Impact of Rubber Modifier on the Rheological Properties of Asphalt

Abstract:

Using crumb rubber to modify asphalt binder can not only improve the binder properties, but also shows environmental and economical advantages. To evaluate the function of the RM modifier in binders, physical properties and rheological properties were investigated. Specifically, the high and low temperature sweep methods was used to investigate influence that the RM on rheological properties of binders. Results showed that binder modification using the RM produces significant increase in both physical properties and rheological properties. Consequently, enhanced resistance to permanent deformation, increased low-temperature cracking and reduced temperature sensitivity can be expected in RM binder.
