Why do recycled vehicle tires work as a Mechanical Cement cylinder?
Tires treads which interface with the roadway have a composite structure of woven steel belts and polyester chord reinforcing, all of which is embedded in a rubber matrix. Auto tires are designed to withstand road hazards and operate at a maximum air pressure of approximately 44 psi. Because of these engineering material characteristics the tire-tread cylinder has the necessary circumferential tensile strength to be used in support of the lateral pressures generated by civil engineering dead and live loads.
