Asphalt overlay can be installed between 1 – 2 ½ inches. Tack emulsion is first added as binding agent, asphalt is spread and properly compacted.
Asphalt Overlay FAQ’s
What is an asphalt overlay, and when is it needed?
An asphalt overlay involves applying a new layer of asphalt over an existing pavement surface. It is typically needed when the existing asphalt has moderate to severe surface distress, such as cracks, potholes, or rutting, but the underlying structure is still sound. This process helps improve the pavement’s appearance, structural integrity, and longevity.
How is the condition of the existing pavement assessed before an overlay?
Before an asphalt overlay, a thorough assessment is conducted to evaluate the condition of the existing pavement. This assessment includes identifying any structural issues, analyzing the extent of surface distress, and ensuring proper drainage. This evaluation helps determine whether an overlay is a suitable solution or if more extensive repairs or reconstruction are necessary.
What is the difference between an asphalt overlay and complete pavement reconstruction?
While an asphalt overlay involves adding a new layer of asphalt to an existing surface, complete pavement reconstruction involves removing the existing pavement entirely and rebuilding it from the base up. Overlays are suitable when the underlying structure is in good condition, whereas reconstruction is necessary when there are significant structural issues.
How long does it take for an asphalt overlay to cure, and when can the pavement be reopened to traffic?
The curing time for an asphalt overlay depends on various factors, including weather conditions and the type of asphalt mix used. Our estimators will be able to give you a timeline for your project.
