There are numbers of the cracks on the pavement after using the road for a few years. Sealing the crack can not only help the operator save the cost, but also can extend the life of the pavement. Sealing asphalt concrete pavement cracks has a number of benefits--the biggest being that it keeps out water and moisture that can lead to a number of issures, including potholes.
Cracks always occur when ice melts during the freeze -thaw cycle. During the spring and summer, water leaks into potholes and cause the subgrade to wash away. This can lead to cracking as well.
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.
