The Federal Department of Transportation obtained five million dollars from Congress on the advice of the National Research Council, to study the best materials and equipment for repairing potholes. This resulted in publication of SHRP-H-348 (Strategic Highway Research Project) under the auspices of the National Academy of Sciences, United States Government, and the American Association of State Highway and Transportation Officials, known as Projects H105 and H106.
Test sections were installed at 22 sites throughout the United States and Canada between March 1991 and February 1992, under the supervision of SHRP representatives. The researchers collected installation and productivity information at each site and periodically evaluated the experimental repairs and treatments for 18 months following installation. As asphalt pavements age and deteriorate, the need for corrective measures to restore safety and ride-ability increases. This not only proves to be expensive, but also costly for ride-ability and pavement lifespan.
The cost most commonly associated with pothole repair is the cost of purchasing material. You need a better performing patch with long-term durability. That patch is Perma-Patch. Choosing Perma-Patch reduces the cost of the initial patching effort and eliminates the need for re-patching. By doing this, you save on overall labor and equipment costs for the entire operation.
