A cast-in-place concrete curb interfaces with a concrete walk featuring a thickened edge. A one-half-inch expansion joint separates the walk from the curb, which features tooled one-half-inch radius edges. The walk slab rests on prepared subgrade and incorporates a thickened edge extending eight inches wide. The adjacent curb section sits on aggregate base and asphalt concrete layers, with an eighteen-inch minimum depth to natural grade. General notes specify providing expansion joints at sixteen feet on center maximum and at curve tangents.
