Modification of residual bitumen from Orhovytska oil by Butonal polymeric latexes has been studied. Using such modifiers the softening temperature and bitumen elasticity increase and penetration decreases. The commercial paving bitumen may be produced from the residuals using Butonal polymeric latexes.
The investigation results of type B fine asphalt concrete and its form modified by rapeseed oil epoxide are represented. The efficiency of ERO addition and its positive effect on the physico-mechanical properties of asphalt concrete has been established.
Three commercial road emulsions on the basis of petroleum bitumens differing by their production method (oxidated, distillation and modified bitumens) and Redicote E-11 emulsifier were obtained. The obtained emulsions were used for the production of Slurry Seal and thin-layer road coatings on its basis. The coatings based on modified oxidated bitumen have more advantages compared with those based on oxidated bitumen. The expensive distillation bitumen may be exchanged for modified oxidative one to use it in a Slurry Seal technology.
