When a pothole appears on the road surface, the traditional construction process is to adopt a seam pressing belt or an anti-cracking paste. The joint strip is illustrated by an example, one surface of the joint strip is made of an anti-wrinkle heavy-load-resistant polypropylene material (without adhesiveness) with the thickness of 0.3mm, the other surface of the joint strip is made of a polymer waterproof film (with adhesiveness) with the thickness of 2mm, the joint strip is subjected to a new road surface and an old road surface edge sealing process, as shown in fig. 2, after disease paving and rolling are finished, a disease edge line is firstly poured into the edges of the disease and the original asphalt road surface by hot asphalt (hot pouring) 6 or finished pouring glue (cold pouring), and then the joint strip is attached to the edge of the new road surface and the old road surface, so that due to the material characteristics, the water seepage index and the adhesiveness at the joint of the new road surface and the old road surface are poor.
Based on this, as shown in fig. 3, the utility model discloses new and old road surface banding side face subsides of pothole, including the welt 10, both surfaces of welt all have the cohesiveness, and one surface is used for pasting the vertical upright wall in the old road surface after the pothole mills, and another surface is used for gluing with the mixture that waits to pave. The strip 10 is a composite waterproof adhesive (such as an asphalt cementing material), is solid at normal temperature and is colloidal when meeting high temperature; when the temperature rises to the preset temperature, the welt is changed from solid to colloid, namely, the welt can be directly changed from solid to colloid in the process of paving the mixture, so that the joints between the new and old pavements are fully filled with the compound waterproof glue during rolling, and the new and old pavement slabs can be well connected. In addition, protective films 11 are attached to both surfaces of the seal tape 10, respectively, to protect the seal tape. The mixture is preferably a common asphalt material, the softening point of the welt is 75-110 ℃, and the welt is matched with the paving temperature of the mixture of 130-160 ℃, so that the welt is converted into a colloid state from a solid state in the paving process of the mixture.

The edge sealing side of the new and old pavement of the pit hole of the embodiment of the utility model is pasted with a roll of adhesive tape, which is very convenient for carrying; the cutting can be carried out according to the sizes of different pits; finally, the problem of bonding of the old asphalt pavement and the new asphalt pavement can be effectively solved, so that the asphalt pavement and the old asphalt pavement form regional integrity, and the waterproof effect is effectively achieved.
Based on the utility model discloses new and old road surface banding side subsides of pot hole, the embodiment of the utility model provides a still provide new and old road surface banding structure of pot hole, its concrete construction method, including following step:
firstly, milling a pothole, and selecting a side surface patch matched with the pothole according to the depth of the pothole; specifically, the damaged layer corresponding to the pit hole is milled, and air blowing and cleaning can be performed after milling is completed, so that the connection performance of new and old pavement plates can be improved; as shown in fig. 4, the middle layer and the upper layer corresponding to the pothole may be milled and then spread, and only the side surface sticker needs to be arranged on the upper layer, or of course, the side surface sticker may also be arranged on the middle layer, and the description will be given by way of example by arranging the side surface sticker on the upper layer.
And step two, after the milling of the damaged layer is finished, fixing the adhesive tape of the asphalt cementing material at the joint of the new road surface and the old road surface in a solid state, specifically, tearing off the protective films on the two surfaces of the adhesive tape, and adhering the right surface of the adhesive tape to the vertical wall of the old road surface milled by the pot hole and leveling the right surface of the adhesive tape with the vertical wall. In addition, in order to prevent the side surface strips from falling off, the attachment strips can be fixed on the vertical wall of the old pavement milled by the pits through fixing pieces (such as iron nails, steel nails and the like), and the condition that the side surface strips are easy to be pushed by asphalt mixture in the subsequent paving process and cannot generate the corresponding effect, so that early diseases at the seams of the old pavement and the new pavement are generated can be prevented.
Paving the mixture, wherein the mixture covers the other surface of the adhesive strip to obtain the edge sealing structure of the new and old pavement of the pit hole; and rolling after paving. Specifically, the mixture is preferably asphalt, the asphalt is paved through a paver, the paving temperature of the mixture is 130-160 ℃, and after paving is completed, the asphalt mixture covers the left surface of the sticking strip; after the preparation of each procedure is finished, normally spreading and rolling, and changing the cementing material into colloid by using the characteristic that the asphalt cementing material is solid at normal temperature and is colloid at high temperature so as to replace the traditional crack pouring adhesive.
As shown in fig. 5, the water seepage test is performed on the edge sealing construction method for the new and old road surfaces of the pot hole and the traditional construction process, so that the traditional edge sealing process cannot meet the standard requirement at the side line during the water seepage test, and the numerical value difference is large (such as the upper curve in fig. 5); and adopt the utility model discloses the banding technology of embodiment can satisfy standard requirement basically in sideline department during the infiltration test, and the infiltration has great promotion (like the lower curve in fig. 5) than traditional technology. Therefore, the utility model discloses old and new road surface sealing side face subsides of pot hole are applied to the seam crossing on old and new road surface of pot hole, can effectively solve old and new bituminous paving's bonding, make its formation regional wholeness, effectively play water-proof effects.
The foregoing has been a detailed description of the preferred embodiments and principles of the present invention, and it will be apparent to those skilled in the art that variations may be made in the specific embodiments based on the concepts of the present invention, and such variations are considered as within the scope of the present invention.
