Cracks happen. When they do, it’s best to deal with them quickly and efficiently. Treating the affected area with a simple sealant can help prevent serious pavement issues from happening down the road. It’s the most cost-effective way to prevent accelerating deterioration.
Process
After preparing the cracked area, a mixture of asphalt cement and reinforcing fibers is placed in and over the crack. This prevents moisture and incompressible materials from entering the cracks and making them worse.
Benefits
Proactive measure that greatly reduces potholes and other future problems
Critical line of defense against water infiltration
Lowers overall cost of pavement preservation over time
Treated roads can be opened to traffic quickly
Extends road life by 2 to 5 years
Crack Sealing Steps
Begin by choosing roads in need of crack seal, typically roads with a PCI rating from 90-65.
Choose the proper material. Polymer Crumb-Rubber Modified (PCRM) has been tried and tested to provide the best performance over all 4 New England seasons.
Make sure the equipment can keep the material at the specified temperature throughout the entire day.
Set up traffic pattern to keep traffic off the material for approximately 5 minutes.
Utilize a hot air lance and air compressor to clean/blow out and dry all cracks.
For cracks with heavy vegetation, make sure the vegetation is completely cleared from the crack.
Install the crack seal material into the crack void with a pressurized wand and 3” disc.
Immediately after placing the material, install an anti-tracking material over the crack seal material to protect it from traffic pullout.
Consider Crack Seal when
you notice cracks appearing in the pavement surface and want to take preventive action.
“We have used indus’ diverse technology including crack sealing, micro surfacing, and cold in-place recycling. All have produced remarkable results at significant cost savings.”
