The <br /> key steps in joint layout include: <br /> • Calculating maximum slab sizes <br /> — max. slab length = 24 x T (thickness) on granular subbases; 21 x T on stabilized subbases <br /> — max. slab width = 14 feet (4.3 m); lane width is typically the slab width <br /> • Doglegging joints near the pavement edge <br /> — all joints should intersect the edge of pavement at a 90° angle <br /> — if needed, dogleg the joints within 2-3 feet (0.5-1.0 m) of the pavement edge <br /> • Adjusting joint locations to meet in-pavement structures such as drainage inlets and manholes <br /> — immovable structures in the pavement will cause cracks to form if joints are not provided <br /> • Avoiding "L-shaped" slabs (interior corners) <br /> A typical joint layout with integral colored crosswalks is shown in Figure 6 on the next page. <br />
