Use as maintenance treatment or to prepare a cracked pavement for surface sealing. Structurally sound pavement structure and crack width is between 0.1-1.0inch. When accounted the following situation like alligator, fatigue, reflective, edge and slippaage cracking, it should not use pavement crack sealing. However, when meet the longitudinal, transverse, block cracking, it adviced to crack sealing.
And the most important, the width of a crack may change because of temperature and moisture changes to cause the crack open or close. The sides of a crack may undergo vertical movements under traffic loading. Criteria for "working" cracks: total horizontal movement of a crack over a period of 1 year.
If you have a lot of cracks to seal I recommend that you continuously feed the blocks of crack sealing machine into the hot liquid inside the kettle. The solid cubes will melt faster this way and save you melt down time. As a professional manufacture, Shanghai Doan Machinery Technology Co.,Ltd. understand how important it is to have a reliable equipment to get your crack jobs done professionally.
