About this detail

Various pedestrian concrete paving conditions include thickened slab edges at planting areas, sawcut control joints, doweled expansion joints, and vertical surface interfaces. The concrete slab rests on a Class II aggregate base with a thickness determined by the geotechnical report, reinforced with number 3 rebars at 18 inches on center each way with a 3-inch clear cover. Sawcut joints are installed at one-quarter of the slab depth. Expansion joints feature a quarter-inch foam filler such as Ceramar, a snap cap, and a self-leveling joint sealant with a sand covering, alongside number 3 by 18-inch long smooth dowels centered on the joint at 18 inches on center with a speed dowel provided on one side. Reinforcing parallel to the joint stops 3 inches clear on each side, while perpendicular reinforcing continues through. Cold construction joints incorporate similar smooth dowels, and non-doweled expansion joints occur at vertical concrete surfaces per plan.
