Routing and sealing is an accepted industry-wide technique of repairing minor and major cracks in asphalt pavements. Whether you own a residential driveway that’s in disrepair and in need of Crack Sealing applications or a commercial parking lot, this is a highly effective solution that’s used by qualified contractors.
The process involves using a large industrial pavement Crack Router KD-25 machine to grind a channel through the centre of the crack where the Crack Sealant is to be injected. Prior to doing so, field workers must first thoroughly clear out all debris, leaves, sticks and other obstructive objects from the surrounding area that might interfere with the sealing process or inadvertently contaminate the routed channel. It might seem counterproductive to grind a deep channel into a crack pavement area, but this practice is actually highly practical. It creates more room for a larger amount of sealant to be placed into the crack, strengthening the structural foundation of ground beneath and preventing internal cracking or erosion.
By routing cracks before completely sealing them, contractors get the upper hand over the damaged asphalt. This process helps them establish a strong base with which the Crack Sealant can easily form a long-lasting and secure bond. That’s how professional contractors, like Shanghai DOAN Machinery Pavement Maintenance, are able to confidently offer customers a minimum three-year guarantee on asphalt crack repairs and ensure at least eight to 10-15 years of service for asphalt that’s two to 10 years old. They can even offer explicit and flexible application formats depending on the specifications of the crack, ranging from 10mm to 50mm in width.
