Guidelines for Construction of Concrete Footpath Slabs

understood and documented. Concrete slabs used in residential footpaths transfer weight of pedestrian traffic and bicycle traffic to the ground. Slabs are relatively narrow (approximately 1.5 m) and the length of each panel is determined by the spacing of control joints. If the supporting sub-base is firm, the footpath slab is capable of resisting
