A concrete walk with a thickened edge interfaces with a concrete curb featuring tooled one-half inch radius edges. A one-half inch expansion joint separates the walk and the curb, which extends down past an asphalt concrete layer and aggregate base to natural grade. The walk slab thickness is sized per plans, featuring a thickened edge that extends downward with an eight-inch horizontal seat. General notes specify providing expansion joints at sixteen feet on center maximum and at curve tangents and corners, with construction conforming to structural and civil recommendations.
