Embedment length depends on bar size and is needed to develop the tensile load of the reinforcing bar. If embedment length is insufficient, the reinforcing bar will pull out of the concrete before it can transfer the entire load the steel can handle. Table 5.1 shows the embedment length required for different size bars and 2-inch concrete cover. tance first created by wild animals were later used by settlers. As needs and traffic increased, these traveled ways became roads which were gradually improved with gravel or crushed rock. Little engineering went into these improvements. Using available materials and keeping them out of the mud were the extent of efforts to maintain a road.
