Influence of ferrous materials on crumb rubber modified asphalts

Abstract:

This research investigated the properties of crumb rubber modified asphalt mixtures, using a wet process. Different size of crumb rubber particles have been used to analyze their effects on modified asphalt. Moreover, two types of crumb rubber were use; one was used without any change (powder 1), while the other one the ferrous material was removed (powder 2). The tests of chemical compositions and microstructure were performed by Scanning electronic microscope (SEM) and optical microscope, respectively. Finally, the results obtained confirm that the rheology of this modified asphalt depends on the chemical compositions of the crumb rubber at low temperatures.
