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.

Современные методы оценки устойчивости дорожно-строительных материалов к накоплению остаточных деформаций. – Ростов н/Д: Издательский центр ДГТУ, 2016. – 110 с
Summary
В результате воздействия вышеуказанных добавок рассматривается снижение накопления остаточных деформаций в конструктивных слоях дорожных одежд. В данной статье приводятся сравнительные таблицы и графики, в которых указаны данные изменения физико-механических свойств материалов (грунтов и асфальтобетонов) в результате применения вышеуказанных добавок. В качестве представления результатов были построены графики, с помощью которых можно сделать вывод о том, что применение стабилизирующей добавки для грунта земляного полотна и адгезионной для асфальтобетона позволяет снизить накопление остаточных деформаций и, как следствие, увеличить межремонтный срок дорожной одежды. В целях снижения накопления остаточных деформаций рекомендуется применение специальных добавок для улучшения свойств дорожно-строительных материалов. В данной статье рассматриваются способы снижения накопления остаточных деформаций в конструктивных слоях дорожных одежд и в грунте земляного полотна за счет применения стабилизирующих и гидрофобизирующих добавок для грунтов, а также адгезионных добавок в асфальтобетон
