Crack Sealing on the pavement surface

 


Crack sealing is a method in which hot sealant is applied to working cracks to prevent water intrusion.Crack seal products are used to fill individual pavement cracks to prevent entry of water or other non-compressible substances such as sand, dirt, rocks or weeds. Crack sealant is typically used on early stage longitudinal cracks, transverse cracks, reflection cracks and block cracks. Fatigue cracks are most often too extensive to warrant filling with crack sealer; they usually require an area treatment such as a patch or reconstruction. Crack filler material is typically some form of rubberized asphalt or sand slurry.


In every crack seal estimate, Asphalt Driveway includes routing, a process performed before cracks are sealed. Routing is done with a piece of equipment that expands all cracks to ¼” wide, which creates a reservoir for the rubberized crack sealant to sit in. Next, crews clean out the cracks to allow the best adhesion possible. Finally, rubber is installed into the reservoirs that have been created by the routing process.The method described above ensures the rubber will fully penetrate the crack and adhere to the existing pavement. It helps create a truly waterproof seal to better prevent leaking, as opposed to placing rubber directly into the existing, non-routed cracks. The process uses compressed air and a high-pressure blow pipe to remove dirt, debris, and water from existing cracks. A kettle heats the crack sealing compound, which is then delivered to the pavement surface through a pressure hose line and applicator shoe. The shoe width and sealer overbanding area are two to four inches wide. When traffic requires immediate use of the roadway, a boiler slag aggregate may be broadcast over the crack seal compound to prevent sealer pickup.

Crack sealing works well in tandem with patching when considering a maintenance plan. Correcting large-scale damage with patching before fixing small cracks with crack sealing is what our team at Asphalt Driveway recommends every owner does each spring to help protect pavement from more extensive damage.
