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 1998 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: The maintenance and upgrading of our built environment, including large sections of coastal defences, relies heavily on natural construction materials. The text aims to highlight a range of pressing research issues in natural construction materials of direct relevance to an industry facing growing pressures for environmental sustainability and standardization of product quality within Europe. Tests and specifications given in the forthcoming Eurostandards for aggregates and armourstones are considered and correlated with older more widely used tests, including those which could impact upon current road safety. This text should be useful to: aggregate and amourstone suppliers and users; civil and engineering geologists; quarry companies; and Local and County Authority engineers and coastal engineers.

This book was released on 1999 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many tests have been developed to empirically characterize aggregate without necessarily strong relationships with the performance of final products incorporating these aggregates. This seems to be particularly true for "toughness and abrasion resistance" and "durability and soundness." Toughness/abrasion resistance and durability/soundness of aggregate are correlated, but represent resistance to degradation when subject to mechanical forces and weathering, respectively. A literature review identified five toughness/abrasion resistance and four durability/soundness test procedures. Sixteen aggregates with a wide range of properties were tested with eight of the identified test procedures. Results from the tests and test precisions were compared.

This book was released on 2007 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: A strong correlation was identified between UCS after the freeze-thaw test and UCS after the vacuum saturation test, while very weak correlations were observed between the final dielectric value after tube suction testing and all other response variables. Differences in variability between test results were determined to be statistically insignificant.

Download or read book Evaluation of the Effect of Aggregate Properties of Samples Extracted Using the Ignition Furnace written by Brian D. Prowell and published by . This book was released on 2000 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Superpave mix design system includes four consensus aggregate properties to ensure aggregate quality: coarse aggregate angularity, flat and elongated particles, fine aggregate angularity, and sand equivalent. In addition to determining these consensus aggregate properties, ascertaining aggregate gradations and specific gravities are also required to complete an optimal mix design. A method of extracting the asphalt from recycled asphalt pavement (or from quality control/quality assurance samples) that would produce a clean aggregate sample for analysis was needed. VDOT has used the ignition method for determining asphalt content and for the recovery of aggregates for gradation analysis since 1995. This study evaluated the effect on aggregate properties of samples extracted using the ignition furnace. For the purposes of the study, recycled asphalt pavement was artificially produced by mixing virgin aggregates with asphalt and aging the mixture prior to extraction in the ignition furnace. Consensus aggregate properties, specific gravity tests, and gradation analysis were performed on three replicates each of the virgin and recovered aggregates. Only the sand equivalent test and aggregate-specific gravities showed regular significant differences. It was found that the specific gravity values measured for aggregates recovered using the ignition furnace were closer to the measured values for the virgin aggregates than the effective specific gravity method which has been traditionally used for estimating a bulk gravity for recycled asphalt pavement. As a result of this study, recommendations were made to the Virginia Department of Transportation to change testing requirements on recycled asphalt pavement.

This book was released on 2024-08-28 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: Global warming, caused by a significant increase in the concentration of greenhouse gases (GHGs) such as CO2, has become a concern all over the world. The whole process carbon emissions of the civil engineering industry account for nearly 40% of global energy and process-related CO2 emissions, more than half of which come from the process of producing, using, constructing and dismantling in civil engineering materials and structures, resulting in the embodied carbon emissions. With the acceleration of global warming, warmer and uncertain climates will make engineering materials and structures subject to more severe environmental conditions. A series of durability issues will occur more frequently, such as the significant variations of humidity in air, the chloride-induced corrosion caused by the severe chloride ingress, concrete cracking caused by the expansion of rusts, and more severe carbonation of concrete structures due to the increase in CO2 concentration. The adoption of positive measures to address climate change has become a global consensus, as global warming has led to serious threats and challenges to the survival and development of humankind.
