The present invention is directed to a heavy duty pavement structure comprising an open-graded asphalt layer fortified with a non-segregating grout mixture. The heavy duty pavement structure is made through the steps including forming an open-graded asphalt layer and then fortifying the layer with a non-segregating grout mixture that includes a predetermined amount of portland cement, sand and cement binder system.

Method of making and use of a heavy duty pavement structure

The present invention is directed to a waste or environmental containment system that includes modified asphalt specifically designed for containment, and a system of installation that provides a seamless cap over the area to be contained. The modified asphalt of the present invention has a permeability less than 1&#xd7;10cm/sec and an air void content less than 3 percent. The system of installation includes joint designs that meet the same parameters as the modified asphalt mat to provide a seamless containment cap or liner to contain hazardous wastes at RCRA, Superfund sites, waste sites and environmental containment areas.

A testing system for determining the water sensitivity of a compacted asphalt concrete specimen under various conditions isolates the specimen on a test stand in an environmental cabinet by an impervious shroud and end platens connected to an external fluid circulating system. The specimen is loaded via a load cell by a pulsating actuator and a transducer on the specimen measures axial deformation. Data is transferred from the load cell and transducer to a micro-computer system for analysis.

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.
