Abstract
A matrix for aggregate containment and drainage system for road-base construction, or reconstruction--provides by reuse of vehicle tires. Each tire (unit) has one sidewall removed and drain holes provided in the remaining sidewall. A plurality of these units are positioned and fastened together to form a matrix. Each unit open side up, lying flat then receives aggregate construction material. The matrix configuration provides an excellent base for construction, minimizing aggregate loss due to sinking, wash out or lateral movement. A major ecological advantage is the beneficial use of otherwise problem used tires.
Claims17
A road base matrix, comprised of:
- a plurality of automotive tires positioned in a generally planar array with each of said tires comprising a cylindrical crown exhibiting an uppermost circular periphery and a lowermost circular periphery separated by said crown from said uppermost circular periphery, and a first annular sidewall integrally joining said lowermost circular periphery of said crown, each said first annular sidewall disposed upon a porous base underlying the matrix and defining a first central aperture exhibiting a first radial dimension along a plane of said matrix and opening directly to the base, said uppermost circular periphery defining a second and substantially greater radial dimension, and a second annular sidewall integrally joining and extending radially from said uppermost periphery of each of a multiplicity of said crowns, with each of said second annular sidewalls defining a corresponding second central aperture substantially greater in size than said first central aperture;
- and
- a plurality of elongated means extending radially through crowns of adjacent ones of said tires, for joining neighboring ones of said tires together in said matrix.
A road base matrix, comprised of:
- a plurality of automotive tires positioned in a generally planar array with each of said tires comprising:
- a cylindrical crown formed by a continuous web impregnated with a pliant, flexible material, said crown exhibiting an uppermost circular periphery and a lowermost circular periphery separated by said crown from said uppermost circular periphery;
- a first annular sidewall integrally joining said lowermost circular periphery of said crown, said first annular sidewall disposed upon a porous base underlying the matrix with said crown extending upwardly and axially away from said first annular sidewall and defining a first central aperture exhibiting a first radial dimension within a plane of said matrix and opening directly to the base, said first annular sidewall being perforated by an orifice extending through said first annular sidewall to the base, said uppermost circular periphery defining a second central aperture exhibiting a second and substantially greater radial dimension;
- and
- a second annular sidewall integrally joining said uppermost circular periphery of said crown, exhibiting a second radial dimension within said plane substantially less than one-fourth of said first radial dimension;
- said crown, said first annular sidewall and said second annular sidewall forming a singular integrated and monolithic structure;
- and
- a plurality of elongated means extending radially through crowns of adjacent ones of said tires, for joining tangentially neighboring ones of said tires together in said matrix.

- and
- a plurality of elongated means extending radially through said monolithic structure of adjacent ones of said tires, for joining tangentially neighboring ones of said tires together in an ordered array within said matrix.
