Abstract
A storage system for solid waste material has a sloped storage basin with a subgrade covered by a 3-layer liner comprising top and bottom liquid impermeable layers separated by a drainage layer. The top layer drains into a leachate collection site and the drainage layer drains into a secondary collection site for detection of leakage through the top layer. A cap covers solid waste material stored on the liner. The top and bottom layers of the liner, and an upper layer of the cap are preferably dense-graded asphalt cement, and the drainage layer of the liner is preferably open-graded asphalt cement.
