The site navigation utilizes arrow, enter, escape, and space bar key commands. Left and right arrows move across top level links and expand / close menus in sub levels. Up and Down arrows will open main level menus and toggle through sub tier links. Enter and space open menus and escape closes them as well. Tab will move on to the next part of the site rather than go through menu items.
Recycled asphalt pavement (RAP) is asphalt paving material recovered from old road beds either by milling or excavation. It includes aggregate, as well as reusable bituminous material. RAP produced by milling can be hauled to the asphalt plant and recycled by adding it directly to virgin hot mix asphalt (HMA). RAP produced by excavation is usually in the form of large chunks, which must be crushed before it can be used at the asphalt plant.
There is a long history of incorporating RAP into new asphalt pavement mix. The use and acceptance of RAP as a sustainable and economical material for quality road building continues to grow. Asphalt is America’s most recycled material.
