A concrete walk with a thickened edge abuts a concrete curb with a half-inch expansion joint placed between them. The top edges of both the curb and walk feature tooled half-inch radius edges. The curb has a six-inch top width with dimensions varying or per civil plans, bearing on a minimum eighteen-inch total depth comprising aggregate base and asphaltic concrete layers over natural grade. The walk features an eight-inch wide thickened edge bearing on compacted subbase. General notes require half-inch expansion joints at sixteen feet on center maximum, curve tangents, and corners, with slab construction per structural and soils reports.
