The Most Effort-save,Economical, and Effective Way to Repair the Crack of Asphalt Pavement
The most effort-save,economical, and effective way to repair the crack of asphalt pavement
Cracks are one of the most common, most susceptible, and earliest diseases in various types of damage to the pavement. It is almost accompanied by the entire use period of the pavement and worsen with the growth of road age.
Cracks on the road not only affect the beauty of road capacity and the comfort of driving, but also easily expand, causing the structure of the road surface to destruction, and shortening the service life of the road.
Cracks appear on the pavement, which should be repaired in time to prevent rainwater and other debris from entering the lower layer and roadbed along the cracks, otherwise it will cause the road carrying capacity to decrease and the road damage will accelerate.
The asphalt pavement stitching is a new type of highway maintenance material specializing in asphalt and cement concrete road cracks. It mainly treats contraction cracks and some structural cracks.
Five advantages of asphalt pavement pressing sewing
1. No need to process or reinforce connection
The asphalt pavement pressing construction does not require slotting or heating, and will not cause damage to the fragile crack areas. The pressing of the sewing and the crack area will form a dense connection body, strengthen the strength of the crack area, and effectively prevent loosening in the crack area. , Crash, crash, pits, etc.
2, anytime, anywhere, simple and fast
The operation is simple, no equipment is required, and the cracks can be opened to traffic.
If you have sewing anytime, anywhere, you do n’t need to wait until there are a large number of cracks on the road to deal with it to prevent the cracks from further damage to the road.
3, reduce costs, economical and practical
The low prices of asphalt pavement stitching and the investment without too much equipment and labor costs fully reflect its economy.
4, multi -party application and excellent performance
The asphalt pavement pressing can be used at the same time for the treatment of the construction seams, shrinking joints and some structural cracks of asphalt and cement pavement. It can also be used for crack treatment before the construction of road drainage and sealing.
5, energy conservation and emission reduction, environmental protection and beauty
The asphalt pavement presses the construction process without noise and flying dust, which has a minimum impact on the construction staff and construction areas.
The design width of the 3cm of the seam can not only effectively achieve the effect of water sealing, but also avoid the pollution of the road surface caused by the crafts and other processes.
The construction requirements of asphalt pavement stitching
Clean the surface of the surface before construction and the mixed objects in the sewing. When the cracks are clean and dry, the asphalt pavement presses seams. When paste it, one hand is used to hold the material, and the other thumb and index finger should be pinched. Paste.
At the same time, it is guaranteed that there is at least 1cm overlap width at the ends of the crack. After artificial compacking, it can open the transportation paper to open the traffic.
Construction temperature requirements
The temperature of the road table should be above 15 ° C during the construction of asphalt pavement stitching; the temperature of the road table at the construction of the cement concrete pavement should be above 20 ° C.
Crack width requirements
The asphalt pavement presses can handle the contraction cracks below 1cm and some structural cracks. During the construction process, it is necessary to ensure that at least 0.5cm overlap width at both ends of the crack must be ensured.
Crack cleaning requirements
Just use a brush to brush to the surface of the cracks and the sundries inside the seams.
other requirements:
When using asphalt pavement, it must be compacted in time after bonding; the cracks must be clean during construction.
