The findings from this study were based on limited data. Requests for candidate structures for the inspections indicated that relatively few suitable bridges were available. Only 6 of those bridges could be skid tested. A further limitation was that, since the texturing specification was relatively new, the effect of traffic wear over a substantial period of time could not be measured. Skid resistance data from tests with treaded tires at 40 mph in the traffic lanes of interstate highway bridges, obtained routinely as part of another program, were available to indicate the effect of wear on earlier bridge deck textures.
Hydraulic cement concrete overlays are usually placed on bridges to reduce the infiltration of water and chloride ions and to improve skid resistance,...
