asphalt, the need to conserve energy, the reduced availability of high-quality aggre-gates, and the dwindling supply of landfi ll space all helped spur advances in the tech-nology and equipment for asphalt pave-ment recycling methods. Projects with re-cycled asphalt pavement (RAP) performed well, which led to the growth of RAP.

Paved Beds Until recently, paved beds used an asphalt or con- crete pavement on top of a porous gravel subbase. Unpaved areas, constructed as sand drains, were placed around the perimeter or down the center of the bed to collect and convey drainage water. The main advantage was the capability to use heavy equipment for sludge removal.

Asphalt Unstabilized Cement-stabilized Figure 1.1. Unstabilized bases have high deflection due to low stiffness, which results in high surface strains and eventual fatigue cracking. The higher stiffness provided by cement-stabilized bases produces lower deflections, resulting in lower surface strains and longer pavement life.
