Crack Sealing

To prevent water from further damaging asphalt lots. Sealing buys time and saves money by delaying the expense of major reconstructive pavement work. Water is the most destructive element to our pavements. Filling or sealing pavement cracks to prevent water from entering the base and sub base will extend the pavement life by three to five years. The Polymeric hot-applied sealant is intended to fill the cracks and keep most of the water out of the pavement. When water is kept out, pavement deterioration is slowed.

Crack Routing

Cracks must be free of all dirt, dust and debris. The sealant must have a clean, dry bonding surface. Surface preparation can be accomplished with compressed air and a simple blowpipe. Studies showed there is almost a 40 percent greater chance of sealant success if cracks are routed prior to sealing. Cutting a reservoir above the crack allows adequate sealant expansion and contraction. The reservoir also ensures that the proper amount of sealant penetrates the crack. An operator passes the pavement cutter or router over the crack and cuts a reservoir into the crack. Modern routers can follow even the most random pavement cracks. Once the rout is complete, simply use compressed air (hot or cold) to remove the dust created by the router. Engine-powered steel wire brushes also can be used to clean routed and non-routed cracks. (Note: Older-aged asphalt pavements and thin asphalt pavements may not be suitable for routing.)

Note: Cracks that are routed prior to sealing perform up to three times longer than cracks that were not routed.
