Determination of Crumb Rubber Content of Asphalt Rubber Binders
The study focused on two new laboratory procedures developed for the determination of crumb rubber content of asphalt rubber binders. The first methodology was on the basis of the comparative analysis of cobalt and antimony content of base bitumen, crumb rubber, and asphalt rubber. The second was on the basis of the analysis of combustion products of asphalt rubber binders and of their components. Investigations were performed on binders prepared in the laboratory or sampled at production plants during pavement rehabilitation works. Obtained results were encouraging because it was found that both procedures were characterized by satisfactory levels of accuracy and precision.
