ABSTRACT:
A multi-layer molded composite paving block having a first layer comprising reclaimed asphalt, thermoplastic or thermosetting plastic, monofilament fibre material and elastic material, and a second layer comprising thermoplastic such as polyethylene or thermosetting plastic, and an aggregate material, is disclosed. The first layer comprises about 75% to about 95% of the block while the second layer comprises about 5% to about 25% of the block. The plastic constituent in each of the first and second layers at opposing surfaces thereof are heat and pressure bonded with plastic constituent in the other of the first and second layers, so as to form a securely interlocked structural interface between the first and second layers, so as to thereby form a single integral structure.
