ABSTRACT
The results of researching the influence of ultraviolet irradiation factors, the damp climate of the Black Sea coast and sea water on the physical and mechanical characteristics of asphalt binders made on the basis of bitumen and bitumen- -polymer composites are presented in this article. Medium density, water saturation, compressive strength at the temperature of 50 ±2°C and mass change of asphalt binders were defined. It was found that sea water has a negative effect on the majority of physical and mechanical characteristics of asphalt binders. The compositions of asphalt binders resistant to the impact of climatic factors were found. The optimal composition of asphalt binders was selected. The investigation results can be used in the manufacture of durable road asphalt and waterproofing materials exploited in the climatic conditions of the sea coast and sea water.
