A Laboratory Evaluation of Sulphur Extended Asphalt Paving Materials
Of all the sulphur-based paving systems being researched, the sulphur extended asphalt (SEA) mix is the closest to practical implementation. Although a considerable number of field trials in North America have demonstrated the full-scale construction viability of the SEA mixtures, only a limited amount of research work has been reported on the engineering properties of these mixtures over a wide range of service temperatures and their susceptibility to moisture-induced damage. The data obtained in this rather extensive study of the SEA mixtures indicates that at -12C and lower temperaturess, the mix stiffness modulus is not affected when the sulphur (up to 40 percent) is substituted for asphalt. The use of 50/50 (sulphur-asphalt ratio by weight) SEA mix may not be advantageous for thin overlays, it appears to be promising for base courses. The gravel mix was found to be susceptible to moisture-induced damage when the SEA binders were used.
