【 摘 要 】

Possibilities of activation of disperse mineral powders from the technogenic raw materials of KMA by ultraviolet irradiation are considered in this article. The optimum time of ultraviolet exposure for each material is determined during which the concentration of exchange centers is increased, the rate of rehydration is slowed down and the moisture absorption is significantly reduced. It is shown that both physical and mechanical characteristics, as well as durability of asphalt concrete prepared on the basis of modified mineral powders are significantly increased.
