1. According to the width of pavement crack (crack) joint, the crack (crack) joint below 1 mm -3 mm is at least 25cm anti-crack paste; 2, crack (crack) joints with mm width below 3mm-5, and at least 33cm.
3. The crack (joint) seam with a width between 5 mm and 19 mm must be cleaned and filled with sealant, and then affixed with 50cm anti-crack paste.
4. The crack (joint) joint and subsidence area with a width above 19mm must be cleaned, filled with rubber sand, sealant or asphalt mixture and compacted to the existing height, and then affixed with 100cm anti-crack paste.![factory price earthwork products Anti-Crack Patch_8]()
5. For cracks or pits of more than 50mm wide, they must be cleaned up first, and then filled with rubber sand or hot asphalt mixture and compacted to the existing height, and then use 100cm anti-crack paste seam.
6, for different height of crack (joint) and subsidence area, must be leveled.
Note:
(1), the cement concrete pavement must be dry before construction. The base surface shall not be constructed in wet and rainy and snowy days.
(2), After construction, must use sand bag or rubber tire roller will be "anti-crack" compaction, in order to prevent the rain before paving asphalt concrete into the "anti-crack" adhesive surface. If it is expected to rain heavily before spreading asphalt concrete, it should be sealed on the second side of the "anti-crack paste"
(3), When the temperature is lower than 5℃.
(4) ,asphalt concrete paving when the vehicle shall not be in the "anti-crack paste" on the ground to turn around.
(5),When the slope is greater than 5%, the width of "crack paste" should not be greater than 330mm. When paving the bottom asphalt concrete, there may be a small amount of slip, should be repaired in time, will not affect the quality of the project.
(6),The total thickness of the paved asphalt concrete should not be less than 6cm.
(7),When the"anti-crack paste" part, the adjacent height difference is greater than 1cm or more potholes, it is necessary to flatten the part and then spread to prevent the "anti-crack paste" in the depression by gravity damage. The leveling material can be leveled with epoxy mortar or asphalt mixture.![factory price earthwork products Anti-Crack Patch_1]()
