Available in PDF, EPUB and Kindle. Book excerpt: High-speed non-contact laser profilers have become the standard testing equipment for pavement management ride quality testing. The same technology used in the high-speed profilers is now being used in lightweight profilers for construction smoothness testing. The lightweight profilers have many advantages over the California 25-ft profilograph. Despite the many advantages of the lightweight profilers, there is resistance from the contracting industry toward eliminating the 25-ft profilograph for construction ride testing. One way to reduce or overcome the resistance is to evaluate and demonstrate the advantages/disadvantages of the lightweight profiler in actual field use in Iowa. The objective of the study was to purchase a lightweight profiler and to evaluate its suitability for construction smoothness quality verification and quality acceptance on Iowa projects. A lightweight profiler, an Ames Engineering, Inc. LISA single laser unit, was received in February 2003 for the study. Based on the work done during the 2003 construction season, the following conclusions can be made: (1) For hot mix asphalt surfaces, the LISA correlated well with the contractors' profilographs; (2) LISA results are significantly affected by longitudinal tining on portland cement concrete pavements, requiring a laser system upgrade to give accurate results; (3) A significant time saving was realized by using the LISA; (4) Increasing visibility and reducing time in the construction zone improved safety; (5) One person with limited lifting capabilities could set up and operate the LISA; and (6) With the current Iowa Department of Transportation specification, the LISA cannot totally replace the profilograph, since bridges and short segments with no adjoining pavement would still require a profilograph.
Book Synopsis Real-time Smoothness Measurements on Portland Cement Concrete Pavements During Construction by : Robert Otto Rasmussen
Download or read book Real-time Smoothness Measurements on Portland Cement Concrete Pavements During Construction written by Robert Otto Rasmussen and published by Transportation Research Board. This book was released on 2013 with total page 143 pages. Available in PDF, EPUB and Kindle. Book excerpt: "TRB's second Strategic Highway Research Program (SHRP 2) Report S2-R06E-RR-1: Real-Time Smoothness Measurements on Portland Cement Concrete Pavements During Construction explores real-time smoothness measuring technologies for concrete paving. For the purposes of the report, real-time smoothness refers to measuring and evaluating the concrete pavement surface profile during construction along the paving train while the concrete surface is still wet. The report also includes draft suggested specifications and guidelines related to the use of technologies that allow paving crews to measure smoothness in real time. The results of Renewal Project R06E will be incorporated into an electronic repository for practitioners, known as the NDToolbox, which will provide information regarding recommended technologies for the detection of a particular deterioration. The NDToolbox is in the process of being created by SHRP 2 Renewal Project R06A, which has released SHRP 2 Report S2-R06A-RR-1: Nondestructive Testing to Identify Concrete Bridge Deck Deterioration that identifies nondestructive testing technologies for detecting and characterizing common forms of deterioration in concrete bridge decks. Renewal Project R06E, which produced SHRP 2 Report S2-R06E-RR-1, is one of seven follow-on projects to SHRP Renewal Project R06 that produced SHRP 2 Report S2-R06-RW: A Plan for Developing High-Speed, Nondestructive Testing Procedures for Both Design Evaluation and Construction Inspection, which examines existing and emerging nondestructive evaluation (NDE) technologies and their current state of implementation to satisfy the NDE needs for highway renewal."--Publisher description.

Book Synopsis Profile Equipment Evaluation by : E. G. Fernando
Download or read book Profile Equipment Evaluation written by E. G. Fernando and published by . This book was released on 1997 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Texas Department of Transportation (TxDOT) is implementing smoothness specifications based on profilograph testing as part of its construction quality control/quality assurance (QC/QA) program. Most tests are presently conducted using automated, California-type profilographs in which the equipment is pushed over a prescribed wheelpath. It appears that smoothness specifications will continue to be based on the profilograph, at least for the short term. However, in view of advances in profiling technology, it becomes prudent to investigate other methods of measuring surface profile and develop smoothness specifications based on profilers that offer greater accuracy and higher production rates. Already, a number of districts have expressed concerns about the sensitivity of the profilograph to short wavelengths or high frequency ripples. This observation demonstrates the need for more accurate measurements of surface profile for the purpose of building pavements that offer excellent ride quality, lower road user costs, and longer service lives. In pursuit of its goal of providing smooth pavements, TxDOT initiated a research project with the Texas Transportation Institute (TTI) to develop a smoothness specification for asphalt concrete overlays based on the new generation of pavement profilers that offer greater accuracy in profile measurement relative to the profilographs presently used in construction projects. Among other things, this research project evaluated a number of profile measuring devices to establish the availability of equipment for implementing a new profile-based smoothness specification in Texas. This report presents the findings of the profile equipment evaluation.

Book Synopsis Synthesis of Pavement Issues Related to High-speed Corridors by : Joe W. Button
Download or read book Synthesis of Pavement Issues Related to High-speed Corridors written by Joe W. Button and published by . This book was released on 2004 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this research project was to produce a synthesis of available information to support specific areas related to pavements for the safe, economical development of the Trans Texas Corridor (TTC). This synthesis is divided into nine sections, each of which deals with a specific topic or topics. These specific areas include (1) pavement design for heavy vehicles, (2) pavement design for light vehicles, (3) skid resistance issues on high-speed corridors, (4) issues related to traffic characterization, (5) smart pavements for high-speed corridors, (6) pavement material response to dynamic loads and performance prediction, (7) safety issues related to splash and spray, and (8) ride quality for high-speed corridors. Regarding these stated issues, this synthesis recommends state-of-the-art technology to the Texas Department of Transportation (TxDOT) for use during development of the TTC. It provides recommendations for future research to fill gaps in knowledge and to take emerging technology to the stage where it can be implemented during the design and construction of the TTC pavements. This is the first synthesis study to address issues related to the TTC. A secondary objective of this project was to determine if additional synthesis studies in other areas of transportation related to the TTC should be conducted and, if so, how the process might be improved. This synthesis recommends that future syntheses should be more focused on specific, maybe critical, issue(s); the researcher should be instructed to present only those findings that are really new, innovative, and potentially implementable. One element of the study should pursue non-transportation related technology that might be adapted to transportation issues.

Download or read book Measuring Pavement Profile at the Slip-form Paver written by and published by . This book was released on 2005 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pavement profile or smoothness has been identified nationally as a good measure of highway user satisfaction. This has led highway engineers to measure profiles of both operating and new highways. Operational highway profiles are often measured with high-speed inertial profilers. New highway profiles are usually measured with profilographs in order to establish incentives or disincentives for pavement construction. In most cases, these two processes do not measure the same value from the "cradle to grave" life of pavements. In an attempt to correct the inconsistency between measuring techniques, lightweight profilers intended to produce values to be used for construction acceptance are being made that measure the same profile as high-speed inertial profilers.

Available in PDF, EPUB and Kindle. Book excerpt: This report covers the activities that were performed to enhance the current Montana Department of Transportation (MDT) ride specification for flexible pavements. The project team reviewed the MDT ride specification for flexible pavements and compared it with current literature and state of practice. An extensive state of practice survey of other Departments of Transportation (DOTs) was conducted and the results were utilized to provide recommendations to MDT for improving its ride specification. This report provides detailed information on the review of MDT current ride specification, literature review, state of the practice survey, and recommendations for improvements. The recommendations cover the proposed improvements to the current ride specification, tolerances, project classification levels, analysis tools and indices, and methods of acceptance. As part of the recommendations, a series of new documents [i.e. Profiler Operations Manual, Quality Control/Quality Assurance (QC/QA) Plan] have been developed to enhance future profile data collection and analysis. Based on the findings of this project, the project team have revised the document entitled: Method of Sampling and Testing (MT 422) and the document: MDT Ride Specification For Flexible Pavement. An implementation plan has been developed and presented in this report to provide MDT with a road map for implementing the findings of this project.
