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 1993, the Colorado Department of Transportation (CDOT) recognized that specifying HBP volumetric properties would likely provide superior pavements. A long range goal was set for acceptance to be based on voids properties. Beginning in 1993, a series of void acceptance (VA) pilot projects were let to contract; by the end of 1996, nine had been completed. Six had conventional mix designs. The last three were designed using Superpave technology. The data for the nine VA projects are summarized and compared with data from concurrent CDOT projects under Quality Level Analysis (QLA).

Download or read book HBP Pilot Void Acceptance Projects in Region 2 in 1997 written by Bud A. Brakey and published by . This book was released on 1998 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: Summaries and analyses of three Void Acceptance (VA) projects are reported and compared with previous VA and quality assurance and quality control (QA & QC) projects. For two of the three projects, the voids filled with asphalt (VFA) averaged 77% (design criteria was 65-75%) and percent air voids (AV) averaged 3.2% (design target was 4.0%). Because compacted bulk specific gravity field tests were higher than lab-mixed design values, for all processes, field AV and voids in mineral aggregate (VMA) averaged 0.4% below design values. VMA was easily met after field targets were adjusted.

This book was released on 2016 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: This reports document research that was performed to (1) determine causes of variability and tolerances for volumetric and mechanical properties of dense-graded asphalt mixtures measured within and among the three specimen types; and (2) propose a practice for state departments of transportation to incorporate these results in specifications and criteria for quality assurance, mix design verification or validation, and structural design and forensic studies. The research was conducted in two phases. In Phase I, datasets of laboratory and field test data were collected and pooled in a meta-analysis in an attempt to determine levels of variability in asphalt mixtures and the factors causing variability among and between the three specimen types. Despite the inclusion of 25 extensive datasets representing roughly 8,000 individual mixtures in the meta-analysis, the results of the analysis were inconclusive. Phase II was then undertaken--a program testing specimens from paving projects across the United States to quantify the effects of process-based factors on the variability of volumetric and mechanical properties of the specimen types. The key outcome of the research is a proposed practice for evaluating the cause and magnitude of variability within and among the three specimen types. In addition, tolerances of volumetric and conversion factors between the three specimen types of mechanical properties evaluated are proposed based on the average difference between specimen comparisons for the mixtures evaluated in Phase II. Agencies may use these proposed values to evaluate and adjust their current tolerances.
