Asphalt Repairs and Patching for Your Home or Business.

There are several asphalt repair and patching techniques that may be used for filling cracks, pothole repairs in roads, pavements, parking lots, playgrounds, tennis courts, etc. in Maryland. When done the right way, asphalt repair and patching helps prevent further deterioration and avoid huge repair expenses. Materials used may range from hot mix asphalt, to asphalt emulsion mixes and proprietary patching mixes with special blends. Your local asphalt paving contractors at All County Paving & Sealcoating will determine the proper asphalt patching technique and material based on the extent of damage to be repaired.

Here are some of commonly-used asphalt repair methods by your local asphalt paving contractors in Maryland:

Throw-and-roll: This is a temporary patching technique in which liquid asphalt is filled into a hole and then rolled over. It is typically done in winter or adverse weather conditions when a “quick fix” or emergency patch is required. It may be applied in layers and starts to solidify as it reacts with air.

Semi-permanent patches: A longer-lasting solution, this method requires proper surface preparation. Water and debris are first removed with the help of a broom or air compressor after which the area to be patched is cut back with a hand tool or power equipment. The prepared hole is then filled with the patching mix and compacted with a roller.

Spray injection method: In this method, special truck-mounted equipment is used to first blow out water and debris from the crack or pothole, after which aggregate and emulsion will be injected into it. Since the injection is done at high-pressure, no compaction is required. This asphalt patching technique may be ideal in adverse conditions and is often preferred to the temporary throw-and-roll method.

Full-depth patching: Considered a permanent repair method, this technique involves excavating the patching area to the depth of 4 inches or more and extending at least one foot into the surrounding area in order to provider firmer support. A tack coat is applied prior to the asphalt mix followed by a backfill for proper bonding.

Many states have specific guidelines for producing patching materials; so make sure your local asphalt paving contractor, if not us, is aware and performs the job in compliance.
