The authors have proven that sulphur-modified asphalts can be efficiently applied in road building. The authors’ conclusions are based on the analysis of their laboratory research findings.In the article, the authors provide their methodology for design of the sulphur-modified asphalt concrete. The core point of the methodology proposed by the authors consists in the equality of volumes of the oil bitumen in the benchmark composition of the asphalt concrete and in the composite binder containing the bitumen and sulphur modifier.The authors have also analyzed the economic efficiency of modifying the bitumen by the sulphur modifier. The analysis is based on identification of difference between the value of the sulphur modifier that contains the emission neutralization agent instead of the oil bitumen, en expensive component of the asphalt concrete.

A resistance to rutting research of sulphur-extended asphalt with various content of sulphur was performed using modern methods of rutting tests which imitate real conditions of a pavement functioning. It was found that the resistance of sulphur-extended asphalt to rutting is much higher than that of traditional asphaltic concretes. Moreover, increasing the sulphur content results in the increment of this indicator. It was found that the asphaltic concrete resistance to shear can not be truly defined by use of the methods of the existing GOST 12801-98.
