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.

Of those claims, the Tort Claimants’ Committee estimates that there are approximately 83,807 unique claims if the amended and superseded and multiple claims filed on account of the same survivor are removed. The summary of sexual abuse claims below uses the set of 83,807 of claim for purposes of claims summary below.1 The Tort Claimants’ Committee has broken down the sexual abuse claims in various categories for the purpose of disclosing where and when the sexual abuse claims arose and the identity of certain of the parties that are implicated in the alleged sexual abuse. Attached hereto as Exhibit 1 is a chart that shows the sexual abuse claims broken down by the year in which they first arose. Please note that there approximately 10,500 claims did not provide a date for when the sexual abuse occurred. As a result, those claims have not been assigned a year in which the abuse first arose. Attached hereto as Exhibit 2 is a chart that shows the claims broken down by the state or jurisdiction in which they arose. Please note there are approximately 7,186 claims that did not provide a location of abuse. Those claims are reflected by YY or ZZ in the codes used to identify the applicable state or jurisdiction. Those claims have not been assigned a state or other jurisdiction. Attached hereto as Exhibit 3 is a chart that shows the claims broken down by the Local Council implicated in the sexual abuse.

  • Science Concept 3: Key Planetary
    Science Concept 6: The Moon is an Accessible Laboratory for Studying the Impact Process on Planetary Scales Science Concept 6: The Moon is an accessible laboratory for studying the impact process on planetary scales Science Goals: a. Characterize the existence and extent of melt sheet differentiation. b. Determine the structure of multi-ring impact basins. c. Quantify the effects of planetary characteristics (composition, density, impact velocities) on crater formation and morphology. d. Measure the extent of lateral and vertical mixing of local and ejecta material. INTRODUCTION Impact cratering is a fundamental geological process which is ubiquitous throughout the Solar System. Impacts have been linked with the formation of bodies (e.g. the Moon; Hartmann and Davis, 1975), terrestrial mass extinctions (e.g. the Cretaceous-Tertiary boundary extinction; Alvarez et al., 1980), and even proposed as a transfer mechanism for life between planetary bodies (Chyba et al., 1994). However, the importance of impacts and impact cratering has only been realized within the last 50 or so years. Here we briefly introduce the topic of impact cratering. The main crater types and their features are outlined as well as their formation mechanisms. Scaling laws, which attempt to link impacts at a variety of scales, are also introduced. Finally, we note the lack of extraterrestrial crater samples and how Science Concept 6 addresses this. Crater Types There are three distinct crater types: simple craters, complex craters, and multi-ring basins (Fig. 6.1). The type of crater produced in an impact is dependent upon the size, density, and speed of the impactor, as well as the strength and gravitational field of the target.
