Crack Sealing / Route & Seal

What is Crack Sealing?

Crack Sealing also known as “Route & Seal” is the process of routing (cutting out longitudinal cracks with a pavement router) creating a reservoir with clean edges for the hot rubberized crack sealer to properly bond to the pavement. This reservoir is crucial to crack sealing because it 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 overbands on top creating an air tight seal.

Crack Sealing vs Crack Filling?

Don’t be fooled. Know the difference!
Crack Sealing is when eligible cracks are routed, cleaned out, and properly sealed for an air tight seal, preventing water from penetrating the surface.

Crack Filling is when a contractor simply butters over the cracks with sealer. As you can tell in the diagram below, there is very little sealer in the actual crack and it is already opening up in a few days after application.

The Process

Step 1

Eligible cracks to be route and sealed are identified, measured, and marked to be prepared for quotation.

Step 2

All marked cracks are routed using a high torque marathon carbide-tip crack router and blown free and clean of all debris to ensure proper bonding to the pavement.

Step 3

Cracks are then sealed using mobile material applicators with an overbanding strike off shoe to ensure a consistent, neat width of material to fill the routed reservoir and provide surface bonding and long joint life.
