REMOVE AND REPLACE ASPHALT REPAIRS
Potholes occur when water gets underneath pavement through cracks in the asphalt. When asphalt is sealed and cracks are crackfilled, potholes are kept to a minimum. However, formal repairs may be necessary at times.
Potholes can repaired by a “sawcut, remove and replace” method or infrared method (shown below). Which method used depends on the size and depth of the pothole. In the sawcut method, the area is sawcut outside of the affected area, usually in a square or rectangular pattern. New rock, if needed, is then added, and new full depth asphalt is installed. The area is then compacted with a vibratory roller. Once complete, traffic is then opened up. The asphalt used can be either hot mix or cold mix depending on the season.

INFRARED (SEAMLESS) ASPHALT REPAIRS
Infrared repairs are repairs that produce results like the “sawcut, remove and replace” method, but without the seam, which can turn into a crack as the asphalt shrinks. Infrared asphalt repairs also allow us to lower high areas and raise low (ponding) areas.
C & R Asphalt’s infrared process uses an infrared heating unit that can be rolled over the area. It has gas fired burners and reheats in place asphalt to 300-325 degrees to soften the asphalt into a workable state. The reheating process takes 5-10 minutes. The old damaged asphalt can be raked out from 1”-3” as needed, and then new asphalt can be raked in, leveled and compacted with a vibratory roller or vibratory place. The Infrared asphalt repair can usually can be driven on almost immediately.
During the infrared repair process, the total area is reheated allowing it to bond to the surrounding area creating a “seamless repair”. The same repair can also be completed with the “sawcut, remove and replace” method, but a seam will result, which can be susceptible to water penetration causing possible freeze and thaw damage. This damage could require the repair to be redone or expanded in the following years.
COLD PATCHING ASPHALT REPAIRS
Cold patch asphalt repair is a preferred method for patching potholes because of its ease of use and doesn’t require using any heavy machinery. Cold patch asphalt repairs can be completed with just a shovel and a tamping tool. Cold patching can also be used year round on highways, roads, driveways to repair asphalt damages.
C & R Asphalt uses a premier cold patch product called UPM® Permanent Pavement Repair Materials. UPM is a cold patch asphalt mix that can be used by municipalities, contractors and business owners to fill potholes and repair roads. As a distributor of Unique Paving Materials, C & R Asphalt is a strong proponent of UPM cold mix products and stringent quality control procedures that ensures cold patch asphalt solutions that outlast the surrounding pavement over 90% of the time. They guarantee it!

RAVEL CHECK ASPHALT REPAIR PREVENTION
C & R Asphalt also offers a pavement rejuvenator that extends sealer performance by returning the pavement surface layer to near new chemical and physical condition. Rejuvenators return components to the asphalt surface that are lost through the process of oxidation after sealer is applied to asphalt
C & R Asphalt utilizes RAVEL CHECK, an asphalt based emulsion with penetrating chemistry and asphalt resins designed with LOCK THE ROCK® technology to rejuvenate, preserve and restore asphalt based pavements.
RAVEL CHECK is an asphalt rejuvenation and preservation liquid designed to preserve and restore problem pavement areas. Pavement showing signs of raveling, cold seam failures and oxidation due to weathering, poor construction and snow plows can benefit from a rejuvenator like RAVEL CHECK. Rejuvenators can be applied to asphalt pavements to extend pavement life cycles by preventing further damage. When used properly, rejuvenators can help save roads that are in good condition, prevent early repaving, and prevent further pothole formation.
