Abstract

Researching results and monitoring urban highways with an upper layer of stone mastic asphalts on blastfurnace slag aggregates with a cuboid-shaped grain are presented in the paper. Crushed stone with such shape of grains is obtained after 3 stages of crushing on a modern domestic and imported crushing and sorting equipment. Relatively high properties of asphalt concretes on the basis of such aggregates have been confirmed by the tests’ results. The optimality criterion and the MathCad software module have been used for the selection of well-graded aggregates. The exploitation of city road surfaces in Lipetsk, used without any intermediate repairs and defects for 13-14 years, has been a practical confirmation of such properties
