Embodiment Construction
[0036] The embodiment of the present application discloses a structure for overlapping longitudinal cold joints of asphalt concrete pavement.
[0037] Attached to the following Figure 1-3 This application will be described in further detail.
[0038] refer to figure 1 , The structure for lap jointing of longitudinal cold joints of asphalt concrete pavement includes a lap joint device 2 . In this embodiment, the asphalt concrete road that has been paved and cooled and hardened is the formed road 1, and the road that is paved in real time by the high-temperature asphalt concrete slurry is the newly constructed road. The lap joint device 2 is arranged on one side of the formed road 1, and the end of the newly built road close to the formed road 1 is poured on the lap joint device 2, so as to realize the stable connection between the formed road 1 and the newly built road, thereby reducing the cutting of the formed road 1. The step of cutting the corners improves the work effi...

The invention relates to an asphalt concrete pavement longitudinal cold joint lap joint structure and an application method thereof and relates to the technical field of asphalt pavement lap joint, the lap joint structure comprises a lap joint device used for connecting a formed road and a newly-built road, and the lap joint device comprises a connecting part and a positioning part; the connecting part and the positioning part are each provided with a slurry seepage channel in a penetrating mode, and asphalt concrete slurry can penetrate through the slurry seepage channels. The connecting part comprises a pulp collecting box, and a preset part used for being connected with the pulp collecting box is arranged on the forming road; the connecting part is arranged on the side, away from the forming road, of the pulp collecting box and used for limiting the position of the pulp collecting box. The lap joint method comprises the steps of positioning, connecting and paving. The construction method has the effects that the working efficiency of lapping and paving the asphalt concrete road by constructors is improved, and the connection stability of a newly-built road and a formed road is effectively guaranteed.
Description
technical field [0001] The present application relates to the technical field of lap jointing of asphalt pavement, and in particular, to a structure for lap jointing of longitudinal cold joints of asphalt concrete pavement and an application method thereof. Background technique [0002] Asphalt concrete road is a road with excellent mechanical properties, strong shock absorption and noise reduction, and high driving comfort. In the construction of asphalt concrete roads, the asphalt concrete roads that have been constructed will cool and harden after a period of time, while the asphalt concrete roads that are poured subsequently are in a high-temperature molten state, and the two are lapped by cold joints, which often need to be lapped. Equipment treatment to ensure the forming quality of two asphalt concrete roads after overlapping. [0003] In the actual processing of asphalt concrete roads, most of the construction workers first cut off the edges and corners of the forme...
