Abstract:

The purpose of this paper is to summarize the results of the first phase of a project to evaluate the effect of Crumb Rubber Modifiers (CRM) produced by different processes on basic rheological, failure, and aging properties of asphalt binders. The study also addressed the high-temperature stability of the asphalt rubbers as well as the aging characteristics of these binders as reflected by the Thin Film Oven Test (TFOT) and Pressure Aging Vessel (PAV) aging procedures. This paper also includes analysis of the effect of high-temperature storage on rheological response at high and intermediate temperatures, the effect of rubber on the properties used for grading using the new Strategic Highway Research Program (SHRP) specifications, and an evaluation of the change in aging characteristics of the selected asphalts as a result of adding the CRM.
