    Disc shaped compact tension (DCT) specifications development for asphalt pavement
    (Minnesota Department of Transportation., 2019-06) Dave, Eshan V; Oshone, Mirkat; Schokker, Andrea; Bennett, Chelsea E
    The disc-shaped compact tension (DCT) fracture energy test has been shown to discriminate between asphalt mixtures with respect to their thermal cracking potential. This research refines the DCT fracture energy testing procedure, identifies needed adjustments in asphalt mixture to increase fracture energy, determines the suitability of DCT-test-based parameters as indicators of reflective cracking, and proposes threshold values to lower the potential for premature reflective cracking in asphalt overlays. A number of recommendations have been developed to implement outcomes of this research as well as to fill knowledge gaps identified through this study.

    University of Minnesota Traffic Simulation Study, Washington Avenue Corridor
    (University of Minnesota and BRW Inc., 1997-07-17) BRW Inc.
    This report documents the results of the analysis conducted to address several issues resulting from March 12, 1997 and April 8, 1997 meetings regarding the Washington Avenue Corridor traffic simulation study. Identified issues for further analysis in order to complete the corridor study included the impact of a pedestrian scramble on traffic, the impact of adding a northbound right-turn lane, documenting accident history on Washington Avenue, reviewing shoulder guidelines, and increasing signal timing splits. This report presents the overall recommendations based on the results of the study.
