RESEARCH OF INFLUENCE OF ADHESION ADDITION "ADGEZOL-6" ON QUALITY OF BITUMEN COUPLING WITH THE AGGREGATE SURFACE
The analysis of problem of insufficient water resistance and frostresistance of asphalt pavements with the use of ordinary bitumen was done. The necessity of modification of bitumens is set by adhesion additions with the purpose of increase of coupling of astringent with a surface mineral material. Change of quality of coupling of bitumen with the surface of granite aggregate at introduction of the adhesion additive «Adgezol-6» is investigated. It is established that introduction of the bituminous additive «Adgezol6» improves the adhesion properties initial bituminous binder without the considerable change of its qualitative characteristics, at that the modified astringent conforms to the requirements produced to the initial brand of bitumen.
