In order to keep your asphalt parking lot looking as nice as the day it was first installed, you will have to perform (or better yet, have a professional perform) periodic maintenance. Asphalt maintenance can be categorized into five areas: patch repair, asphalt overlay, inlay, pulverize in place and seal coating.
Patch Repair: This is the most common form of pavement maintenance and involves isolated areas of asphalt. The pavement is cut away from this area and is then replaced with fresh asphalt.
Asphalt Overlay: This affordable method of asphalt maintenance provides a new wearing surface of asphalt over your entire parking lot.
Inlay: This maintenance method is accomplished using milling machine, which removes a specified depth of existing asphalt and allows contractors to restore the parking surface to its pre-inlay elevation.
Pulverize in Place: Just like the Inlay method, Pulverize in Place utilizes a milling machine. But this method actually reduces your parking lot to base-rock-size particles. The resulting product can be graded like new base rock and the roadway reshaped to improve drainage.
Seal Coating: This process seals the asphalt, preventing moisture from penetrating the surface of the pavement and protecting the top layer of asphalt from oxidation and wear.
Seal coat should be applied to new pavement every 6 months to a year. After that, seal coat should be applied every 3-5 years.
