Resurfacing asphalt is a process where new asphalt pavement is placed over the existing surface. This solution is fast and can provide the most economical decision! But there are drawbacks. The worst drawback is that existing cracks will reflect through the new overlay quickly. We recommend and provide a cost-effective alternative to stop the reflective crack called BST. This process can give a useful life comparable to a new asphalt lot at a much lower cost. Paving Professionals will evaluate potential issues with the subgrade or drainage problem occurring under the pavement.
If resurfacing is not the best option, then replacement and subgrade repair must be considered. This would involve:
- Mobilize a milling machine to remove the old asphalt surface.
- Once the old asphalt is removed, a grading crew will adjust manholes and utilities to the required finish grade elevation, so they can obtain the same elevation as the new asphalt.
- Our paver, rollers and other equipment will mobilize and spread the asphalt over the parking lot. Depending on the thickness, more than one layer can be applied.
- Once the pavement has been installed and properly consolidated and enough time has passed for it to solidify, then we place the pavement markings on the new surface.
Replacing the Asphalt Pavement
When removal and replacement is needed, the subgrade must be evaluated and repaired prior to new paving. The biggest advantage of a BST Overlay is that the remaining strength of the existing paving is added to the strength of the new overlay.
