The relevance of the work is determined both by the problem of efficient utilization of increasing sulfur industrial discharges and the possibility of using local weak stone materials which are not widely used. It is established that the impregnation of sulfur melts into the pores of crushed stone facilitates the formation of a durable gradient layer with changed properties that resulting in increasing the hardness of grain surfaces and manifestation of hydrophobicity and that in its turn affect the change in operational-technical properties of crushed stone. This, the index of crushability of processed crushed stone reaches the value of 1200, and the water saturation index reduces. The produced material can be used in the bases of road pavement structures as well as in compositions of hot asphalt concrete mixes. Thus, asphalt concretes with processed crushed stone regarding the values of compressive strength and resistance to fatigue exceed the minimal requirements of GOST 9128–2013 set for B type by 1.5–2 times on the average.
