Crack sealing machine can repair the road crack by sealing crack with saving labor resources and low costs. Sealing cracks in pavement before the cracks can develop into potholes is one of the most effective means of maintain paved roads and extending service life for the least cost. It is very important that it can be done properly and promptly. The prompt repair of small asphalt pavement defects will have significant impacts on reducing costs, because once an area is open to the intrusion of water, a larger failure can result. Crack sealing lengthens the life of our nation's streets, highways, parking lots and patios made of asphalt or concrete.
Pavement cracks develop due to expansion and contraction caused by temperature fluctuation. These cracks allow water to penetrate the pavement base and sub-base materials, causing pavement elements to lose structural integrity. Crack sealing machine can finish this work with security and humanized. If not repaired or prevented this cracking effect will grow, leading to deformation of the pavement, pot holes, and ultimately the degradation of asphalt and concrete surfaces.
Cracksealing is preventive maintenance against water from further damaging roads. The use of hot and cold-applied sealants minimizes water penetration, sub-surface ice formation and traffic erosion. Most importantly, crack sealing can lengthens the life of roadways, expressway and highway of asphalt or concrete. According to the survey, with timely preventive crack sealing the useful life of highway pavements can be extended up to 10 years in comparison to other temporary surface treatments such as chip seals, micro paving, thin overlays and slurry seals. As an important advantage, crack sealing can save more money to repair the road and save labor resources.
It must to pay attention to that crack sealing is preventative maintenance, not reconstruction. When a roadway or parking lot is "alligatored" or has incurred more extensive damage than a few cracks, the area must be cut out and replaced or patched.
