板接缝间距 ,在 2 10国道铜黄段二级公路沥青路面上修筑了我国第一条超薄水泥混凝土 (UTW)路面试验路。通过试验路修筑和观测与分析 ,对 U TW路面的施工技术、使用性能和在我国的适用性进行了研究。结果表明 ,U TW路面明显提高了路面承载能力 ,改善了路面表面平整度 ,在旧沥青路面维修中有广阔的应用前景 This topic chooses different road slab thickness, concrete types and board joint spacing, and builds the first test road of ultra-thin concrete road (UTW) in China on the asphalt pavement of Grade 2 highway of Tong-Huang Section of State Road 2 10. Through the test road construction and observation and analysis of the U TW pavement construction technology, performance and applicability in China were studied. The results show that U TW pavement significantly improves the bearing capacity of the pavement and improves the surface flatness of pavement, which has a broad application prospect in the maintenance of old asphalt pavement
