PAVEMENT MANAGEMENT SYSTEM <br />A Pavement Management System (PMS) performs analysis of collected rating data and reports <br />on the current and projected conditions of the street system. In addition,it is used to evaluate the <br />effectiveness of planning and funding priorities, and provides guidance in the decision making <br />process.The goal of the decision making process is to prevent pavement failures through <br />judicious maintenance. <br />City of Eugene implemented MicroPaver in 2013. MicroPavercombines visual field inspection <br />ratings, compiled under strict criteria, with computer tracking and condition analysis. Beginning <br />collection of deterioration values by area, lineal footage thus keeping the program consistent <br />with industry standards. This also allowed for smoother transition to MicroPaver with the ability <br />to migrate three years of rating data with some modifications. With this migrated condition data, <br />rating the entire asphalt street system the last three years plus construction history we are able to <br />perform an analysis with rational accuracy to report financial needs and road conditions. There <br />will be some variation in the outcomes of the analysis due to slight differences in rating and <br />calculation methodology but overall the data is consistent. <br />Pavement Inspection Frequency <br />Two predominant work efforts required to maintain the PMS are updating the street inventory <br />and performing the annual inspection of surface conditions. <br />City streets are divided into segments based on their Functional Classification (FC), pavement <br />type, and geometricdesign. Segments are the basic unit for evaluating streets and surface <br />conditions. A segment is defined as a portion of a street with a beginning and ending description. <br />Changes in geometric features are used as a guide for determining segments. Examples of <br />geometric differences are surface type, segment width, surface age, and extent of past <br />rehabilitations. <br />Field inspections are conducted by pavement raters who walk each individual street segment <br />evaluating the pavement surface for signs of distress. City arterial and collector streets are <br />inspected annually; residential streets inspections are completed in a three-year cycle; and off- <br />street shared-use path inspections are completed in a two-year cycle. <br />Staff performed inspections on the entire street system using MicroPaver for the first three years, <br />2013-2015 providing an accurate baseline for analysis. Staff returnedto the annual inspection <br />cycle in 2016. This year, 2017, staff inspected 157 miles of arterial and collectorstreets,100 <br />miles of local streets in the University and Danebo/Bethel areas,plus 44 miles of off-street bike <br />paths. <br />6 <br /> <br />
