Since the mid-1980s, polymer-modified asphalt concrete mixtures have been widely used to minimize rutting failures of flexible pavements. This research investigates the permanent deformation behavior of unmodified asphalt concrete mixtures as compared to the behavior of asphalt concrete mixtures modified with polyethylene.
Literature on HP-modified asphalt mixtures was identified by searching various databases related to transportation engineering such as the Transport Research International Documentation TRID database. The identified literature was then reviewed to identify what studies have been published with respect to HP-modified asphalt mixtures.
In particular, there are few studies focusing on the fatigue cracking performance of polymer modified asphalt mixture containing RAP materials. As the polymer modified asphalt mixtures are usually used in surface course in China, it is necessary to study the effect of RAP on the fatigue performance of surface course mixtures. 2. Objectives
The scope of the study is to evaluate the laboratory performance of two asphalt mixtures; one modified with SBS polymer and the second modified with a polymer from Honeywell. Both asphalt binder and mixture properties are proposed to be evaluated in the study.
Fourteen reclaimed asphalt pavement RAP mixtures designed with different combinations of RAP sources, contents up to 40% and mixture conditioning levels were evaluated to determine the maximum allowable amount of RAP material in surface courses without jeopardising pavement cracking performance. Extracted RAP binder was blended with virgin polymer-modified asphalt PMA binder

Currently, the most used polymer for asphalt binder modification is the thermoplastic elastomer styrene butadiene styrene SBS and aromatic oil is commonly added to the mixtures to improve their compatibly. This paper proposes the use of oil shale from sedimentary rock as a compatibilizer agent for polymer-modified asphalt binder PMB.

Putman, Committee Chair Dr. Prasad R. Rangaraju Dr. C. Hsein Juang
The Marshall stability and resilient modulus of mixtures prepared with crumb rubber-modified mixtures were increased on average by 30 and 43%, respectively, as compared to the control mixtures, whereas the permanent deformation of the crumb rubber-modified mixtures was improved on average by 12% in contrast to the control mixtures.
