1.2. Results PCI values provide an indication of the surface conditions and structural integrity of a pavement. The 0 to 100 PCI range is commonly divided into various categories using descriptive terms. Divisions between the terms are not fixed but are meant to reflect common perceptions of pavement conditions. Table 1 shows the categories chosen to represent the City's PCI assessment criteria, and it includes typical pavement distresses and M&R needs within each category. Table 1.
