چکیده مقاله
Crumb rubber modifier CRM is known to have a positive effect on the properties of typical paving asphalts In this paper, the effect of CRM on the performance properties of vacuum bottom, a residuum from the vacuum tower of a crude oil refinery plant, is investigated using the Superpave testing protocol Initial results show that rubber modification increases viscosity, enhances high service temperature, and expands intermediate service temperature range as defined in performance grade superpave specifications The effect of this modification on low service temperature is positive, but less pronounced compared to high and intermediate service temperatures
