Book excerpt: Nearly all State highway agencies use smoothness specifications to ensure that hot-mix asphalt (HMA) and portland cement concrete (PCC) pavements are built to high levels of smoothness. About half of all current State smoothness specifications for HMA and more then three-fourths of all current PCC smoothness specifications are centered around the Profile Index (PI), as often measured using a profilograph. The vast majority of these specifications utilize a 5-mm (0.2-in.) blanking band in computing PI (i.e., PI5-mm). Assistance in selecting appropriate IRI and PI0.0 specification limits is needed to provide a basis for modifying current specifications to these more reproducible and portable smoothness indices. This research effort has developed a series of relationships between IRI and PI that can assist States in transitioning to IRI or PI0.0 smoothness specification for HMA and PCC pavements.

Download or read book Measurements Specifications and Achievement of Smoothness for Pavement Construction written by James H. Woodstrom and published by Transportation Research Board. This book was released on 1990 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: This synthesis will be of interest to construction engineers, pavement designers, contractors, and others interested in construction of new highway pavements with smooth surfaces. Information is provided on the various devices and specifications that are being used to obtain smooth pavements. The public rates a pavement primarily on its smooth-riding characteristics and highway agencies recognize that constructing smooth pavements results in fewer problems later and lower annual maintenance costs. This report of the Transportation Research Board describes the devices and specifications highway agencies use to ensure that newly constructed pavements will provide a smooth ride.

Available in PDF, EPUB and Kindle. Book excerpt: In its pursuit for providing smooth pavements, the Directorate General of Highways in Taiwan is developing and implementing ride quality specification as part of the construction assurance program. The straightedge and the profiler were used to measure pavement smoothness on 561 test sections. Probability distribution analysis showed that measurements of pavement smoothness of both devices follow the normal distribution. Smoothness specifications for construction quality control were developed for straightedge and profiler, respectively. The full-pay range is 1.36 to 2.45 mm and 2.16 to 3.65 m/km for straightedge and profiler, respectively. The smoothness relationship between straightedge and profiler was developed.

Download or read book Implementation of an International Roughness Index for Mn DOT Pavement Construction and Rehabilitation written by W. James Wilde and published by . This book was released on 2007 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report documents the development and preparation for implementation of a specification for using International Roughness Index, using an inertial profiler, as a smoothness measure for new portland cement concrete pavements in Minnesota. This new specification represents a departure from the use of the Profile Index, using a California Profilometer, for concrete pavement smoothness. In addition to providing recommendations to the Minnesota Department of Transportation regarding the implementation of the specification, the report contains additional information and analyses. These include a summary of the specifications in use by other states for measurement and incentive/disincentive payment for concrete pavement smoothness, an analysis of the effects of pavement surface characteristics on the International Roughness Index and the Profile Index, and a comparison of IRI-based concrete pavement smoothness specifications in use by other states. The report concludes with several recommendations for the new specification and for its administration and enforcement by the Minnesota Department of Transportation.

Book excerpt: Smooth pavement can reduce vehicle operating costs and is valued highly by both travelers and shippers. Because all states must report International Roughness Index data for their National Highway System roads, pavement smoothness is also an important performance measure for the State DOTs. This report identifies states that have achieved exemplary performance in achieving smooth pavements and documents their best practices. The second in a series of reports for the Subcommittee on Performance Measurement and Benchmarking of the Standing Committee on Quality, this report on measuring pavement smoothness is co-sponsored by the Subcommittee on Transportation Asset Management of the Standing Committee on Planning.

Download or read book Smoothness Index Relationships for HMA Pavements written by L. Titus-Glover and published by . This book was released on 2003 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: A recent Federal Highway Administration survey indicated that 48 states and Puerto Rico use smoothness specifications for hot-mix asphalt (HMA) pavement construction. As this is a relatively new concept, many states have adapted the Portland cement concrete pavement specifications of Profile Index using the standard 5-mm blanking band (PI5.0) for use on HMA pavements. However, PI5.0 may not provide a reproducible or portable smoothness measure for HMA pavements because of the technical limitations of the equipment and procedures.
