While asphalt is an excellent choice for many pavement applications, it does require periodic maintenance. Proper and timely maintenance will assure that your asphalt paving is safe for pedestrians and motorists, helps to provide curb appeal and most importantly, has a longer lifespan. Our experienced staff can help you to evaluate your paving situation and develop an appropriate maintenance plan.
Your asphalt paving, as time goes on, will move through phases from light maintenance to repair and eventually, to re-surfacing or replacement. Re-surfacing or reconstruction can be expensive and evaluating proposals can be confusing.
Crack Sealing, Asphalt Patching:
All asphalt endures damage from water, salt, freeze / thaw cycles, sun damage (oxidation, UV rays) and general wear. Typical maintenance repairs are sealing cracks with liquid asphalt to control water penetration, filling potholes with hot patch materials and coating with pavement sealer or an application of slurry seal. These services can usually be completed with minimal disruption to your business.
Cracks left un-sealed let water infiltrate into the sub-grade, softening the underlying soil.
Pictured above is one of our crack sealing crews. A tar kettle is filled with hot liquid asphalt and a wand is used to distribute the material into the cracks after they are blown free of dirt and debris.
This condition is commonly referred to as alligator cracking because of the pattern. It is caused by a soft, unstable or insufficient base which will not support traffic loads. As more surface water absorbs into the base, this situation will become a hazard.
This situation is the result of long term water infiltration. Note the old patch which is also deteriorated and sunken.
Crack filling is the single most effective preventative maintenance procedure
This situation has become hazardous. Now an extensive repair will be required, possibly needing excavated 18” to 24” deep and built back up with a heavy base to support traffic. This could also be an example of a insufficient design or poor construction.

Peter J. Caruso & Sons, Inc., has been installing pavement sealers for over 35 years on all types of projects.
Pavement sealers are recommended for any pavement that is at least 1 year old and could be redone every couple of years. They provide a level of protection for the surface against drying out or oxidizing from the elements. Pavement sealers will not fill cracks of any size or hold any loose areas together. A crack filler, patching or both should be utilized for this. Pavement sealers do provide a nice black uniform surface. Which will extend the life of your pavement also providing your property with curb appeal.
We recommend using an asphalt based sealer or a blended sealer which is a mixture of asphalt based material and coal tar material. We do not recommend a coal tar sealer due to the strength of the chemicals in the material.
