Pavement Management Engineer SUBJECT: 2020 Pavement Condition Report Attached is a copy of the Oregon Department of Transportation 2020 Pavement Condition Report produced by the Pavement Management team as a product of data collection efforts for the Pavement Management System. This report presents the results of the pavement condition survey work conducted during the summer of 2020. Pavement conditions are determined for all state mainline highways under the jurisdiction of the Oregon Department of Transportation. Pavement condition surveys are conducted on a biennial basis. The next Pavement Condition Report is scheduled for 2022.

Computation of Indices 2020 PAVEMENT CONDITION REPORT JANUARY 2021 EXECUTIVE SUMMARY Pavement is one of the largest assets that the Oregon Department of Transportation (ODOT) manages. ODOT maintains roughly 7,350 centerline of state highways with over 18,000 lane miles of pavement and strives to be a good steward of the state’s transportation assets through efficient use of taxpayer resources. Fortunately, ODOT’s asset management and investment strategies have recognized the importance of pavement maintenance and repair and pavement conditions have been relatively stable, exceeding the State Key Performance Measure (KPM) of 85% fair-or-better (%FOB) for the last several years. The 2020 state highway pavement measure is 89% fair-or-better, down one percent from 2018. Pavement conditions are being sustained in the near term due to additional pavement projects programed from higher than anticipated Fixing America’s Surface Transportation (FAST) Act funding and from early delivery of Keep Oregon Moving (HB 2017) funded pavement projects. Over the long term, even with HB 2017 funding, the pavement program is underfunded, which will lead to a decline in conditions. Pavements are load-carrying structures that degrade over time due to the cumulative effects of traffic, weather, and material aging. To keep them properly maintained and out of poor condition, they must be resurfaced or rehabilitated at periodic intervals. Typical ranges of service life and cycle times are: • Asphalt – 15 to 20 years (typical average – extremes vary from 10 or less to 30 or more) • Concrete – 40 to 60 years As long as degradation is confined to the surfacing only, and the pavement’s foundation and base layers are protected, a given pavement can be resurfaced over and over again, with occasional strengthening, but without the need for a complete replacement. However, if resurfacing is delayed for too long, the pavement structure and underlying base materials can become excessively damaged and complete replacement (e.g. reconstruction) becomes necessary at a much higher cost. The typical cost to restore a severely damaged road is orders of magnitude higher than the cost to preserve pavement through seals and resurfacing treatments. Timely maintenance and preservation are by far the most efficient way to preserve our investment. ODOT Pavement Services Unit i 2020 PAVEMENT CONDITION REPORT JANUARY 2021 An estimated $220 million a year is required in funding to repair the backlog of high cost poor and very poor highways, while keeping the remaining state highways in fair-or-better condition. This funding level would support major repairs needed on routes with the worst pavement conditions, while providing for timely preventive preservation and maintenance on roads in fair to good condition. Pavement funding levels over the last few years have averaged over $140 million per year, but the 21-24 STIP funding is at $107 million per year and will likely be even less in the 24-27 STIP. Preservation project mileage programmed in the 21-24 provides an equivalent resurfacing cycle time of 50 years, which is roughly twice as long as pavement lasts. Without additional Pavement funding, there will be a substantial drop in miles treated, leading to a corresponding decline in pavement conditions. This will result in diminished safety and higher vehicle repair costs for Oregonians traveling on rutted and potholed roads. In the long run, Oregonians will pay more to rehabilitate failing pavement than it would have cost to maintain them in a state of good repair. ii ODOT Pavement Services Unit 2020 PAVEMENT CONDITION REPORT JANUARY 2021 OREGON DEPARTMENT OF TRANSPORTATION 2020 PAVEMENT CONDITION REPORT INTRODUCTION The Oregon Department of Transportation (ODOT) 2020 Pavement Condition Report presents the results of pavement condition surveys conducted on the state highway system in the summer/fall of 2020. These surveys are conducted on mainline state highways under ODOT's jurisdiction, excluding frontage roads, connector ramps, and gravel surfaced roads. This report summarizes pavement condition results in various ways and provides a listing of pavement condition ratings for all state highways by pavement management section. The appendices of this report also include a listing of pavement repair projects and additional information regarding the computation of pavement conditions from the data. The information obtained from the pavement condition surveys provides ODOT with a measure of the current health of the state highway system. The pavement condition data also enables ODOT to track pavement performance and determine rehabilitation and funding needs on a network wide basis. These activities fall under the responsibility of the Pavement Services Unit as part of the Department's Pavement Management System. Pavement condition surveys are currently conducted on a biennial basis during even-numbered years.
