White-to-black structure for old cement concrete pavement of urban road
The white-to-black structure for the old cement concrete pavement of the urban road provided by the embodiment of the invention comprises an old cement pavement layer, an asphalt surface layer, transverse grooves, longitudinal grooves and reinforcing pieces, the top of the old cement pavement layer is provided with an asphalt surface layer composed of an asphalt mixture connecting layer laid on the top of the old cement pavement layer and an asphalt concrete layer laid on the top of the asphalt mixture connecting layer, and asphalt emulsion is further sprayed between the asphalt mixture connecting layer and the old cement pavement layer. The asphalt emulsion plays a role in improving the connection strength between the asphalt surface layer and the old cement pavement layer, which is a mode for connecting the asphalt surface layer and the old cement pavement layer in the prior art; according to the method, on the premise that the construction period is short and the work amount is small, the strength of connection between the old cement pavement layer and the asphalt surface layer can be effectively improved, the interlayer shear resistance and strength are improved, the probability of formation of interlayer gaps is reduced, and the probability of falling off of the asphalt surface layer is reduced.
本发明实施例一提供的一种城市道路旧水泥混凝土路面白改黑结构，包括旧水泥路面层、沥青面层、横槽、纵槽和加强件，旧水泥路面层的顶部设置有由铺设在旧水泥路面层顶部的沥青混合料连接层以及铺设在沥青混合料连接层顶部的沥青混凝土层组成的沥青面层，沥青混合料连接层与旧水泥路面层之间还洒布有沥青乳液，沥青乳液起着提升沥青面层与旧水泥路面层之间连接强度的作用，此为现有技术中联结沥青面层与旧水泥路面层的方式；本发明能够在保证工期短和工程量小的前提下，有效的提高旧水泥路面层与沥青面层之间联结的强度，提升层间抗剪切力的且强度，降低层间间隙形成的概率以及降低沥青面层脱落的概率。
