Why Is the Maintenance and Repair of Cracks so Important?

The most important reason you need to maintain and repair the cracks is because you don’t want water to infiltrate under the pavement, which will cause more damage to your driveway or parking lot. Even worse, if water seeps under the asphalt surface, then the water under the asphalt surface will freeze in lower temperature and push the road up. The another reason is because plant will begin growing in cracks. As the roots get bigger, the plant root can actually push the road up, break the pavement surface and even create more damage. And now pavement asphalt filling machine will be your road maintenance expert.

Filling asphalt cracks is not a difficult job, but road crack sealing machine sure will save you money and keep your asphalt pavement surface looking good for many years. Cracks filled with asphalt can stop water and debris from entering the crack, protect the longevity of pavement.

Working Principle of Concrete Shot Blasting Machine:

The centrifugal force and wind force are formed during high-speed rotation of  motor-driven shot blasting wheel. The steel shot or sand is thrown onto the working surface at a high speed and a certain angle, the road surface is rubbed and the residue is removed when the pellet impacting the working road surface. The medium will be rebounded to high-pressure chamber and into air separation system after blasting. In the separation system the dust and other impurity will be separated, clean medium and little dust will return to abrasive storage tank, then enter into shot blasting chamber and recycling, a large amount of dust is absorbed by the connected vacuum cleaner. We can obtain different ejection strengths and different surface treatment effects by controlling and selecting the size, shape and flow rate of the pellets, adjusting and setting the walking speed of the machine.

Working Conditions:

1. Working surface unevenness <10mm; no water accumulation and relatively dry; slope <25°.
