The edge condition features a thickened section bearing on compacted soil with a clear cover of 3 inches. Reinforcement consists of number 4 continuous horizontal bars and number 4 bars with standard hooks spaced at 18 inches on center extending into the slab. A 1-foot-6-inch dimension marks the extent of the reinforced slab transition zone adjacent to the exterior paving.
