この発明はアスファルト舗装路のひび割れ補修法に関す

を提案するにある。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for repairing cracks in asphalt pavement. That i! The aim is to propose a repair method that has excellent moisture retention in the repaired area and load transmission to the road surface, and can prevent cracks from expanding over a long period of time.

填し水の没入を防止し、ひび割れの拡大中地盤の軟弱化
を防止していた。Conventionally, concrete crossroads have been designed to have joints at predetermined intervals so that crack stress is concentrated at the joints, and damage such as cracks is difficult to occur, and damage such as cracks is difficult to occur. When cracks occur, most of the time the repair method using overlay is selected as described in Road Maintenance and Repair Guidelines 1-'A-4 (page 94). On the other hand, asphalt pavement has the disadvantage that cracks are more likely to occur than #1IFIL. After a crack occurs, water infiltrates from the 0 part and expands the crack, and further water infiltrates into the ground below, weakening the ground.In both cases, poor load transmission on one wheel further promotes the expansion of the crack. . Therefore, conventionally, if a crack occurs, filler is filled into the cracked area as soon as possible to prevent water from entering and to prevent the ground from weakening while the crack is expanding.

物を充填していた。Conventionally, a filler such as cement paste, mortar, asphalt/rubber, asphalt/crete, or epoxy resin has been directly filled into the cracked area.

どの欠点が起り易かった。However, when the filling is directly filled into the cracked part, the inner surface of the crack becomes uneven, and the filling cannot be filled with writing on the cracked surface, making it impossible to impart sufficient watery properties, and the filling may be incompletely filled. As a result, when the asphalt pavement becomes soft during high temperatures such as in the summer, the filler tends to fall into the cracks, creating recesses above the filler and facilitating water infiltration.

である。This invention is an improvement on the above-mentioned conventional repair method, and its gist is that #1
One step to filling and repairing, cracked part 111 in advance
This is a crack repair method in which the 1R surface is enlarged into a roughly U-shaped groove to make it easier to fill with filler, and a continuous curved surface is provided from the lower end of the side wall of the groove to f5@.

て水蜜性が向上し、ひび割れの拡大や下地地盤の軟弱化
をもたらさない。According to this repair method, the opening is enlarged and the filler is filled into the groove, which has a U-shaped bottom and a continuous curved surface from the lower end of the side wall to the bottom, so that the filler adheres closely to the groove surface and interfaces with the groove. No voids are left in the cracks or corners, and the filler does not fall into the cracks and create recesses on the top surface. Therefore, water resistance is improved, and cracks do not expand or the underlying ground becomes soft.

に拡大開口する。Examples will be described below with reference to the drawings. Figure 1 shows two parts of cracks that have occurred in asphalt pavement 1, and this part has a U-shaped cross section along the length direction with the crack as the center.
Expand the aperture to .

る。This groove 5 has a continuous curved surface 6 extending from the lower end of the wall 4 to the bottom surface 5 as shown in FIG. The repair is completed by filling the asphalt rubber concretion 7 into the #l13.

きた。Filling 7 was tightly packed on the inner surface of @S, leaving no voids, and was highly watertight, preventing water from penetrating, and preventing the expansion of cracks and weakening of the underlying ground. .

。Note that the shape line width of the groove 5 and #l! If the width or depth is approximately the same, it is easy to fill the filling densely, and the stability after filling is excellent.The width or depth is usually 1O-i50.
■It's about. Watertightness can be further improved by applying an anchor coat to the inner surface of the groove to improve adhesion to the inner surface of the groove prior to filling. As the anchor coating agent, asphalt emulsion, cutback asphalt, etc. are suitable.
