This book was released on 2013 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: Approximately 10 to 11 million tons of aggregates are utilized in transportation infrastructure projects in Wisconsin annually. The quality of aggregates has a tremendous influence on the performance and durability of roadways and bridges. In this Phase II research study, detailed statistical analyses were performed on over 1,000 sets of historical aggregate test results and the experimental results from the Phase I study. Test results from other states were analyzed as well. Aggregate tests were performed on 12 known marginal or poor Wisconsin aggregates to specifically address test performance of such aggregates. Selected aggregates were scanned using X-ray computed tomography to assess the effects of freeze-thaw and sodium sulfate exposure on the internal void system. The results of multi-parameter logistic regression analyses show that the pass/fail outcomes of the Micro-Deval test can be predicted when LA abrasion, absorption, and sodium sulfate soundness test results are known. The unconfined freeze-thaw test outcomes cannot be predicted from results of other tests (not correlated). Therefore, the unconfined freeze-thaw test should be part of any test protocol as it measures an aggregate characteristic that cannot be obtained from other tests. The percentiles associated with any proposed acceptance threshold limits for various aggregate tests should be determined using the statistical data provided.

This book was released on 2007 with total page 135 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this research project was to improve current practice by investigating different test methods to quantify moisture damage in an effort to serve the short and long term needs of the agency and industry. In the short term, more efficient test methods were investigated for use as a screening test to supplement current testing procedures. The Stripping Test was chosen as a candidate to serve this need. This test measures the mass loss due to moisture conditioning of a HMA loose mix. The test was evaluated in terms of serving as a screening test to waive mechanical testing requirements for mixes that display resistance to moisture damage.

Download or read book The Effect of Deicing Salt on Aggregate Durability written by Wendell G. Dubberke and published by . This book was released on 1985 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since 1962, the Iowa DOT has been using the methods of rapid freezing in air and thawing in water to evaluate coarse aggregate durability in concrete. Earlier research had shown that the aggregate pore system was a major factor in susceptibility to D-cracking rapid deterioration. There are cases in which service records indicate that on heavily salted primary roads, concrete containing certain aggregates show rapid deterioration while the same aggregates show relatively good performance on secondary roads with limited use of deicing salt. A fivecycle salt treatment of the coarse aggregate before durability testing has yielded durability factors that correlate with aggregate service records on heavily salted primary pavements. X-ray fluorescence analyses have shown that sulfur contents correlate well with aggregate durabilities with higher sulfur contents that produce poor durability. Trial additives affecting the salt treatment durabilities would indicate that one factor in the rapid deterioration mechanism is an adverse chemical reaction. The objective of the current research is to develop a simple method of determining aggregate susceptibility to salt-related deterioration. This method of evaluation includes analyses of both the pore system and chemical composition.

Download or read book Use of the Micro Deval Test for Assessing the Durability of Virginia Aggregates written by M. Shabbir Hossain and published by . This book was released on 2007 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aggregate is one of the most widely used construction material, and the key aspect of aggregate quality is durability. In this study, the Micro-Deval test, a new test developed in France and modified by Canadians, was studied to evaluate its suitability in assessing the durability of coarse and fine aggregates from Virginia sources. The Micro-Deval and several known aggregate tests were compared. The Micro-Deval test showed a very high potential in evaluating aggregate durability with higher precision and accuracy than the conventional tests such as the magnesium sulfate and Los Angeles abrasion tests. The Micro-Deval test was able to differentiate between good and poor performing aggregates at least 70 percent of the time and was able to identify the quality difference between similar aggregate types with varying degrees of weathering. Because of the study findings, the researchers recommend that the Micro-Deval test be used as a quality control tool for aggregate assessment to supplement the current measures of aggregate quality.
