ABSTRACT:
A process for forming a building unit from ground motor vehicle tires. The process includes the steps of grinding a number of tires to create a ground tire mixture which includes ground rubber metal strands and fiber pieces. Between 15% and 20% of adhesive comprising asphalt is added to the mixture. The asphalt containing mixture is then placed into a heated mold and subjected to heat and pressure to form a building unit such as a block. The metal may be removed after the grinding step by passing the ground material under a magnet. The thinnest block is strong enough to form a structure and yet pliable enough to permit an insertion or nails or screws.
