This research proposes a framework for assessing the impacts of new and existing cycling infrastructure using minimum impedance routing. Impedance represents the relative difficulty of cycling taking into consideration travel time, exposure to automobiles, hills, and the provision of cycling infrastructure. An all-paths network is created from Open

This report discusses Oklahoma's second experimental internally sealed concrete bridge deck. It differed from the first on in that it contained wax beads only in the top two inches as opposed to full depth and it covered the entire deck instead of just one span. The objective of this study was to gain experience in placing and heating a wax impregn
