SULFUR PAVING MATERIAL BEGINS ROAD TEST

The Southwest Research Institute (San Antonio) completed installation of an 800-foot-long test pavement using Sulphlex plasticized sulfur binders. Tests will be conducted to determine such characteristics as skid resistance, deflection, voids, resilient modulus, smoothness and texture. Sulphlex binders are made by reacting elemental sulfur with chemical modifiers at high temperature. These binders, which represent a family of materials involving 10 or 15 different chemicals, can be made to provide rigid, flexible or intermediate type pavements. The test pavement utilized 3 binder formulations that varied in color from brown for rigid material to black for flexible. The institute projects a materials cost of $70 per ton for the brown, rigid formulation, although actual cost, buying in 55-gal-drum was $131. Although the brown formulation provides a paving similar in rigidity to concrete it does not require construction methods such as forms. It can be installed like asphalt paving, since only over time does it become hard.
