Routing is done to create a proper reservoir for crackfiling material to adhere to and to ensure that the crackfill stays in place over time. The proper preparation of the existing crack is very important for the adhesion of material and longevity of the repair. Mechanically routing as pictured above cuts, defines and cleans out the respective area that is to receive the hot rubberized crack fill material. The cutting heads on a typical router will widen and deepen the existing crack to a predetermined dimension. This cutting action pulverizes and removes all dirt, stone and debris and also creates a reservoir for the material to "hold' on to and thus much less likely to be pulled out by traffic or snow plowing.

After the routing process the crack is blown free from the dust and debris and all spoils are blown and swept up with a vacuum truck The hot rubberized material is then either injected or applied with "banders" to give a neat uniform finished repair. It is best if the the crack is tilled with material so as to leave the material slightly recessed from the top of the asphalt surface, this gives the crack room to contract and expand without pushing the crackfill material above the surface where it can catch and get pulled or torn out.
