Download or read book Review of ODOT's Overlay Design Procedures: HMA overlays of existing HMA and composite pavements written by and published by . This book was released on 2008 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: ODOT initiated this research study to determine (1) the impact of milling off portions of the existing pavement on the structural capacity of the remaining pavement and (2) whether currently recommended HMA structural coefficients adequately reflect the structural properties of new HMA overlay materials. The study mainly focused on the impact of milling on the design of HMA overlays over existing flexible pavements and composite pavements. Volume I of the report deals with this main study focus area. During the course of the study, an additional focus area was added to the project to investigate the impact of completely milling off existing HMA layers in composite pavement systems on unbonded overlay design. Volume II of this report deals with impact of milling on unbonded overlays. Volume I describes the structural evaluation of individual flexible and composite pavement projects located at different sites throughout Ohio, as well as an analysis of the evaluation results to develop enhancements to the ODOT HMA overlay design procedure as needed. The report presents detailed descriptions of the projects evaluated, field testing procedures employed, procedures adopted for analyzing field testing data and other data collected, structural evaluation results, analysis of results, and recommendations for improvements of the current ODOT overlay design procedure. Volume II presents descriptions of the data collected, data analysis, observations, and recommendations for improvements of the current ODOT overlay design procedure.

Book excerpt: As the US Highway system ages and available funding diminishes, transportation agencies are looking for effective methods for preserving and extending the life of existing pavements. These agencies are also being encouraged to minimize construction times and reduce the impact to the traveling public. Currently, the most common method of rehabilitating an existing roadway surface is through an HMA overlay; however, high oil prices have caused designers and agencies to consider other methods. One alternative to the traditional HMA overlay is a concrete overlay. The Iowa Department of Transportation (Iowa DOT) and Iowa counties and cities have completed about 1,000 miles of concrete overlays that are in use and are serving the traveling public today. Despite the completion of hundreds of projects, some agencies are reluctant to use concrete overlays, believing that they are expensive, difficult to build, and have limited application. To address these concerns, the National Concrete Pavement Technology Center at Iowa State University developed a guide document to assist engineers in concrete overlay design and construction. The Guide to Concrete Overlays was published in September 2008 and includes detailed information on evaluating existing pavements as concrete overlay candidates, selecting and designing the appropriate type of concrete overlay, and guidance on concrete overlay construction. Since the publication of this guide, the need has arisen to develop methods to improve concrete overlay efficiency utilizing current technology, investigate innovative materials for use as bond breakers, and reduce the inconvenience to the public with improved methods of traffic control and increased opening time.

Book Synopsis Design and Construction Recommendations for Thin Overlays in Texas by : Bryan T. Wilson

Available in PDF, EPUB and Kindle. Book excerpt: Thin hot mix asphalt (HMA) overlays, laid at 1.0 inch or thinner, are cost-effective surface maintenance options. The primary focus of this research was to develop specifications for three such mixes: fine dense-graded mix (fine DGM), fine-graded stone matrix asphalt (fine SMA), and fine-graded permeable friction course (fine PFC). A number of slurry overlay systems were also evaluated, but to a lesser extent. Draft specifications for the three mix types were first developed based on the results of a literature/information search and a field investigation of 11 existing projects. The specifications included minimum material quality levels, laboratory performance criteria, and construction recommendations. To evaluate the design recommendations, extensive laboratory testing was performed on each of the three thin overlay mixes with five different aggregates. Of the 15 mixes attempted, 12 had acceptable designs in terms of the specified performance tests. For the most part, the draft specifications appeared to function well with minor alterations recommended. Testing also included two supplementary studies on the effects of screening type in fine SMA and the effects of recycled materials on both the fine SMA and fine PFC. Compaction of the fine SMAs was highly influenced by packing characteristics of the coarse and fine aggregates. Screening quality did not affect fine SMA rutting resistance, but did affect cracking resistance. Using recycled aggregates reduced rutting problems but increased cracking susceptibility; however, most mixes performed well suggesting that quality, well-engineered mixes can still have good performance when recycled materials are used in limited amounts. Concerning laboratory testing of slurry overlays, the applicability of the overlay tester/procedures and the three-wheel polishing device in testing should be further studied. In particular, a tie-in with actual field performance should be identified, perhaps with the Accelerated Pavement Test program. Six thin overlay projects, comprising 10 unique mix designs, were constructed and evaluated. Most projects were constructed without problems, though some encountered issues with over- and under-compaction. Initial performance has been very good, although, since all the sections are less than two years old, the long-term performance is still undetermined. The researchers recommend adapting the specifications accompanying this report, which require using high quality materials and passing strict laboratory performance tests on both the lab design and trial batch materials. They do not recommend incorporating recycled materials in these mixes, though preliminary results are promising. Guidelines for pavement evaluation and mix selection were also prepared, which recommend the use of certain thin overlay or slurry overlay options given the pavement, traffic, and climate conditions.
