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.

Download or read book Petrographic Atlas: Characterisation of Aggregates Regarding Potential Reactivity to Alkalis written by Isabel Fernandes and published by Springer. This book was released on 2016-03-18 with total page 198 pages. Available in PDF, EPUB and Kindle. Book excerpt: This RILEM AAR 1.2 Atlas is complementary to the petrographic method described in RILEM AAR 1.1. It is designed and intended to assist in the identification of alkali-reactive rock types in concrete aggregate by thin-section petrography. Additional issues include: • optical thin-section petrography conforming to RILEM AAR 1.1 is considered the prime assessment method for aggregate materials, being effective regarding cost and time. Unequivocal identification of minerals in very-fine grained rock types may however require use of supplementary methods. • the atlas adheres to internationally adopted schemes for rock classification and nomenclature, as recommended in AAR 1.1. Thus, rock types are classified as igneous, sedimentary or metamorphic based upon mineral content, microstructure and texture/fabric. • in addition, the atlas identifies known alkali-reactive silica types in each rock type presented. It also identifies consistent coincidence between certain lithologies and silica types; however, it refrains from attributing alkali-reactivity to a specific silica property or quality. • operator skill and experience remain essential for reliable assessment by thin-section petrography. • aggregate materials must be classified according to local criteria, based on regional experiences with ASR-damaged field structures and geology. Access to additional data may be relevant for the assessment of imported materials. • mere application of rock nomenclature does not provide any sort of warranty to the development of deleterious alkali-reaction. Such may result in either rejection of a suitable aggregate material, thus wasting a valuable resource, or acceptance of an unsuitable material leading to concrete damage, both of which are undesirable.

This book was released on 2015-09-30 with total page 181 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains the full set of RILEM Recommendations which have been produced to enable engineers, specifiers and testing houses to design and produce concrete which will not suffer damage arising from alkali reactions in the concrete. There are five recommended test methods for aggregates (designated AAR-1 to AAR-5), and an overall recommendation which describes how these should be used to enable a comprehensive aggregate assessment (AAR-0). Additionally, there are two Recommended International Specifications for concrete (AAR-7.1 & 7.2) and a Preliminary International Specification for dams and other hydro structures (AAR-7.3), which describe how the aggregate assessment can be combined with other measures in the design of the concrete to produce a concrete with a minimised risk of developing damage from alkali-aggregate reactions.

This book was released on 2007 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: The primary objective of this project was to examine the effects of poor quality coarse limestone aggregate on hotmix asphalt performance and to determine how much of the poor quality limestone can be used before adversely affecting performance. A Type C aggregate composed of a high quality limestone from one quarry was blended with soft and absorptive limestone aggregates from two other quarries in different proportions using a PG 64-22 asphalt binder. The individual aggregates were run through Los Angles abrasion, Micro-Deval, magnesium sulfate soundness, specific gravity, and absorption tests. Molded bituminous samples were tested with the Hamburg wheel tracker, dynamic modulus, and the overlay tester.

Download or read book Criminal and Environmental Soil Forensics written by Karl Ritz and published by Springer Science & Business Media. This book was released on 2008-12-23 with total page 534 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soils have important roles to play in criminal and environmental forensic science. Since the initial concept of using soil in forensic investigations was mooted by Conan Doyle in his Sherlock Holmes stories prior to real-world applications, this branch of forensic science has become increasingly sophisticated and broad. New techniques in chemical, physical, biological, ecological and spatial analysis, coupled with informatics, are being applied to reducing areas of search by investigators, site identification, site comparison and measurement for the eventual use as evidence in court. Soils can provide intelligence, in assisting the determination of the provenance of samples from artifacts, victims or suspects, enabling their linkage to locations or other evidence. They also modulate change in surface or buried cadavers and hence affect the ability to estimate post-mortem or post-burial intervals, and locate clandestine graves. This interdisciplinary volume explores the conceptual and practical interplay of soil and geoforensics across the scientific, investigative and legal fields. Supported by reviews, case-studies from across the world, and reports of original research, it demonstrates the increasing convergence of a wide range of knowledge. It covers conceptual issues, evidence (from recovery to use in court), geoforensics, taphonomy, as well as leading-edge technologies. The application of the resultant soil forensics toolbox is leading to significant advances in improving crime detection, and environmental and national security.
