Materials used for patching vary with the asphalt damage. A contractor may use hot mix asphalt, asphalt emulsion mixes, or proprietary patching mixes with unique blends. The contractor will then determine the patching technique and the material required by evaluating the extent of damage to the asphalt pavement. The following are a few patching techniques used for repairing crevices or fissures.
- Throw and Roll – Although temporary, throw, and roll is a very effective patching technique in emergencies. It involves the use of liquid asphalt that is filled into the damaged area and is rolled over. The liquid is applied to the compromised section in layers. It then solidifies over time from exposure to air.
- Semi-permanent patches – It lasts longer than the throw and roll technique. However, it does require a complete surface preparation. Water, debris, chemicals, and contaminants are removed with a vacuum or an air compressor. The defected region is then cut with hand tools or power equipment. The pothole or the crevice is then filled with the patching mix and rolled over.
- Spray-injection – This method is generally preferred to overthrow and roll, and involves the use of truck-mounted equipment. Contractors extract water and debris out of the fault, and inject emulsified liquid and aggregator into it. The high-pressure injection eliminates the requirement for compaction. The method is valid under adverse circumstances.
