Preventative Road Maintenance
Liquid Asphalt surface treatment, better known as Chip Seal Technology, is the most economical solution for extending the life of road surfaces. When hot mix overlays are not in your budget, chip seals can perform the same function for a fraction of the cost. Depending on the roadway’s needs, we can customize a solution by applying chip seal with various grades of neat or polymer modified asphalt emulsion. Chip Seal can reduce costs per square yard by over 50% and provide a timely solution with production rates of up to 5 miles per day.
A chip seal consists of an application of water-based asphalt emulsion that is applied to the roadbed and “cover stone” (an application of uniformly graded crushed stone) is placed over the asphalt film. The pavement is then rolled and traffic may be restored the same day. Chip seals are a low-temperature, environmentally friendly process that reduces emissions and fumes. We can also combine our emulsions with state-of-the-art polymers that increase durability significantly. Chip seals are recommended for municipal and private roadways with moderate traffic levels up to 2,500 vehicles per day.
Chip seals, as thin lift maintenance pavements, are principally designed to protect the surface of an existing bituminous pavement. The chip seal can seal small cracks in the pavement bridge and protect the surface integrity of the existing pavement, adding at least five years of additional service life for a very small investment in time and money. Ideal candidates are pavements having good geometry and structural integrity (i.e. a good base). Exclusive use of hot mix overlays to extend the life of pavements in this condition is both expensive and unwarranted. The cost of a single chip seal can be as little as 25% of the cost of a traditional hot mix overlay and provides even more savings as compared to the other exotic thin lift pavements.
