摘　　要：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 。Different thickness of pavement slab,kind of concrete and spaces of joint are selected,and the first experimental stretch of Ultra-Thin Whitetopping (UTW) pavements of our country is constructed on a typical stretch of asphalt pavement of a certain national secondary road.Construction technology, service performance and applicability of UTW are discussed by constructing and observing for experimental stretch. The results indicate that bearing capability of pavement is enhanced evidently and surface roughness of pavement mended.UTW pavements have wide applied foreground in the process of rehabilization of existing asphalt pavement in our country.
