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: 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.

Available in PDF, EPUB and Kindle. Book excerpt: Surface characteristics represent a critical issue facing pavement owners and the concrete paving industry. The traveling public has come to expect smoother, quieter, and better drained pavements, all without compromising safety. The overall surface characteristics issue is extremely complex since all pavement surface characteristics properties, including texture, noise, friction, splash/spray, rolling resistance, reflectivity/illuminance, and smoothness, are complexly related. The following needs and gaps related to achieving desired pavement surface characteristics need to be addressed: determine how changes in one surface characteristic affect, either beneficially or detrimentally, other characteristics of the pavement, determine the long-term surface and acoustic durability of different textures, and develop, evaluate, and standardize new data collection and analysis tools. It is clear that an overall strategic and coordinated research approach to the problem must be developed and pursued to address these needs and gaps.

Download or read book Measurement of Pavement Smoothness for Construction Quality Control written by and published by . This book was released on 1992 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This research study of pavement smoothness measurement was conducted in order to develop and implement an improved highway smoothness construction specification on asphalt concrete pavements. Achieving a higher level of smoothness on highways during construction results in savings to the taxpayer due to reduced wear and tear on vehicles, and longer highway life. Although the current ADOT specification used for highway smoothness addresses localized smoothness problems, it is difficult to administer due to the measurement system used, and provides little impetus to the contractor to improve his quality of work with respect to overall highway smoothness. This study provided data to assist ADOT in developing a new smoothness specification that would provide incentive to contractors to construct smoother pavements and which is easier for ADOT to administer. In order to provide incentive to contractors, a pavement smoothness construction quality control draft specification and associated measurement procedure was produced.

Download or read book Measuring Characterizing and Reporting Pavement Roughness of Low speed and Urban Roads written by Steven M. Karamihas and published by . This book was released on 2019 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pavement smoothness (or roughness) is used by state highway agencies for monitoring network condition and other purposes such as assessing construction quality and optimizing investments in preservation, rehabilitation, and reconstruction. States are also required to report the International Roughness Index (IRI) as an element of the federal Highway Performance Monitoring System (HPMS). Because IRI is not measured directly but is calculated as the mechanical response of a generic quarter-car, traveling at 50 mph, to the elevation profile of the roadway, there are concerns about using current practices for estimating roughness of low-speed and urban roads. Because of the unique features of low-speed and urban roads, research was needed to identify or, if necessary, develop means for appropriately measuring, characterizing and reporting pavement roughness of these roads. National Cooperative Highway Research Program (NCHRP) Research Report 914: Measuring, Characterizing, and Reporting Pavement Roughness of Low-Speed and Urban Roads reviews the practices for roughness measurement and the unique features of urban and low-speed roadways, and it evaluates the use of existing inertial profilers for such measurements. The report also proposes revisions to American Association of State Highway and Transportation Officials standard specifications and practices addressing inertial profiler certification and operations.

This book was released on 1991 with total page 55 pages. Available in PDF, EPUB and Kindle. Book excerpt: Because both the highway agency and the traveling public desire a smooth pavement surface, there exists a need to ensure smoothness and ride quality. Indeed, a smooth road profile has become a standard measure of pavement quality. This report details the initial work on pavement smoothness criteria, including in particular the issues related to financial incentives and the instrumentation used for measuring profiles on newly laid rigid pavements.

Download or read book Measuring and Specifying Pavement Smoothness written by United States. Federal Highway Administration and published by . This book was released on 2016 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: Smoothness is a measure of the level of comfort experienced by the traveling public while riding over a pavement surface. As an important indicator of pavement performance, smoothness is used interchangeably with roughness as an expression of the deviation of a surface from a true planar surface (as defined by ASTM E867) and is often cited as the most important indicator of user satisfaction. However, smoothness also imparts a number of other benefits, including improved pavement performance and service life, improved safety, and reduced fuel and vehicle maintenance cost (Smith et al. 1997; FHWA 2006; Chatti and Zaabar 2012; Van Dam et al. 2015). In recognition of the importance of pavement smoothness, many highway agencies employ specifications to control initial pavement smoothness during construction and then monitor it over time as an indicator of performance and as a trigger for maintenance or rehabilitation. The purpose of this Tech Brief is to describe the tools and techniques used to measure and express pavement smoothness.

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.
