Rubber Crumb Modified Bitumen Produced from Crude Oils Residuals of Ukrainian Deposits

Abstract

1 The main regularities of the modification with a rubber crumb for bitumen produced from the residuals of crude oils of Ukrainian deposits have been studied. The thermal stability of the rubber crumb has been examined using the derivatograpgy. The mechanism of bitumen modification with the rubber crumb at low and high temperatures has been established. The influence of technological factors on the main quality indices of modified bitumen has been studied. The changes in the group composition of the original and modified bitumen were found.
