Paving block formed of rubber crumb and a method of manufacturing the same

摘要

A hollow paving block comprises a substantially planar member having a first surface and a second surface opposite the first surface. The first surface of the planar member is a textured surface which functions as a top of the paving block. A side wall extends along and away from a periphery of the second surface of the planar member to define a cavity in the paving block. The side wall has a beveled edge which extends about a mouth of the cavity. At least one protrusion extends along the second surface of the planar member. The paving block is formed in part from crumb rubber and polyolefin.

1. A method of manufacturing an object, the method comprising the steps of:
providing a mixture of crumb rubber and granular polyolefin; feeding the mixture of crumb rubber and granular polyolefin into a barrel and screw; heating the mixture of crumb rubber and granular polyolefin in the barrel to produce a heated mixture of crumb rubber and melted polyolefin; conveying the heated mixture of crumb rubber and melted polyolefin along the barrel towards a nozzle; and injecting the heated mixture of crumb rubber and melted polyolefin through the nozzle into a mold so that melted polyolefin solidifies and forms a matrix about the crumb rubber.
