Crack sealing machine can be used for road maintenance and road repair, however, it is important to measure the length and width of the pavement crack.
Here are some reasons about design of pavement structure:
-
Minimize the thickness of the asphalt surface as much as possible.
Freeway pavement thickness can be reduced as appropriate, control within 9-12cm. The first is the semi-rigid asphalt pavement structure of the carrying capacity can be semi-rigid material layer (base and sub-base) to bear, without thickening the surface layer to improve the carrying capacity. The second is to improve the performance of asphalt pavement is not a thick asphalt surface layer, but with high quality asphalt. The third is the asphalt surface cracks not only reflective cracks, in normal construction, most of the asphalt surface layer itself temperature cracking. The fourth is generally thick asphalt surface layer easily lead to rut generation.
-
Strengthen the waterproof asphalt pavement design
-
Choose a reasonable grass-roots and sub-base structure
