MARC Researchers Present Research Findings at 2015 AAPT Meeting in Portland, OR.
MARC researcher Mr. Amir Arshadi attended the 2015 Annual Meeting of the Association of Asphalt Paving Technologists (AAPT) which was held in Portland Marriott Downtown Waterfront Hotel, Portland, Oregon, on March 8-11, 2015. With his paper titled "Development of an Image-based Multi-Scale Finite Element Approach with Effective Simulation of Particle-to-Particle Contact Behavior to Predict Mechanical Response of Asphalt Mixtures" being accepted, Mr. Arshadi attended a technical session where his paper was listed in the program as "By Title" and had discussions with other researchers who were interested in this field. Ms. Raquel Moraes, the MARC alumni, also attended this meeting and presented her research findings on the effect of mineral filler on changes in molecular size distribution of asphalts during oxidative aging.

MARC Researchers Present at ARC Deliverables/Products Presentation and Workshop in Washington, D.C.
MARC researchers, Dr. Hussain Bahia and Mr. Pouya Teymourpour, presented some of the latest findings and developments in high, intermediate and low temperature properties of asphalt materials on Jan 15 in Washington, D.C., which was held as the Asphalt Research Consortium supported by Federal Highway Administration nears its completion. Dr. Hussain Bahia presented the low temperature cracking characterization of asphalt binders using Single Edge Notch Bending (SENB) test and the asphalt binder yield energy (BYET) and elastic recovery (ER) test using the Dynamic Shear Rheometer at intermediate temperature. Mr. Pouya Teymourpour demonstrated a newly developed method to characterize damage resistance to rutting of asphalt mixtures using iPas2 software. The presentations can be accessed here.

MARC Held Pooled Fund and WHRP Projects Kick-off Meetings
MARC held the kick-off meetings for the Transportation Pooled Fund project on "Modified Binder PG+ Specifications" and the Wisconsin Highway Research Program (WHRP) project titled "Analysis and Feasibility of Asphalt Pavement Performance-Based Specifications for WisDOT" on Oct 13, 2014. The intent of the pooled fund project is to provide essential information to state and local agencies to support standardization of PG+ specifications by identifying PG+ test methods that are reproducible and show promise in simulating actual field performance. For the WHRP project, it is aimed to develop a performance-based acceptance framework that applies to both mixture design and quality control/acceptance during production and further to assess the feasibility of implementing this framework into current WisDOT practice. MARC director Professor Hussain Bahia introduced the two projects in the meeting and discussed the staffing of the projects associated with the researchers and staffs of MARC. The two projects are about to start soon.
