Download or read book Comparing the Volumetric and Mechanical Properties of Laboratory and Field Specimens of Asphalt Concrete written by Louay Nadhim Mohammad and published by . This book was released on 2016 with total page 77 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.

Download or read book Asphaltic Concrete Construction written by National Research Council (U.S.). Highway Research Board and published by . This book was released on 1960 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: Paper 1: The broad gap between research on asphaltic concrete specimens prepared in laboratory bench-type equipment and test roads or public highways has been narrowed by providing full-scale paving equipment in a research facility. This facility permits asphaltic concrete pavement construction under conditions of control which cannot be reached in field operations. Paper 2: Laboratory and field data have been collected from 12 regular contract hot-mix asphaltic concrete paving projects in various areas of Texas for the purpose of comparing laboratory and field densities. Paper 3 proposes a mechanism by which mixes can be unstable at high temperatures during rolling and still be quite stable by normal design criteria.
