QUALITY INDICATORS OF ALTERNATIVE ROAD BITUMEN
Journal Title: International scientific journal Science and Innovation - Year 2024, Vol 3, Issue 9
Abstract
The article discusses the process of obtaining alternative road bitumen with high adhesion properties using a thermal oxidation experimental device based on gossypol resin, oil sludge, and diethanolamine waste. The results of "passive" adhesion of alternative road bitumen to mineral materials in the preparation of A-type asphalt mixture and the parameters of the limit angle of wetting were obtained. Then it was compared with road bitumen obtained from standard oil. The best indicator was the adhesion of the alternative bitumen on "passive" connection of 96%, and the limiting angle of wetting was 74 degrees. The obtained alternative road bitumen provides an opportunity to produce high-quality asphalt mixture according to the specifications.
