Available in PDF, EPUB and Kindle. Book excerpt: This report presents an evaluation of the 4-cycle magnesium sulfate soundness test to control quality of coarse aggregates for use in hot mix asphaltic concrete and seal coats. A total of 41 aggregates were tested for the purpose of this study in the laboratory and the behavior of eight of the aggregates was evaluated in the field by examining roadway performance. The soundness test was found to be the best method for predicting performance among specific gravity, absorption, aggregate durability index, freeze-thaw, Los Angeles abrasion, and a modified Texas wet ball mill (called Texas degradation) tests. Specific recommendations have been suggested to improve the soundness procedure. Also specification limits for hot mix and seal coat projects have been included.
Download or read book Guidelines for Concrete Mixtures Containing Supplementary Cementitious Materials to Enhance Durability of Bridge Decks written by John S. Lawler and published by Transportation Research Board. This book was released on 2007 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: NCHRP Report 566 is designed to help facilitate the use of supplementary cementitious materials to enhance durability of concrete used in highway construction, especially bridge decks. The report includes a methodology for selecting optimum concrete mixture proportions that focuses on durability aspects of concrete and the performance requirements for specific environmental conditions. The methodology is presented in a text format and as a computational tool, in the form of a Visual Basic?driven Microsoft Excel spreadsheet. Background information and a hypothetical case study was published as NCHRP Web-Only Document 110: Supplementary Cementitious Materials to Enhance Durability of Concrete Bridge Decks. The Statistical Experimental Design for Optimizing Concrete (SEDOC), the computational tool for the concrete mixture optimization methodology, and the user?s guide are available in a ZIP format for download.

This book was released on 2007 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aggregates used in the construction of roads must be durable, abrasion resistant, and freeze thaw resistant in order to perform well in pavement or as base course. The objective of this study was to investigate whether the Micro Deval test will provide better, timelier, and more repeatable information about the quality of an aggregate than the Sodium Sulfate Soundness test. This objective was met by (1) conducting a thorough literature review, (2) testing a variety of soils from across Montana, and (3) analyzing these results to reveal potential trends. The literature review indicated that the Micro Deval test has good repeatability characteristics, and that it correlates well to field performance. Laboratory tests (Micro Deval, L.A. Abrasion, and Sodium Sulfate) were conducted on a variety of soil types to examine the repeatability of each test method, and to examine how well the methods correlate with each other in terms of predicting aggregate durability and degradation. Test results were normalized to facilitate direct comparisons between the three methods. Linear regression of the data points and corresponding confidence intervals were plotted to qualitatively assess agreement or disagreement between test methods. The authors concluded that the Micro Deval test is a suitable replacement for the Sodium Sulfate test as the primary method for evaluating aggregate durability, with limitations. Because there were some inconsistent durability determinations between test methodologies, the authors recommend that the Micro-Deval test results be further supported by a second aggregate durability test whenever the Micro Deval results fall between the cutoff value and plus 30 percent of the cutoff value. In other words, when the Micro Deval test result for an aggregate is between 18 and 24 percent loss, a second test using an alternate method is recommended before any conclusions are made regarding the durability or quality of an aggregate.

Available in PDF, EPUB and Kindle. Book excerpt: Throughout its long history, sulfate soundness testing of aggregates has been frequently cited for poor reliability as a predictor of concrete durability. However, its use remains widespread, even to the point of constituting an acceptance test criterion for aggregates. Sodium sulfate soundness tests of coarse aggregates are compared in this paper with freezing and thawing tests of air-entrained concretes containing the aggregates. In one case, sodium sulfate soundness displayed a relationship to durability (freezing and thawing) test results, in a statistical sense, but the level of predictability was poor. In another test series, the level of predictability fell within the range of pure chance.
