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.

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.

Download or read book Variability in Highway Pavement Construction written by Charles S. Hughes and published by Transportation Research Board. This book was released on 1996 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: This synthesis will be of interest to state DOT construction, materials, statistical, specification, and inspection engineers; DOT research staff; pavement construction material suppliers; highway construction contractors; and civil engineering consulting firms, including field and laboratory materials testing personnel. The synthesis describes the state of the practice for defining and measuring variability in highway pavement construction. Data obtained from a review of the literature, a survey of state departments of transportation (DOTs), and discussions with selected state DOT personnel and private materials producers are presented. This report of the Transportation Research Board defines several measures of variability but concentrates on the use of standard deviation as the usual measure of variability. The synthesis updates reported typical variabilities found in materials and construction specifications. Also included are discussions of current research activities as related to variability, how variability can be used in the development of specification limits, the use of incentives and disincentives in specifications, and the need for additional information on the variability of several materials and construction processes.

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 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.

Download or read book Concrete Pavement Design Construction and Performance written by Norbert Delatte and published by CRC Press. This book was released on 2018-10-08 with total page 391 pages. Available in PDF, EPUB and Kindle. Book excerpt: Addressing the interactions between the different design and construction variables and techniques this book illustrates best practices for constructing economical, long life concrete pavements. The book proceeds in much the same way as a pavement construction project. First, different alternatives for concrete pavement solutions are outlined. The desired performance and behaviour parameters are identified. Next, appropriate materials are outlined and the most suitable concrete proportions determined. The design can be completed, and then the necessary construction steps for translating the design into a durable facility are carried out. Although the focus reflects highways as the most common application, special features of airport, industrial, and light duty pavements are also addressed. Use is made of modeling and performance tools such as HIPERPAV and LTPP to illustrate behavior and performance, along with some case studies. As concrete pavements are more complex than they seem, and the costs of mistakes or of over-design can be high, this is a valuable book for engineers in both the public and private sectors.
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.
