Waterproof edge sealing construction method for asphalt pavement pit slot joint
The invention provides a waterproof edge sealing construction method for an asphalt pavement pit slot joint. The waterproof edge sealing construction method comprises the steps: excavating a square foundation trench, aligning a pit slot by using a theodolite, and measuring the lengths of the pit slot of a straight line section along the longitudinal and transverse directions of an original pavement respectively; or measuring the length of the transverse side of the pit slot of an arc road section along the diameter direction of the arc and the length of the longitudinal side tangent to the edge of the arc, and thus obtaining the slotting size. A slot needs to be square or rectangular, a wire frame needs be parallel or vertical to the road center line, and the slot is cut along the line drawing position by a cutting machine according to the principle of 'round hole and square opening'. An iron pickaxe is forbidden, an asphalt pavement pit slot is directly repaired and ground by adoptinga hot-mixed asphalt mixture, and then the surface of a joint is reinforced by adopting epoxy asphalt binder coating, non-woven fabric laying, SBS modified asphalt coating, gravel spraying and the like, so that the connection strength of the joint is effectively ensured, the joint stress is greatly reduced, and the service life of pit slot repairing is prolonged.
本发明公开了一种沥青路面坑槽接缝处防水封边施工方法，开挖方形基槽，使用经纬仪对坑槽进行定线，测量直线路段的坑槽分别沿原路面纵横向的长度，或测量圆弧路段的坑槽沿圆弧的直径方向的横边长度以及相切于圆弧边缘的纵边长度，从而得出需要开槽的尺寸，开槽必须成方形或矩形，同时线框必须保持与路中线平行或垂直，开槽遵守“圆洞方开”的原则，用切割机沿画线位置进行切割，禁止用铁镐直接进行，通过对沥青路面坑槽采用热拌沥青混合料进行修补、碾压之后，对接缝处表面采用涂刷环氧沥青粘结剂、铺设无纺布及涂刷SBS改性沥青并洒布碎石等进行加强处理，有效保证了接缝处的连接强度，大幅降低了接缝受力，延长坑槽修补的使用年限。
