ABSTRACT:
The present invention relates to a process for manufacturing a construction material by mixing a cementitious material, rubber bits and water. It also extends to a construction material comprising cured cementitious material and rubber bits in which the rubber bits are bonded together in a porous and permeable matrix by the cementitious material. An elastic binding material improves the physical properties of the construction material. The construction material can be cast in place or formed into blocks for transport to a construction site.
