ABSTRACT:
This invention relates to a method of manufacturing a homogeneous solid rubber vehicular barrier, comprising the steps of: mixing and knead melting a mixture of: 80 to 90 percent by weight particles of recycled waste rubber; 10 to 20 percent by weight virgin rubber; and an accelerator composition; forming the mixture in a mould to a selected barrier configuration thus forming a barrier; curing the mixture within the mould at a temperature of 250 .degree. to 450.degree. C. at a pressure of 500 to 1000 psi for a period of time from 1.5 to 7.5 hours; and removing the cured barrier from the mould. A homogeneous moulded solid rubber vehicular barrier, is thereby formed of 80 to 90 percent by weight particles of recycled waste rubber in a matrix of 10 to 20 percent by weight virgin rubber. The completed barrier has a finished outer surface of cured uncontaminated rubber, and has a Shore hardness of between 65 and 70.
