Asphalt is referred to as Perpetual Pavement, it can last a lifetime because it's possible to maintain with just milling and overlays, and the deeper portion of the pavement structure remains sound. The New Jersey Turnpike has been in use for 50 years under very heavy traffic, and the chief engineer says he thinks it can last another 50 years.
If you design and care for an asphalt lot correctly, you can actually have a permanent pavement structure. With today's new heavy-duty surface pavements, it is possible for overlays to last more than 15 to 20 years. It just makes sense to design a pavement so that it will serve you long-term, not so that it has to be replaced at a given point in time.Typical Asphalt Overlay Specification
- During the parking lot inspection by a BSM Inspector the area(s) which are determined as the critical area(s) which require overlaying of asphalt will be marked and further investigated by a BSM Engineer if recommended by the Inspector.
- The area(s) are cleaned completely free of debris and will be edged from any vegetation found.
- Over the cleaned surface apply tack coat for proper adhesion of existing asphalt with new asphalt.
- In order to have a smooth surface with out any depressions a leveling course of surface asphalt is installed into the depressions when required.
- The final top layer of asphalt surface course is then installed over the leveling course following the optimum compaction requirements for the best performance of asphalt layer.
- A typical final cross section is shown below
