A composite compression molded article is formed from a composition comprising: a) 60 to 97%, preferably 75 to 90%, by weight of rubber particles of a varied size distribution in the range of 5 to 30 mesh, b) 3 to 20%, preferably 5 to 12%, by weight, of a polymerizable material, said polymerizable m
A composite compression molded article is formed from a composition comprising: a) 60 to 97%, preferably 75 to 90%, by weight of rubber particles of a varied size distribution in the range of 5 to 30 mesh, b) 3 to 20%, preferably 5 to 12%, by weight, of a polymerizable material, said polymerizable material being non-reactive with said rubber particles, and polymerizing to form a matrix surrounding said rubber particles, and c) 0 to 20%, preferably 5 to 13%, by weight, of reinforcing fibres, said fibres being non-reactive with said polymerizable material; the article can particularly be formed as a gasket or adjustment unit which absorbs mechanical vibrations transmitted through a metal component thereby protecting an adjacent concrete component against fracture caused by such vibrations; other articles may also be produced including dock wedges, wheel chocks, speed bumps, delineator bases, anti-vibration pads, manhole and catch basin adjustment risers and portable temporary road or path surface members for use on construction sites to facilitate passage over, and protection of, ground cables and conduits on the site.

[ I claim:] [1.] A compression molded article in the form of an adjustment unit or gasket adapted for insertion between a concrete riser exposed to mechanical vibrations and a metal component which transmits mechanical vibrations, comprising in weight %, 75 to 90% of rubber particles of varied size
[ I claim:] [1.] A compression molded article in the form of an adjustment unit or gasket adapted for insertion between a concrete riser exposed to mechanical vibrations and a metal component which transmits mechanical vibrations, comprising in weight %, 75 to 90% of rubber particles of varied size distribution in the range of 5 to 30 mesh, 5 to 12% of a polymer matrix, and 5 to 13% of reinforcing fibres, said rubber particles and reinforcing fibres being distributed throughout, and surrounded by, said matrix, wherein said rubber particles are selected from rubber crumb, buffings from vehicle tires and mixtures thereof.
