How well does your parking lot drain now? How will this be affected by a new layer of asphalt? As a general rule an asphalt parking lot should have a minimum slope of 1% for water to drain properly. Why is edge milling prior to resurfacing important? Proper drainage conditions are extremely important to consider when resurfacing your pavement.
Rubber tire traffic will not damage new asphalt but care should be taken to avoid sharp turns, such as turning the wheels on an unmoving vehicle. How long before traffic is permitted on a newly resurfaced lot? At least a day.On average, however, with proper routine maintenance a newly reconstructed parking lot or road can last from 15-25 years. How long should completely reconstructed pavement last? This again is dependent on many factors as outlines above for resurfacing.An average pavement overlay lifespan can be from 8-15 years, depending on the above factors. Factors that determine pavement lifespan include weather patterns, the harshness of winter (freeze-thaw cycles), how many heavy trucks use the pavement in question, the thickness of the new asphalt layer, the exact condition of the subgrade prior to resurfacing and how well the new surface is taken care of through routine maintenance. How long should newly resurfaced pavement last? That depends on many factors as no two paving projects are identical.When should pavement be reconstructed? When there is extensive damage or alligator cracks, it is more effective and cost-efficient to completely reconstruct than to do an overlay.The condition of the subgrade can be tested through core-testing when there is any concern or question of what shape it is in. When should a parking lot or driveway be resurfaced? When the surface has become heavily oxidized but the base (also known as subgrade) remains in stable condition.Pavement reconstruction is the process of installing both the subgrade asphalt layer as well as the top pavement overlay layer. This new layer is generally 1.5 – 2 inch in depth. What is resurfacing and what is reconstruction? Pavement resurfacing (also known as an overlay, asphalt overlay or pavement overlay) is the process of installing a new layer of asphalt over the existing pavement.
Let’s take a look at some of the most common questions asked. Having the right answers can help you make informed, empowered decisions regarding you pavement. What is reconstruction? What is an overlay? How do I know what I need and how much can I expect to pay? If you are considering new pavement, you undoubtedly have a lot of questions.
