Moisture Damage in Asphalt Concrete
Author: Russell G. Hicks
Publisher: Transportation Research Board
ISBN: 9780309049245
Category : Technology & Engineering
Languages : en
Pages : 104
Book Description
This synthesis will be of interest to pavement designers, construction engineers, maintenance engineers, and others interested in avoiding or limiting moisture damage in asphalt concrete. Information is provided on physical and chemical explanations for moisture damage in asphalt concrete, along with a discussion of current practices and test methods for determining or reducing the susceptibility of various asphalt concrete components and mixtures to such damage. Moisture damage in asphalt concrete is a nationwide problem which often necessitates premature replacement of highway pavement surfaces. This report of the Transportation Research Board describes the underlying physical and chemical phenomena responsible for such damage. Current test methods used to determine the susceptibility of asphalt concretes, or their constituents, to moisture damage are described and evaluated. Additionally, current practices for minimizing the potential for moisture damage are examined.

An Assessment of Moisture Induced Damage in Asphalt Pavements

Languages : en
Pages : 164
Book Description
Abstract: Moisture-induced damage is one the major causes of deterioration of asphalt pavements and extensive research has been conducted on this topic. Theoretical and experimental results have led the researchers to believe that moisture-induced damages are caused mainly by the generation of pore water pressure in asphalt mixtures when traffic passes over a pavement. The Moisture Induced Sensitivity Tester (MIST) has been recently developed to simulate the phenomenon of repeated pore pressure generation and deterioration in the laboratory. The objective of this study was to evaluate moisture-induced damage in typical Maine Department of Transportation (DOT) asphalt mixes, with the use of MIST, pre and post testing, and analysis of data. The MIST was used to condition Hot Mix Asphalt (HMA) samples that were compacted from eight typical Maine DOT mixes, with different types of aggregates and asphalt binder. A modified Dynamic modulus test in Indirect Tensile Mode was used for the determination of damage. A layered elastic model, along with a fatigue-cracking criterion, was utilized to assess the total impact on the pavement lives. Monte Carlo analysis was conducted to determine the distribution of number of repetitions to failure of pavements that are subjected to moisture damage. The major conclusions are that most of the mixes are likely to experience a reduction in their life due to the effect of moisture and that the Micro-Deval and the fine aggregate absorption test results can be related to such damage. A composite factor, consisting of both of these test results, is recommended for regular use by the DOT to screen mixes with high moisture damage potential.

Rheometry of Pastes, Suspensions, and Granular Materials
Author: Philippe Coussot
Publisher: John Wiley & Sons
ISBN: 0471720569
Category : Technology & Engineering
Languages : en
Pages : 311
Book Description
A comprehensive examination of rheometry theory and its practical applications This publication enables readers to understand and characterize the flow properties of complex fluids and, with this knowledge, develop a wide range of industrial and consumer products. The author fills a gap in the current literature by presenting a comprehensive description of the rheological behavior of pastes, suspensions, and granular materials and by offering readers the rheometrical techniques needed to effectively characterize these materials. With his extensive experience in both academic and industrial research, the author is able to take the field to a new level in: * General schematic classification of the behavior of pastes,suspensions, and granular materials * Systematic review, analysis, and quantification of experimental problems with complex fluids * Insight into the flow behavior of complex fluids gained through the most recent discoveries and research techniques * Comprehensive rheometrical analysis of data obtained from research across a broad range of industries In addition to gaining a thorough understanding of the theory underlining rheometry, readers discover its many practical applications. Throughout the publication, specific examples are provided that illustrate how theory is applied, including examples involving food, civil engineering, cosmetics, pharmaceuticals, paper coatings, paint and ink, ceramics, sewage sludges, granular materials, and natural materials. In summary, this publication provides a comprehensive review of the behavior of pastes, suspensions, and granular materials as well as detailed analysis of rheometrical techniques. Everything needed to determine the behavior and movement of complex fluids is provided. It is, therefore, a recommended resource for rheologists, engineers, and researchers, as well as students who deal with complex fluids in product formulation, quality and process control, and process plant design.

Book Description
A technical review of moisture damage of asphalt pavements and antistripping additives has beencompleted as part of a review and testing study for the Transportation Association of Canada that has the objective of developing a Canadian manual on the assessment of moisture susceptibility and selection of antistripping additives. The review is based on practical asphalt technology experience, questionnaires to agencies and asphalt cement suppliers, and the technical literature on moisture damage of asphalt pavements. Methods of mitigating moisture damage in asphalt pavement structures, in addition to the use of antistripping additives, such as drainage, compaction, aggregates selection, mix designs and quality control, were reviewed in terms of stripping mechanisms and causes. The Strategic Highway Research Program has involved considerable research on the moisture susceptibility of asphalt concrete and appropriate laboratory procedures to assess moisture damage. Qualitative and quantitative (strength) tests for assessing the moisture susceptibility of hot-mix asphalt mixes are reviewed. There is strong technical support for the Tunnicliff-Root (ASTM D 4867), Modified Lottman (AASHTO T 283) and Ontario MTO Immersion Marshall (LS-283) tests. The use of liquid (amines generally) and hydrated lime antistripping additives is considered. There is considerable technical information on the comparative efficacy of hydrated lime as an antistripping additive. An important area of research need is appropriate quality control/quality assurance to monitor the field effectiveness of antistripping additives. For the covering abstract of this conference see IRRD number 872978.
