The joint widths, i.e., the separation space between two pavers, were measured in all cells. Ninety measurements were taken using digital callipers (0.2 mm accuracy), surrounding fifteen random pavers over the area of each PICP cell, seen in Figure 2-4. No joint width measurements were taken close to the edge of the cells because maintenance vehicles did not reach that portion. Table 2-1 below summarizes the descriptive statistics generated for the joint spacings.
