Available in PDF, EPUB and Kindle. Book excerpt: This study was initiated by ODOT to evaluate the performance of four pavement marking materials (fast dry traffic paint, polyester, extruded thermoplastic and epoxy) in order to determine which materials are most suitable for the environmental and traffic conditions in ODOT District 11, which contains mostly rural roads with relatively low traffic levels (ADT less than 5,000 vehicles per day) and some areas of mountainous terrain. The main focus of this study was to evaluate the performance of fast dry traffic paint and polyester as restriping materials; however, epoxy and thermoplastic were included in the evaluation for comparison purposes. The four materials were installed at 11 test sites distributed across the district on two-lane and four-lane highways having a variety of pavement types, pavement geometries, and traffic volumes. The performance of the pavement markings was evaluated in the field for a period of two years in terms of dry retroreflectivity, daytime color, and durability. Laboratory test procedures were also included to examine the quality of the glass beads used in this study. The field performance results were analyzed to determine the service life of the various marking materials. In addition, the results were used to estimate the life cycle cost of these materials and develop a material selection matrix for use in District 11. Based on the outcome of this study, it was recommended that District 11 continue to use epoxy on new asphalt and concrete surfaces and to use traffic paint for restriping applications. For two-lane roads with asphalt surfaces, it was recommended to restripe the edge lines every two years and restripe the centerlines every year. On selected roads with sharp curves that slope towards the Ohio River, it was recommended to restripe the centerlines as well as the edge lines on an annual basis to avoid run-off road crashes. For multi-lane roads with asphalt surfaces, it was recommended to restripe locations with low traffic and good pavement condition every two years and restripe all lines at locations with high traffic (ADT greater than or equal to 10,000 vehicles per day) or rough pavement condition (pavement condition rating (PCR) less than 80) every year. For all roads with concrete surfaces, it was recommended to restripe all lines every year regardless of the traffic level and pavement condition. One material that is increasingly being used in Ohio for striping and restriping applications on asphalt surfaces is spray thermoplastic. This material was not included in this study because it is not compatible with epoxy, which was previously installed on several of the test sites prior to the beginning of this project. Some districts reported favorable results from using spray thermoplastic. Therefore, District 11 is encouraged to look into using this less expensive material as an alternative for epoxy markings on new asphalt surfaces. It should be emphasized that the previous recommendations are specific to District 11 and may not be applicable to other ODOT districts due to variations in traffic levels, environmental conditions, and pavement marking material selection practices.
Download or read book Pavement Forecasting Models written by Eddie Chou and published by . This book was released on 2008 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: The primary objectives of this study were to develop models to forecast future pavement conditions and to determine remaining service life of pavements based on the forecasted conditions. Based on available data in the ODOT pavement database, which contains the condition history of each pavement section, along with its location, year of construction, thickness, materials used, climate, and rehabilitation records, individual regression, family regression, and Markov probabilistic models were developed . For the latter two models, pavements were first grouped into "families" with similar characteristics, based on pavement type, priority, District location, and past performance. Forecasting models were then developed for each such "family." The developed models were evaluated by comparing the predicted conditions with the actual observed conditions for the five year period between 2001 and 2005. The Markov model was found to have the highest overall prediction accuracy among all the models evaluated, and it can also predict future distresses in addition to the PCR values. As a result of this study, ODOT can forecast future pavement conditions and estimate the remaining service life of pavements. Future rehabilitation needs can also be determined. Such capabilities will significantly benefit planning and management decision-makings at both project and network levels

This book was released on 2007 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1994, a ramp containing two AC and two PCC sections in the SPS-8 experiment was constructed on the Ohio SHRP Test Road. In 1996, 36 more sections in the SPS-1, SPS-2 and SPS-9 experiments were opened to traffic on the mainline pavement. The response and performance of these sections, climatic information from an on-site weather station, subsurface environmental conditions from sensors installed in several test sections, and traffic loading from an on-site weigh-in-motion (WIM) system have been monitored and incorporated into the national LTPP database. Analyses of these data have been published in a number of reports, technical papers and bulletins. The research project documented in this report was the latest effort by ODOT to continue monitoring the response and performance of many of the original 40 test sections and several sections constructed later to replace the lighter designs which, as anticipated, showed early distress. Data in this report cover the years 2000-2005. In addition to the new response and performance data obtained on the test road, this report includes: an analysis of current methodologies to mathematically model AC and PCC pavement structures, a petrographic analysis of concrete from three different PCC pavement mixes and a lean concrete base, and an in-depth analysis of WIM data. Three other experimental pavements have been constructed on ATH 50, LOG 33 and ERI/LOR 2 to evaluate the response and performance of specific parameters of interest to ODOT. These parameters included: high performance concrete containing ground granulated blast furnace slag and different types of dowel bars on ATH 50, different types of base material under flexible pavement on LOG 33, and different types of base material under rigid pavement on ERI/LOR 2. This report also contains data collected on these three pavements during 2000-2005.

Book excerpt: The purpose of this manual is to provide clear and helpful information for maintaining gravel roads. Very little technical help is available to small agencies that are responsible for managing these roads. Gravel road maintenance has traditionally been "more of an art than a science" and very few formal standards exist. This manual contains guidelines to help answer the questions that arise concerning gravel road maintenance such as: What is enough surface crown? What is too much? What causes corrugation? The information is as nontechnical as possible without sacrificing clear guidelines and instructions on how to do the job right.
