Asphalt Crack Sealing


Asphalt Crack Sealing also known as “Route and Seal” Process is a localized treatment that is used to prevent water and debris from entering the sub-grade layers. Hot rubberized asphalt crack sealer are applied to the cracks which properly seals the pavement and help to extend the lifespan of the pavement. Crack sealing ensures that enough sealer is applied between the cracks so that it will stretch when asphalt expands and contracts. The hot rubberized crack sealer is heated and applied at 350 degrees F, and bonds to the walls of the crack and over bands on top creating an air tight seal.

Water is the most destructive element to asphalt.

As part of a pavement maintenance system, crack sealing can significantly reduce pavement deterioration by preventing water penetration into the base and sub base layers.

Crack sealing will not improve initial asphalt readability; however the benefits are realized in three to five years when it becomes quite obvious that the asphalt has not deteriorated any further.

At a time when manpower is shrinking along with the funds to support road maintenance crack sealing stands out as an economical maintenance technique. The overall success of pavement maintenance programs that include crack sealing, combined with the generally low cost, make crack sealing a highly desired technique by successful property managers and municipalities. Crack sealing provides the most cost-effective use of dollars over time compared to other pavement maintenance techniques.

Crack sealing is a proven technique that works.
This is the reason our governments fund crack sealing programs every year on our roads, simply because IT WORKS and IT'S COST EFFECTIVE!


Crack Sealing offer cost-effective asphalt crack repair services by surveying the areas to be crack sealed. Once an area is deemed to be a good candidate for crack sealing, the cracks are then cleaned out with an asphalt pavement router.

During this time, the crack fill material is heated inside a kettle to a temperature of 185 °C (365°F) in a special reservoir on site. Once the sealer is melted, the material is poured into the crack fill pots and applied to the required areas. The crack sealer then cools and contracts flush with the pavement, hardening almost instantly back into its rubber form. It is ready to drive on in a couple minutes. This process is also referred to as route and seal.



Alligator cracking is also known as Fatigue or Spider Cracking caused by lack of strength, or compaction of the base or of the subgrade or due to poor drainage system. If the road has alligator cracking, poor sub base drainage or structural damage, crack sealing will not solve the problem. In these cases the damage is too severe. If you try to save pavement with too much cracking, you will be disappointed with your efforts. In which case, repaving is the only alternative.



Transverse cracking are often caused by thermal expansion/contraction that perpendicular runs to the centreline of the pavement. It may also occur as a result of a reflection crack of an underlying layer or bitumen (asphalt binder) hardening. If transverse crack repairs are left untreated for a long period of time, it may cause the surface to be rougher and allow water channelling, penetration, and damage to the pavement base. It may also lead to potentially more expensive repairs in the long run & pavement deterioration.
