About this detail

This concrete paving detail shows a reinforced concrete slab bearing on a three-inch aggregate base and a ninety-five percent compacted subgrade with a twenty-four-inch minimum depth. The slab features a thickened edge measuring eight inches in pedestrian areas and twelve inches in vehicular areas, with a half-inch radius edge at turf conditions. Reinforcement consists of continuous number four rebar alongside number four rebar at twelve inches on center each way in vehicular areas or ten gauge twelve-inch by twelve-inch welded wire mesh in pedestrian areas. A control joint is set one-eighth inch wide by one and a half inches deep, and a full-depth half-inch thick Foamtech expansion joint with a half-inch deep bead of elastomeric sealer dusted with fine grain sand occurs adjacent to buildings and walls.
