PAVEMENT MANAGEMENT SYSTEM Effective evaluation of planning and funding priorities necessitate that local jurisdictions manage their transportation infrastructure with some form of pavement management system. Generally, the PMS provides guidance in the decision making process and is designed to prevent pavement failures through judicious maintenance. The Pavement Management System performs analysis and reports on the current and projected condition of the pavement surface. The system is dependent on the annual condition inspections/surveys that are conducted. The PMS used by the City of Eugene since 1987 was developed by Washington's League of Cities and Washington County Roads Administration Board (CRAB) in conjunction with the Washington Department of Transportation (WDOT). The PMS combines visual field inspection ratings, compiled under strict criteria, with an automated computer tracking and condition analysis program, called CenterLine. Together these components of PMS document current pavement condition and serviceability, and provide a basis for modeling project financial/condition trends. Eugene's PMS contains 20 years of historical data and has the ability to estimate financial needs and road conditions twenty years into the future. Pavement Inspection Frequency Two predominant work efforts required to maintain the PMS are updating the street inventory and performing the annual inspection of surface conditions. City streets are divided into segments based on their Functional Classification (FC), pavement type, and geometric design. Segments are the basic unit for evaluating streets and surface conditions. A segment is defined as a portion of a street with a beginning and ending description. Changes in geometric features are used as a guide for determining segments. Examples of geometric differences are surface type, segment widths, surface age, and extent of past rehabilitations. Annual field inspections are performed on all the City's arterials and collector streets. Since the rate of deterioration of a local street is typically less than that seen on higher classification streets, field inspections are performed on one-third of the local streets each year which places all local streets on a three-year inspection cycle. Field inspection is conducted by pairs of pavement raters who walk each individual street segment evaluating the pavement for signs of distress. Discrepancies between the ratings of the two pavement raters, or from the previous years’ ratings are reason for the segment to be rated a second time to ensure a correct evaluation. Overall Condition Index (OCI), Deduct Values, and Distresses Pavement raters walk streets evaluating the pavements for signs of distress. Distresses occurring in streets are dependent on pavement type and are rated by extent and severity. These values are logged on standard forms designed for the field surveys. Distresses occur in many phases of deterioration; therefore, the predominant extent and severity is rated. The data is then entered into CenterLine. Numerical values (deduct values) are assigned to each distress’ extent and severity, all deduct values are summed and then subtracted from the base value of 100 internally. The final value, designated as the overall condition index (OCI), 6
