Modern asphalt road maintenance can include thin overlays to extend the life of the roads instead of replacement or thick overlays, as low as 1/2" compared to the traditional 2". This overlay is made of some new material but also quite a bit of recycled asphalt pavement.
These may be combining to keep the demand for new asphalt lower despite continued demand for asphalt roads.
- frik 10y agoBad idea. Some contractors do that. Now they do the same maintainance every year, as the thin asphalt doesn't last long. It's a lot better to properly re-surface asphalt once every 10-15 years with a thicker layer. Just throwing around words like green, recycled asphalt, etc doesn't mean it's a good idea, often it's a rip off, the we have to pay via tax.
- JumpCrisscross 10y ago> thin asphalt doesn't last long Do you have a source for a "thicker layer" of asphalt lasting 10 to 15 times longer than "thin asphalt"? What is the cost difference?
