Abstract. Road constructions are most relevant. This article provides data on the improvement of the properties of road construction materials, including those added to the soil: stabilized soil and adhesive asphalt concrete. Because of the impact of the above-mentioned additives, the accumulation of residual deformations in the structural layers of road products are reduced.

The analysis of the market of the Russian Federation, which resulted in the identification of the following most preferred options for additives for research: ANT for soil stabilization and Amdor-10 and DAD-1 mark C for asphalt concrete. For asphalt concrete, several additivies were considered, since this is the most important structural layer in road pavement, perceiving the load from passing vehicles.

This article provides comparative tables and graphs, which provide data on changes in the physic-mechanical properties of materials (soils and asphalt concrete) as a result of the application of the above additives. All tests were performed in accordance with the current regulatory documentation, and all the necessary requirements for the test materials were met.

Were also obtained materials for testing. With the help of this device the possibility of resisting the accumulation of residual deformations is estimated. There is an imitation of situations in which materials are in real road.

As a result, data were obtained that the use of stabilizing additives for soil and adhesive fabric reduces the accumulation of residual deformations and, as a result, increases the turnaround time between repairs.
