New and old roadbed base layer splicing seam construction method
The invention relates to a new and old roadbed base layer splicing seam construction method, and relates to the technical field of new and old roadbed splicing construction. The method comprises the following steps: S1, lofting a pavement splicing seam position; s2, a cement board within the range of a road shoulder of the old pavement is excavated, and an asphalt layer is additionally laid on the top; s3, steps are excavated at the joints of the old pavement, so that the old pavement can be conveniently spliced with the new pavement in the transverse direction; s4, laying a cushion layer and a subbase layer; s5, a concrete layer is poured at the joint between the new pavement and the old pavement, and reinforcing is conducted through a reinforcing mechanism so that the connecting strength of the new pavement and the old pavement can be improved; paving a base layer; and S6, an asphalt surface layer is laid. The method has the effect of prolonging the service life of the old pavement.
本申请涉及一种新老路基基层拼接缝施工方法，涉及新老路基拼接施工技术领域。其包括以下步骤：S1：放样出路面拼接缝位置；S2：挖除旧路面路肩范围内水泥板，以及顶部加铺沥青层；S3：在旧路面的接缝处进行台阶挖设，便于横向与新路面拼接；S4：铺设垫层和底基层；S5：在新路面与旧路面之间的接缝处浇筑有混凝土层，并利用加固机构的加固，以提高新路面与旧路面的连接强度；然后铺设基层；S6：铺设沥青面层。本申请具有延长旧路面的使用寿命的效果。
