    2020-05-01 | PDF
    Pedestrian-Activated Crossing (PAC) systems have been shown to have a generally positive impact on driver yield rates. However, there has been insufficient research on the effect PAC treatments have on pedestrian crash rates, and there is little guidance as to when and where each treatment should be used. This study estimates the effects of PACs on ...

    Load Rating Strategies for Bridges With Limited or Missing As-Built Information
    Harris, Devin K. ;
    Ozbulut, Osman E.
    2020-05-01 | PDF
    Load rating is the process of determining the safe load-carrying capacity of a bridge; however, when plans and details are insufficient to determine the overall capacity of the structure, alternative methods must be used to infer what the live load capacity is. Two viable methods allowed by the AASHTO Manual for Bridge Evaluation are the commonly u ...

    Field, Carrie ;
    Roberts-Wollmann, Carin L.
    2020-05-01 | PDF
    Adjacent box beam bridges are economical bridge systems for accelerated bridge construction. The box beams are constructed at precast plants and are traditionally connected by a shear key filled with grout. This system is typically used for short spans with low clearance restrictions. However, due to the grout deteriorating and debonding from the p ...
