Remove and Replace Patching
Areas that have significant cracking and/or uneven surface due to subgrade failure must be removed and replaced to keep the effected area from spreading. This method of repair is the most permanent, aesthetically pleasing type of patching, but it can be more expensive. The failed asphalt area will be sawcut and existing asphalt removed. Roadbase will re-compacted (added if needed) and a tack coat applied to the asphalt edge for bonding. New asphalt will be placed and compacted.
Skin patching attempts to bridge over defects by adding a thin layer of compacted asphalt to the problem area. This application is typically used to repair potholes and settled areas around manholes or catch basins. It is considered a temporary (1-3 year), inexpensive fix. Skin patches will alter the smoothness of your asphalt.
The failed asphalt area will be cleaned of all loose debris. A tack coat will be applied to the existing asphalt for bonding. New asphalt will be placed and compacted.
As the seasons change, asphalt expands and contracts. This movement causes cracks. If cracks are not sealed, they will allow water to flow through the asphalt to the base. The base will become saturated and will not be able to support the asphalt above. More cracks will form allowing more water to enter the base. Without maintenance, this cycle will destroy your asphalt. Crack seal seals cracks from water. Crack seal is made of rubberzed asphalt which expands and contracts with the crack. Crack sealing is one of the most important things you can do to extend the life of your asphalt.
Seal coat provides a protective barrier for the surface of your asphalt. It stops water from petetrating the surface, protects from the sun’s ultraviolet rays (oxidation), resists oil, gas and salt, and provides an aesthetically pleasing surface. Seal coat is a mixture of oil, water, and slate. When applied, the water evaporates leaving the oil and slate as the new wear surface. When covered with a dark black sealant, pavement looks and wears like new. Seal coating projects a positive image of the company, facility, or residential complex.
Seal coating can save real dollars for pavement owners. Unsealed pavements will require repairs starting within the second year and could require a one-inch overlay as often as every seven years. Cost savings will be a substantial 65% if the pavement is maintained regularly. Estimated savings for a 10,000-square yard asphalt pavement are $127,000 over 15 years.” – National Pavement Contractors Association
