Book excerpt: The primary product of this study was a demonstration performance -related specification (PRS) system for PCC pavement construction. The system is designed to consider three key factors (ie, PCC strength, slab thickness and initial serviceability) in assessing an as-constructed pavement delivered by a contractor and calculating an appropriate reward (bonus/incentive) or penalty (disincentive). Many pavement performance prediction relationships and PCC property prediction equations were evaluated to develop the performance-related aspects of the new system. In addition, a rather intensive experimental laboratory study of PCC material properties was conducted to develop better multi-factor prediction relationships. The demonstration PRS was developed using a computerized spreadsheet program.

Available in PDF, EPUB and Kindle. Book excerpt: The goal in highway construction and operation has shifted from method based specifications to specifications relating desired performance attributes to materials, mix designs, and construction methods. Shifting from method specifications to performance based specifications can work as an incentive or disincentive for the contractor to improve performance or extend pavement life. This literature search was directed at a review of existing portland cement concrete performance specification development, and the criteria that can effectively measure pavement performance. The criteria identified in the literature include concrete strength, slab thickness, air content, initial smoothness, water-cement ratio, unit weight, and slump. A description of each criterion, along with the advantages, disadvantages, and test methods for each are identified. Also included are the results from a survey that was sent out to various state, federal, and trade agencies. The responses indicated that 53% currently use or are developing a performance based specification program. Of the 47% of agencies that do not use a performance based specification program, over 34% indicated that they would consider a similar program. The most commonly measured characteristics include thickness, strength, smoothness, and air content. Lastly recommendations and conclusions are made regarding other factors that affect pavement performance and a proposed second phase of the research is suggested. The research team suggests that a regional expert task group be formed to identify performance levels and criteria. The results of that effort will guide the research team in the development of new or revised specifications.

This book was released on 2004-01-01 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Performance-Related Specifications (PRS) are specifications that base pavement acceptance and pay adjustment on the projected performance and predicted life-cycle cost (LCC) for a specific pavement. PRS relate measurable quality characteristics with pavement performance through computer simulations that incorporate physical distress models. Previously, work at ERES consultants by Darter and co-workers developed prototype PRS for jointed plain portland cement concrete pavements (PCC) through Federal Highway Administration (FHWA) through a series of research projects. However, before this research program began, pavements have not been constructed using these specifications. This report describes the Indiana Department of Transportation’s (INDOT) experience with developing and implementing the first and second Level 1 PRS projects during the re-construction of a portion of I-465 east of Indianapolis and I-65 north of Clarksville, respectively. This report includes an overview of the concepts behind PRS, the process of developing a Level 1 PRS, lessons learned from implementing the first PRS in the construction of the pavement outside Indianapolis during the summer of 2000, lessons learned from implementing the second PRS in the construction of the pavement outside Clarksville during the summer of 2002, the use of non-destructive testing procedures to obtain measures of pavement quality, sample specifications, and conclusions and recommendations. In general, this specification was well received by both the agency and the contractors. It is believed that lessons learned on these projects will enable future modifications to the development of performance related specifications with the hope that these specifications will enable longer lasting, more cost effective pavements to be constructed.

Download or read book Performance Based Specifications and Control of Concrete Durability written by Hans Beushausen and published by Springer. This book was released on 2015-09-24 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work gives an overview of significant research from recent years concerning performance-based design and quality control for concrete durability and its implementation. In engineering practice, performance approaches are often still used in combination with prescriptive requirements. This is largely because, for most durability test methods, sufficient practical experience still has to be gained before engineers and owners are prepared to fully rely on them. This book, compiled by RILEM TC 230-PSC, is intended to assist efforts to successfully build the foundation for the full implementation of performance-based approaches through the exchange of relevant knowledge and experience between researchers and practitioners worldwide.

This book was released on 2007 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: The primary objective of this study was to develop, implement, and evaluate a Level 1 performance-related specification (PRS) for the construction of a jointed plain concrete (JPC) pavement in the State of Wisconsin. The research entailed a thorough evaluation of the construction quality levels achieved on recent Wisconsin JPC projects and the formulation of a Level 1 PRS using the results of the quality evaluation and defined Wisconsin Department of Transportation (WisDOT) pavement practices as a basis. Feedback from WisDOT and the contractor indicated that this first PRS implementation in Wisconsin was successful, particularly with respect to the layouts of lots and sublots. Several suggestions were received to improve and streamline the PRS process.

Download or read book Concrete Mix Design Quality Control and Specification Fourth Edition written by Ken W. Day and published by CRC Press. This book was released on 2013-11-11 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: The nature of concrete is rapidly changing, and with it, there are rising concerns. Thoroughly revised and updated, this fourth edition of Concrete Mix Design, Quality Control and Specification addresses current industry practices that provide inadequate durability and fail to eliminate problems with underperforming new concrete and defective testing. Many specifications now require additional criteria in an attempt to improve durability or other properties. This book discusses the trend towards adding performance requirements to existing prescriptive specifications. It also explores the matter of prescription versus performance specification and especially the specification of non-strength-related performance such as durability. What’s new in the Fourth Edition: Examines water-to-cement ratio as a declining criterion of quality and durability Discusses the diminishing availability of suitable natural sands and growing industry concerns regarding the environmental impact of their use Considers advances in concrete admixtures and their ever-increasing use Advocates reliability of testing as a vital feature of the shift from prescriptive to performance specifications Addresses cement replacement materials as they relate to greenhouse gas and sustainability Concrete Mix Design, Quality Control and Specification explores producing, designing, controlling, or specifying concrete, and addresses issues related with sustainability and the impact of new concrete materials such as ready mixed geopolymers, magnesium oxide, and calcium carbonate. The text is an ideal resource for concrete technologists, producers and specifiers, and contractors on large projects
