Abstract: The cause of the white-etching regions outlining certain subsurface cracks in rail-heads was investigated. These cracks known as shells may propagate into “shelly spots,” i.e., deep spalls, usually ...

Abstract: Analytical and numerical models of capillary barrier performance commonly use hydraulic characteristics measured using pure water. However, the potential exists for an infiltrating solution to have a surface tension lower ...

Abstract: It is generally agreed that the friction between a tire and a wet pavement (skid resistance) is controlled by the surface texture characteristics. Therefore, by measuring the relevant parameters ...

Abstract: Two independent state-of-the-art equations for incipient hydroplaning speeds, which were regressed from experimental data for different ranges of magnitudes of water film thicknesses, are investigated relative to merging ...

Abstract: Improved flow-visualization methods based on the hydrogen-bubble technique are described. Use of “combined-time-streak markers” allows quantitative measurement of the instantaneous velocity field in ...

Abstract: Experimental testing was conducted on four large-scale, flexure-yielding walls with rectangular cross sections to investigate the impact of imposed axial load ratio (1, 14, and 2% of axial compression capacity) and transverse ...
