What is Hot Applied Mastic Patch?

Hot Applied Mastic Patch is hot applied, pourable, aggregate filled, self-adhesive polymer modified asphalt binder with excellent load bearing and skid resistant characteristics.

What does it do; where should I use it and how does it compare to traditional crack sealants & hot mix asphalt?

 

Hot applied mastic patch is used to repair and seal the following:

  • Wide pavement joints or random cracks over 1-1/2” in width- Hot applied mastic patch will fill and seal cracks 1 ½” and wider. When cleaned properly hot applied mastic patch’s adhesiveness will create an excellent bond to the sidewalls of the crack. Traditional crack sealants will not work well in cracks 1 ½” and wider.The crackfiller will fail due to the fact that they are not modified to handle the severe movements. Typically crack sealers do not have aggregate as hot applied mastic patch does. When repairing wide cracks with the hot mix asphalt cut & patch repair method, a joint is cut on each side of the existing crack. Eventually the joint between the existing asphalt and the new patch will open, creating now two cracks rather than just the original one. The mastic patch bonds to the existing pavement so open paving joints do not occur. The cost of the hot mix asphalt repair is usually far greater than hot applied mastic patch due to larger crews, more equipment and additional fuels and time it takes to complete the job.
  • Small to medium sized severely distressed or alligatored pavement areas– Traditional crack sealants have been used to try to seal over these areas but because they do not have aggregate; (as hot applied mastic patch does) these areas will become slippery over time and will be a liability. Installing asphalt over the distressed area does not solve the problem. This is called a skin patch or a thin asphalt overlay. Hot mix asphalt skin patches traditionally do not last a year because hot mix asphalt does not bond as well to the existing asphalt.The patch eventually comes off the area or the cracks underneith reflect through the patch causing it to break up. Hot applied mastic patch will fill and seal the cracks in these areas where hot mix asphalt can not. Hot applied mastic patch can provide many years of service and greatly reduce further deterioration and expensive repairs. Hot mix asphalt repair method should be used on large distressed or alligatored areas and should be excavated and repaved.

  • Filling pot holes. Hot applied mastic patch’s greater ability to bond is the key here, thus sealing out water and a longer lasting repair than hot mix asphalt. Traditional crack sealer can’t be used here. Hot mix asphalt cut & patch would be more due to the large amount of equipment and labor needed to complete the job.

Potholes are trip hazards and harmful to vehicular traffic

  • Leveling approaches to manhole covers to reduce plow damage. Skin hot mix asphalt patch does not work in this situation. Leveling approaches to manhole covers are ideal for mastic patch.

Manhole covers like this are a major liability

Why a mastic patch?

  1. Hot applied mastic patch is an extremely economic alternative product when used in proper repair situations.
  2. It is a quick repair with limited down time, 30-60 minutes total on average.
  3. Its ability to be provide a skid resistant surface, flexibility and load bearing capabilities make Hot applied mastic patching a truly versatile repair product for asphalt needs.

Catch Basin Repairs

Catch basins are usually an out of sight, out of mind portion of the parking lot until sinkholes develop in your asphalt causing major problems and liability hazards. Catch Basins are an important part to your parking lot structure. Catch basin repairs can range from a simple rebuild of your existing man hole to a complete replacement of the entire drainage system.

Yearly inspections and evaluations of your catch basins, along with timely repairs will prevent costly future repairs. Replacement of a few blocks or bricks, some mortar or repairing a bent grate will keep your parking lot drainage system working properly.

Why do catch basins fail over time? Blocks and bricks used to construct your catch basins begin to fail and deteriorate. This is mainly due to water intrusion through cracks in the asphalt surrounding the catch basin. The water will undermine and erode the base materials which support your asphalt. Winters in New England are particularly tough on manholes and catch basins. If salt is used in the winter time the water will carry the salt into the basin and will deteriorate the mortar that holds the bricks or blocks together causing them to become loose and fall into the basin. Once the blocks and bricks are deteriorated, the main structure is no longer secured.  Cars driving, parking over them or even snowplows hitting them will create more stress on the loose bricks or blocks and grates.  This makes the entire top structure sink, creating more liabilities. If the surrounding asphalt or concrete around your catch basin is cracked or heaved, it may be time to get your manhole and catch basin repair done.

A good contractor can quickly and efficiently barricade the damaged area without disrupting the flow of traffic in your parking lot. Will remove and replace all deteriorated blocks, bricks and mortar, or pre cast insert, re-level the existing grate and replace the failed concrete or asphalt, giving you a structurally sound catch basin. Once the surrounding asphalt or concrete apron is replaced your catch basin will be back to original engineered specifications.
