MARC Project Receives CTS Research Partnership Award
MARC research project, "Investigation of Low Temperature Cracking in Asphalt Pavements National Pooled Fund Study - Phase II," received the 2013 CTS Research Partnership Award. The award, which is awarded by the University of Minnesota Center for Transportation Studies, recognizes research projects within the CTS program that have resulted in significant impacts on transportation, and rewards teams of individuals who have drawn on the strengths of their diverse partnerships to achieve those results. The awarded roject was conducted through a partnership led by the University of Minnesota and including MARC, University of Illinois, and Iowa State University.

MnDOT Publishes Final Report for the National Pooled Fund Study on Low Temperature Cracking - Phase II
Lead by the University of Minnesota in partnership with UW-MARC, University of Illinois, and Iowa State University, the Pooled Fund Study on Low Temperature Cracking of Asphalt Pavements - Phase II has been completed. This study proposes two fracture testing methods and specifications for selection of mixtures that are resistant to thermal cracking. UW-MARC contributions to this study include highlighting the importance of physical hardening and thermo-volumetric properties for accurate prediction of thermal stresses.

MARC to hold 3rd Workshop on Mixing and Compaction of Hot and Warm Asphalt Mixtures in August 2013
The Modified Asphalt Research Center (MARC) will host its third workshop on the factors affecting mixing and compaction temperatures of conventional and non-conventional HMA products on August 14-15, 2013. The main objective of this workshop was to introduce new technologies to evaluate mix components properties that affect compaction and to provide an open forum for discussion on how these technologies can be applied to improve current mix design procedures. The first and second offerings of this workshop were held in December 2012, and March 2013, respectively. For more information and registration please visit the workshop webpage.
