【 摘 要 】

The article studies the effect of ultraviolet radiation, salt fog, variable humidity, and sea water of the Black Sea coast of Krasnodar region near the village of Abrau-Durso on the basic physical and mechanical properties of asphalt: the average density, water saturation, tensile strength at 122 °F, 68 °F and 32 °F, on the waterproofing quality of asphalt concrete. The samples were exhibited on a pier and in the soil on the coast of the Black Sea, in the sea water and in the air 400 m away from the sea. Test specimens were manufactured in accordance with Russian State Standard GOST 12801-98. Test duration was 240 days. It is found out that sea water has a negative effect on the majority of physical and mechanical characteristics of asphalt concrete. The authors found the compositions of asphalt concrete with increased resistance to the influence of climatic factors. Higher resistance is achieved in the case of dense asphaltic concrete ballast.
