Asphalt Paving can be divided into two categories; new pavement construction and overlaying of an existing surface.
New Asphalt Pavement Surface
A new asphalt pavement surface can be installed over a reconstructed lot, an existing gravel lot, or as part of a larger new construction project.
First, the excavation and grading of the area is done to establish the desired grade and drainage. Next, the gravel base is placed and compacted. Finally, a specified asphalt hot mix is installed to provide a finished surface based on the customer’s needs.
Also under this category would be Removal and Replacement of existing asphalt. If the asphalt has deteriorated from a lack of maintenance, overuse, or has reached the end of the designed service life, the old asphalt pavement must be removed and replaced.
Overlay of Existing Surface
When asphalt pavement shows signs of surface deterioration and is still structurally sound, an asphalt overlay is an effective solution.
A standard overlay consists of installing a new layer of asphalt pavement over the existing blacktop surface. The thickness of the new surface is determined by the traffic load and the individual customer’s needs. The existing asphalt surface may include areas in need of repair before the overlay can be installed. This process costs substantially less than removal and replacement and adds curb appeal to your property, while prolonging your pavement life by 7 to 12 years.
