The role of automobile roads construction technology and environmentally clean anti-ice materials on the operational properties of the road surface and traffic safety

Abstract

 In the conditions when our country has become a direct neighbor of the European Union, and also aspires to become its full-fledged member, it is necessary to bring the development of all branches of the national economy closer to the European level, first of all, to establish requirements for the use of a wide range of products that would meet European quality standards.

Roads are constantly under load and exposed to the effects of atmospheric phenomena. Climate, meteorological conditions, destructive actions of vehicles are factors that deteriorate the properties of a road as an engineering structure, thereby reducing the efficiency and safety of road traffic.

One of the important factors affecting the safety of road traffic and the speed of movement of road transport is the slipperiness of the surface (low coefficient of adhesion of the car tire to the road surface), which is especially evident in the winter period. As a result, the braking distance increases, the probability of traffic accidents increases.

Important attention should be paid to winter maintenance, as the winter period is quite difficult for the maintenance of roads and the movement of cars, especially in areas with long winters and significant snow deposits.

Winter road maintenance is a complex of measures, including: road protection from avalanches and snowdrifts, snow removal, elimination of winter slipperiness and fight against ice. Therefore, only the timely implementation of the above-mentioned measures can fully ensure the safe and uninterrupted movement of cars in the winter season.

Therefore, the problem of restoring the roughness of the surface on streets and roads in the winter period is quite urgent. At the same time, an important task is the observance of technologies in the construction of road clothing and the use of environmentally friendly anti-icing materials in the fight against slippery road surfaces.

The paper presents the performance and results of experimental studies of the adhesion of stone material to the icy road surface, and the optimal heating temperature of granite and basalt sifting, under the condition of different ambient temperatures, is established.
