Crack sealing is an essential component of your Pavement Management Program
Property managers and owners need to be aware that not all crack sealing services are the same. Crack sealing can be divided into two different types:
- Blow and Crack Filling: Blow and fill involves blowing out debris from cracks with backpack blowers or compressed air, then topical sealing of the pavement cracks.
- Rout and Seal Crack Sealing: Suitable cracks are routed with special pavement routing equipment to a width of 3/4″ wide and 1/2″–3/4″ deep. This process allows for a reservoir of rubberized crack sealer that facilitates expansion and contraction of the crack both horizontally and vertically. While cone filling of the rout is the standard process of installing the sealant, our crack sealing services use the superior method of overbanding, wherein the crack is overfilled and the sealant spreads onto the pavement around the crack on approximately 3/4″ of either side of the rout. This rout and sealing method, combined with the overbanding method, produces a crack-sealed joint with an extremely low failure rate and a serviceable life of between five and 10 years.
Preserving your pavement for the long run is our goal.
Hot rubberized crack sealant is a blend of asphalt and polymers that is heated to approximately 400°F in specialized oil-jacketed melting kettles. The molten rubberized asphalt liquid is then applied into cracks in asphalt pavement, providing a moisture-proof resilient barrier as the material cools. The material is supplied in 25 to 30 lb. solid blocks that are added to melters and heated.
