An overlay is a new section of hot mix asphalt, usually 1.5”-2”, placed over the existing pavement surface, often utilizing an interlayer made of specialized fabric and/or fiberglass. This type of rehabilitation is commonly seen on city streets and can be both cost effective and structurally effective on parking lots and private roadways as well. Drainage profiles and the condition of the existing pavement must be considered when planning for an overlay. An overlay IS in fact a new asphalt surface and to most people will have the same appearance of asphalt that has been fully replaced. There are pros and cons, cost implications, and longevity considerations with determining whether an overlay, replacement or a hybrid approach is best. That’s where we can provide guidance.
