The invention discloses a kind of bitumen concrete road surface cracks method for repairing and mending, comprising the following steps: step 1, fluting: along the trend and shape in crack slotted or expanded seam processing, obtain the line of rabbet joint；Clear slot: step 2 the concrete of the impurity for influencing bond effect on line of rabbet joint wall surface described in step 1, clast and loose crushing is removed, solid wall surface is exposed；Step 3, preparation joint filling slurry；Step 4, slip casting: the slurry of joint filling obtained by step 3 is cast in the line of rabbet joint, and is compacted to be formed the repairing block being smoothly connected with former road surface by roller；Step 5, it covers affixing kerfs belt: being completed with the junction that affixing kerfs belt is covered on the former road surface and the repairing block, the present invention overcomes the deficiencies in the prior art, the ability that asphalt concrete pavement resists vehicular load and such environmental effects can significantly be improved, extend the service life of asphalt concrete pavement, highway maintenance maintenance cost is significantly reduced, method simple practical is suitble to promote.
Description
Technical field
The present invention relates to highway maintenance fields, particularly belong to bitumen concrete road surface cracks method for repairing and mending.
Background technique
Bituminous pavement in use for some time, often will appear various different degrees of cracks, especially by crack
It can be seen that the large fracture of base, large fracture can reduce the service performance on road surface and shorten the service life on road surface.It is usually used at present
The restorative procedure of asphalt pavement crack is former pavement seam filling, and former pavement seam filling is that joint filling slurry is poured at pavement crack, through being compacted
The repairing block being smoothly connected with former road surface is formed, joint filling slurry is made of the stirring of cement, rubble, sand, water and additive.It is this
Restorative procedure has the drawback that the repairing block in pavement crack is easy to be detached from former road surface.
Summary of the invention
The object of the present invention is to provide a kind of bitumen concrete road surface cracks method for repairing and mending, overcome the prior art not
Foot using fluting, clear slot, preparation joint filling slurry, slip casting, covers five steps of affixing kerfs belt, provides bitumen concrete road surface cracks
Method for repairing and mending, this method solve the repairing blocks in pavement crack to be easy the shortcomings that being detached from former road surface.
To solve the above problems, the technical solution used in the present invention is as follows:
Bitumen concrete road surface cracks method for repairing and mending, comprising the following steps:
Step 1, fluting: along the trend and shape in crack slotted or expanded seam processing, obtain the line of rabbet joint；
Step 2, clear slot: by mixing for the impurity for influencing bond effect on line of rabbet joint wall surface described in step 1, clast and loose crushing
Solidifying soil is removed, and solid wall surface is exposed；
Preparation joint filling slurry: step 3 is weighed, 75 parts of low-heat cement, 45 parts of pitch, 90 parts of sand, mud by the raw material of following parts by weight
45 parts of soil, 12 parts of water-reducing agent, 65 parts of water, 7 parts of cold-resistant agent, 9 parts of curing agent, 28 parts of calcium carbonate, 18 parts of adhesive, reinforcing fiber 18
Part, it is spare to be mixed to get joint filling slurry；
Step 4, slip casting: the slurry of joint filling obtained by step 3 is cast in the line of rabbet joint, and is compacted to be formed by roller and be put down with former road surface
The repairing block of slip；
Step 5 covers affixing kerfs belt: being completed with the junction that affixing kerfs belt is covered on the former road surface and the repairing block.
Further, the affixing kerfs belt includes upper protecting film from top to bottom, upper coating, fibrous layer, lower coating, binder and
Lower protecting film.
Further, the affixing kerfs belt with a thickness of 2-3mm.
Compared with prior art, implementation result of the invention is as follows by the present invention:
Bitumen concrete road surface cracks method for repairing and mending of the present invention utilizes fluting, clear slot, preparation joint filling slurry, slip casting, capping
Five steps of affixing kerfs belt, provide bitumen concrete road surface cracks method for repairing and mending, this method solve the repairings in pavement crack
Block is easy the shortcomings that being detached from former road surface, can reduce the probability that the road surface after pouring generates crack, method of the invention can
Significantly improve the ability that asphalt concrete pavement resists vehicular load and such environmental effects, extends asphalt concrete pavement
Service life, significantly reduces highway maintenance maintenance cost, and method simple practical is suitble to promote.
Specific embodiment
The present invention will be further described with reference to the examples below, but the present invention is not limited to these instances, and is being de-
Under the premise of from present inventive concept, carried out by it is any improvement be within the scope of the present invention.
Bitumen concrete road surface cracks method for repairing and mending of the present invention, comprising the following steps:
Step 1, fluting: along the trend and shape in crack slotted or expanded seam processing, obtain the line of rabbet joint；
Step 2, clear slot: by mixing for the impurity for influencing bond effect on line of rabbet joint wall surface described in step 1, clast and loose crushing
Solidifying soil is removed, and solid wall surface is exposed；
Preparation joint filling slurry: step 3 is weighed, 75 parts of low-heat cement, 45 parts of pitch, 90 parts of sand, mud by the raw material of following parts by weight
45 parts of soil, 12 parts of water-reducing agent, 65 parts of water, 7 parts of cold-resistant agent, 9 parts of curing agent, 28 parts of calcium carbonate, 18 parts of adhesive, reinforcing fiber 18
Part, it is spare to be mixed to get joint filling slurry；
Step 4, slip casting: the slurry of joint filling obtained by step 3 is cast in the line of rabbet joint, and is compacted to be formed by roller and be put down with former road surface
The repairing block of slip；
Step 5 covers affixing kerfs belt: being completed with the junction that affixing kerfs belt is covered on the former road surface and the repairing block.
The affixing kerfs belt includes upper protecting film, upper coating, fibrous layer, lower coating, binder and lower protection from top to bottom
Film, the affixing kerfs belt with a thickness of 2-3mm.
