pavement distress manuals, one for use with concrete and the other for use with asphalt pavement. Small and spiral bound, the manuals are designed for easy use in the field. They identify low-, medium-, and high-severity levels of each pavement distress with photos. Distresses are categorized by their cause: environmental, traffic, or construction.

1.3 Manual Format The manual is comprised of the following chapters: • Chapter 2 - Pavement Condition Surveys • Chapter 3 - Surface Distress Guidelines – Network Surveys • Chapter 4 - Surface Distress Guidelines – Manual Surveys • Chapter 5 - Asphalt Surface Distress Rating System

Asphalt pavement distress PASER uses visual inspection to evaluate pavement surface conditions. The key to a useful evaluation is identifying different types of pavement distress and linking them to a cause. Understanding the cause for current conditions is extremely important in selecting an appropriate maintenance or rehabilitation technique.

This manual is prepared to assist users of the Bay Area Pavement Management System (PMS) in identifying surface distress in a uniform and repeatable manner. The distresses in- cluded in this manual are used to calculate the Pavement Condition Index (PCI) for pavements surfaced with asphalt concrete and surface treatments.

Fig. 7. Pavement with no cracking. Fig. 4. High severity longitudinal cracking. Asphalt concrete surfaced pavement with moderate severity reflection cracking is shown in Fig. 5. This crack has a mean width of 11 mm. From the distress area, it can be viewed that cracks in the asphalt concrete are in the overlay surface, which was at joints.

of distress and levels of severity. The definitions used in the PAVER system are some of the most commonly used by local agencies (6,7); however, they are often criticized because there are too many distress types required by PAVER (19 each for asphalt and concrete surfaced pavements, 7 for unsurfaced roads). Since PAVER was developed
