the OCI decrease reflects surface deterioration. This OCI value is the basis used to analyze the <br />surface treatment needs of the individual segments. <br />Asphalt distresses typically. observed-are alligatoring, longitudinal and transverse cracks, <br />rutting, raveling,. and some maintenance procedures such as crack sealing and patching. <br />Concrete distresses observed are cracks per panel, raveling, joint spalling, faulting, and crack <br />sealing. <br />How PMS Information is Used <br />The primary purpose of maintaining a PMS is to collect and analyze inlu~nation relating to <br />street system condition and trends which provide Public. Work ~ agers vital information <br />which helps to ensure that the most cost effective mainten or ilitation strategies are <br />performed at the optimum time. <br />Each year the PMS is used to generate several reports , to by othe cies as well as <br />statistical data requested within our own agency.

In this section, current cost analyses are shown and <br />the roles o lie Works Engineering and Maintenance Divisions are discussed. Proposed <br />projects for P Pare shown 1'or 2007. <br />Treatment Types a nd Crists <br />Unit Costs were last reviewed and updated in 2000 by Pavement Services, INC. Since then, <br />various sources have reported substantial increases in construction costs. One reason for the <br />increase was the cost ~of oil-based products. Staff reviewed cost trends provided by ODOT <br />and noted that costs for liquid asphalt has risen over 77%, from $207/ton to $368/ton, in a <br />nine month period. Public Works Engineering Division compared cost trend data, with the <br />current projects completed under the PPP program and recalculated unit costs to reflect recent <br />price increases. After discussion with Pavement Services, INC., the 2% inflation factor <br />appeared to be appropriate to continue to use once the unit costs were updated. <br />Based on historic and current construction costs as tracked by the Engineering Division, each <br /> <br />
