Florida Asphalt Paving Experts!

Asphalt is strong, durable, and cost effective, which makes it the paving material of choice for parking lots, streets, and driveways.  And with the correct installation and maintenance, your paved asphalt surface will tolerate heavy use and last for many years.

If your facility is between Ft. Lauderdale and West Palm Beach and you have an asphalt paving need, you've come to the right place. National Sealcoating can handle a wide range of asphalt paving projects. Whether your project is new construction or repairing existing asphalt, we have the professionals to handle your job.

New Asphalt Construction
For an entirely new asphalt surface, we first excavate the site to the proper grade and inspect the subgrade for stability.  A stone base is then installed, graded, and compacted to the required thickness and elevation. On top of the base layer, the asphalt mix is installed and compacted as per customer requirements. Finally, all necessary signage and line striping is completed to meet ADA requirements.

Asphalt Replacement
If your parking lot or other asphalt surface has passed its life expectancy or has not been properly it’s could be time to completely remove and replace the old asphalt.  This permits an inspection of the existing base and allows for its repair, if needed.  Once the base has been brought back to optimal condition, the new asphalt can then be installed and compacted.

Pavement Resurfacing
If your asphalt surface is showing signs of surface failure but the base is still intact, choosing an asphalt overlay is an effective solution. Pavement resurfacing typically adds a thickness of about 1.5 inches, before deciding if this is a good option for your application, our professionals will consult with you and evaluate your existing surface.

Asphalt Milling
Because a new asphalt layer can be installed, striped, and the ready for use more quickly than other resurfacing methods, asphalt milling and grinding is a popular option for renewing asphalt surfaces.   The asphalt is milled to a pre-determined depth of one to three inches, the new layer is then installed its place, while the milled asphalt is removed from the site and recycled.

Pavement Overlays
For good-looking and long-lasting resurfacing of parking lots and other paved surfaces, a pavement overlay may be the right choice.  The asphalt surface is repaired, milled and leveled, sprayed with a tack sealant, then covered with a paving fabric. The new asphalt is then installed over the fabric to and compacted thoroughly.

Asphalt Patching
The most common causes of asphalt failure are poor drainage, sun and weather, vehicles of excessive weight, and oils leaked from vehicles. If your asphalt is beginning to deteriorate, we recommend fixing the problem in issue in one of three methods:

  • Remove and Replace - This is the preferred patching method of when the base layer damaged in a relatively small area. With this method, the damaged asphalt is cut out, the stone is removed and the base, inspected. New stone is then installed and compacted to create a stable base. Hot mix asphalt is then added and compacted to match the surrounding elevations.
  • Mill and Replace - With this method, the failing asphalt is milled down to a specific depth, cleaned of debris and a layer of tack is applied to ensure adhesion of new asphalt. A new layer of hot mix asphalt is then installed and rolled to match the thickness of the surrounding asphalt.
  • Asphalt Skin Patching - This is a relatively inexpensive quick fix where the pothole or failed area is cleared of any debris then asphalt is added to the desired thickness and compacted.  As these patches are added to the top of existing asphalt they may not exactly match the elevation of the surrounding asphalt.
