C and R Asphalt Crack Sealing

Crack Sealing

C & R offers Hot Rubber Crack and joint sealing. We have found that cold pours simply can't perform at the same level, although they have come a long way. This process usually goes hand and hand with sealcoating. Generally the pavement is cleaned, crack sealed and sealcoat is applied. We recommend that if a pavement is cracked it be inspected every year. Any new cracks that have formed or old cracks that have reopened should be resealed. Colder temperatures actually promote better crack sealing because the asphalt is contracted opening the crack wider and allowing more hot rubber to flow into the reservoir. Winter months can be good for crack sealing, however you don't want to leave cracks open for freeze and thaw cycles. The intrusion of water into pavement is bad news. Water destroys pavement. It breaks down the rock properties and softens the subgrade (clays and soils) causing eventual pot holes and pavement failures. When water enters a crack and freezes it expands and either causes the asphalt to explode or crack further eventually resulting in a pot hole and further failures.

Most customers agree that black lines of crack fill in a roadway or parking lot are not attractive. They will even look worse than the cracks themselves (unless a fresh coat of sealer is applied for uniform color). However, the alternative of not crack sealing can be devastating economically in the long run.
