Abstract:

A comprehensive laboratory testing program was conducted as a part of an engineering evaluation of sulphur-asphalt paving mixtures. The purpose was to see (a) if sulphur-asphalt mixtures have better engineering properties than similar conventional asphalt mixtures and (b) what effects various sulphur-asphalt mixture variables and testing variables produce. Static and repeated load indirect tensile tests were used to evaluate these engineering properties: fatigue life, resilient modulus of elasticity, and tensile strength. The major factors evaluated were asphalt consistency in terms of penetration, type of asphalt in terms of temperature susceptibility, binder content, sulphur-asphalt ratio, stress level, and test temperature. The results indicated that sulpuur asphalt mixtures exhibit significantly better engineering properties, in terms of the above three, than comparable asphalt mixutes. All these engineering properties were significantly improved by the use of up to 50 percent sulphur. In addition, using sulphur-asphalt binders can improve the stiffness and fatigue characteristics of softer asphalts. Additional field and laboratory work to verify potential economic and structural benefits of using sulphur-asphalt mixtures is recommended. /Author/
