MARC presents Latest Research Findings at the 93rd Annual Transportation Research Board Meeting
Participants at the 93rd Annual Transportation Research Board Meeting on Jan 11-16 in Washington D.C. became familiar with the MARC's latest research findings and developments through a number of presentations on cold mix asphalt, oil and extender additives, image analysis, computational modeling, and relating mix design properties to pavement surface texture. Furthermore, recent advancements and future research trends on the topic of performance-based mix design was presented to the TRB AFK30 committee on "Characteristics of Nonasphalt Components of Asphalt Paving Mixtures" by Dr. Nima Roohi; while Dr. Hassan Tabatabaee presented recent advancement in computational modeling of thermal cracking and low temperature damage in asphalt materials to the TRB AFK50 sub-committee on "Advanced Models to Understand Behavior and Performance of Asphalt Mixtures".

MARC Researchers Receive Walter J. Emmons Award
A recent publication by MARC researchers, Mr. Nima Roohi Sefidmazgi, Mr. Pouya Temourpoour, and Dr. Hussain Bahia, entitled "Effect of Particle Mobility on Aggregate Structure Formation in Asphalt Mixtures" was awarded the Walter J. Emmons Award for the best paper presented at the Association of Asphalt Paving Technologists 2013 Annual Meeting held in Denver, Colorado. The award has been conferred annually to the best presented paper at the AAPT annual meeting since 1949. The award will be presented to the authors at the 2014 Annual Meeting, to be held in Atlanta, GA from March 16-19, 2014.

Solicitation for Transportation Pooled Fund Project on Modified Asphalt Specifications
WisDOT and the Modified Asphalt Research Center at University of Wisconsin - Madison, are partnering to from a pooled fund studying binder specification test methods. Participation in this pooled fund presents an opportunity for specifying agencies and users to support research on development of specifications and acceptance criteria for modified binders with a focus on test methods that are most related to performance and meet specific needs. The product of this research will be a unified modified binder specification developed in cooperation with partner states and User-Producer Groups delivered in a format that will allow for rapid implementation and deployment. For more information on the project and how to join, please visit the FHWA approved solicitation posted on the Transportation Pooled Fund website.

MARC Researchers Present at 50th Petersen Asphalt Research Conference
MARC Researchers, Dr. Hussain Bahia and Dr. Hassan Tabatabaee presented some of the latest findings and developments at the 50th Petersen Asphalt Research Conference, held at Laramie, WY, Jul 15-17, 2013. Dr. Hassan Tabatabaee presented an new asphalt binder healing index methodlogy based on application of diffusion mechanism to crack propogation in the Dynamic Shear Rheometer. The index was used to rank binders of various aged binder content, modification level, and loading temepratures in terms of rate of healing subsequent to fatigue damage. Dr. Hussain Bahia discussed new work by MARC looking into the observed effects of mineral fillers on the oxidative aging of asphalt binders, in terms of mechanical and thermo-volumeteric properties. Copies of the presentations are available to MARC partner upon request.
