The nature of a mineral material, chemical durability of bitumen, its quantity in the mix, compacting load, and other factors strongly influence on the durability of asphalt concrete in the aggressive environment of anti-icing materials. The work covers issues of the effect of anti-icing materials on the change in the surface strength of asphalt concrete.

A promising trend in the technology of road asphalt-concrete mixes production based on the preliminary preparation of granules of asphalt binder concentrate followed by mixing them with hot crushed stone and sand in the asphalt-mixing plant and introduction of additional quantities of bitumen in the mixer and final mixing of the mixture is considered. This technol- ogy makes it possible to improve the homogeneity and quality of the asphalt-concrete mix, strength, water resistance, and operating life of the asphalt-concrete as well as savings of up to 10% of bitumen. The list of technological equipment necessary for realizing the process of preparation of granules of asphalt binder concentrate is presented.
