Abstract
A composite paving block formed from desired proportions of asphalt, plastic such as polyethylene or phenolic resin, elastomeric material such as rubber or polyvinylchloride, and fibre material such as nylon or rayon, is disclosed. Recycled or reclaimed materials such as reclaimed asphalt, recycled polyethylene bottles, and recycled tires may be used. The materials are heated and blended together into a relatively uniform mixture of composite material. The composite material is further heated and is then molded into individual paving blocks, which exhibit a property of very high compressive strength.
