Where a routed crack is found to be more than 10% outside the specified rout dimension, geometry, or location, it shall be considered unacceptable and corrected by additional routing.
Where the sealant subsides in the rout by more than 1 mm below the adjacent pavement surface, the surface of the sealant shall be cleaned and topped up.
Where pavements are to be overlaid, if the surface of the sealant is greater than 6mm below the adjacent pavement surface, the surface of the sealant shall be cleaned and topped up.
Where the sealant. 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.
We have spent countless hours developing these machines with tour in house engineer. Our goal was to create a rugged machine that will hold up with the environment that it's working in and at the same time being extremely productive for you.
