Almost all roads, driveways, and parking lots in the United States of America use asphalt paving, the chosen pavement material due to its long life of almost 20 years.
Since the longevity of the surface is a top consideration for property owners and managers, asphalt pavements have become an automatic choice. However, maintaining the asphalt pavements is essential to reduce the need for driveway repair Charles County MD.
The materials of construction and the quality of installation also play a crucial role in making the pavements last longer.
The recurring cost of maintenance of asphalt pavements should be a key consideration when creating a budget for constructing asphalt pavements and working out the return on investment. To judge the longevity of asphalt pavements, you must consider the following factors.
The life expectancy of asphalt pavements depends on the extent of traffic load that the surface withstands. Roads usually handle heavier traffic loads than parking lots and driveways, and the load is even lighter for private properties as fewer vehicles and lesser vehicles ply on them.
Besides the number of vehicles, the type of vehicles like cars or trucks determines the amount of load and the resulting force exerted on the pavement’s surface.
Similarly, the extent of footfalls that the surface endures affects its longevity. Higher is the load on the surface, lesser will be the longevity, and it is hard to expect a life of more than ten years for heavy traffic areas.
Quality of Installation
The quality of installation impacts the life of asphalt pavements. The installation quality and workmanship must ensure a good surface finish with perfect edging for minimal chances of the surface breaking down anytime soon.
The installation time or season is also vital because installing asphalt pavements in too much humid climate or a rainy season can be detrimental to the surface quality and increase its susceptibility to damage.
Since asphalt is porous, the moisture in the atmosphere enters inside the surface and weakens it, thereby damaging it soon.
Although asphalt pavements are quite durable, it requires regular maintenance to ensure a smooth and damage-free surface because small holes and cracks can develop at any time.
Delaying the repair of some small holes can soon turn them into potholes that would require costly repairs besides reducing the life of the pavement.
High-quality repair and regular cleaning are a part of the maintenance plan for asphalt pavements that help achieve the stipulated lifespan. Any lapse in maintenance like delaying seal coating can damage the surface prematurely.
Since asphalt pavements have various uses, from parking lots to driveways and roads, the type of material will depend on the purpose of the pavement.
Porous asphalt is the best material that allows water to infiltrate through the surface, move toward the drain, and ensure proper drainage.
For installing perpetual pavement that needs to be highly durable, it is made from several layers of asphalt to withstand heavy loads. The choice of hot-mix or warm-mix asphalt also affects the life of the asphalt paving.
