Abstract: A set of cast concrete paving slabs is laid in a pattern side by side and end to end to cover an area to be paved. Each of the slabs members has side and end spacer abutments to hold an adjacent slab member at a predetermined spacing. Each of the slabs has a longitudinal slot in the upper surface defining a false joint parallel to the sides so as to divide the upper surface into parallel strips. There are different types of slabs some with both strips divided by transverse slots and some with only one strip with a slot. This forms in the finished product apparent strip pieces of many different lengths to simulate wood planks. Each of the parallel strips has a molded upper surface defining a series of wavy lines recessed from other parts of the upper surface and dyed darker than the remaining part of the slab thus simulating a wood grain appearance.
