The impact that crushed rubber can have on the quality of bitumen and asphalt concrete

Abstract

The results influence of finale dispersed rubber crumb on the properties bitumen and asphalt concrete are presented in the study. The parameters of the optimal regime of bitumen and rubber crumb mixing are established. The influence on the rubber crumb mixing with bitumen or added directly in the process of asphalt concrete mixing on the properties of asphalt concrete is studied. The effects that fine rubber has on the properties of petroleum bitumen and asphalt concrete are measured. The best options available for combining bitumen and rubber crumb are given. Moreover, it is also described how and to what extend crumb can influence the quality of rubber-bitumen binder for roads and how rubber-bitumen binder is affected when crump is added to this asphalt mixture. The influence that rubber crumbs have on the quality of bitumen and asphalt concrete. In the study, the influence of crumb on the properties of bitumen and asphalt concrete are shown. The conditions at which a high-quality mixture of bitumen and rubber crumb can be produced. Furthermore, the effects of crumb on the rubber-bitumen binder and the direct introduction of crumb into mixture are thoroughly investigated.
