Book Synopsis Measurement of Aggregate Texture and Its Influence on Hot Mix Asphalt (HMA) Permanent Deformation by : T. Fletcher
Download or read book Measurement of Aggregate Texture and Its Influence on Hot Mix Asphalt (HMA) Permanent Deformation written by T. Fletcher and published by . This book was released on 2002 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aggregate shape has a significant effect on the performance of asphalt mixes. Designing well-performing asphalt pavements requires developing methods to quantify rapidly and accurately the different aggregate shape properties, and most importantly, relate these properties to performance. Aggregate texture has been identified in several studies to be the shape property that has the most significant influence on asphalt mix performance. This study presents a new procedure for measuring aggregate texture using image analysis techniques. The main advantages of this new procedure are the ability to capture the different sizes of texture elements, to separate the true texture from the color variations on the aggregate surface, and to characterize both fine and coarse aggregates. The procedure is used to measure texture for a wide range of fine and coarse aggregates, and the results are compared with the laboratory performance of asphalt mixes. The analysis shows that the procedure yields detailed information on aggregate texture in a short time. The texture measurements have very good correlation with the resistance of asphalt mixes to permanent deformation measured in the laboratory using different wheel tracking devices.

Book Synopsis Quantification of Coarse Aggregate Shape and Its Effect on Engineering Properties of Hot-Mix Asphalt Mixtures by : J-S Chen
Download or read book Quantification of Coarse Aggregate Shape and Its Effect on Engineering Properties of Hot-Mix Asphalt Mixtures written by J-S Chen and published by . This book was released on 2001 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper is aimed at quantifying coarse aggregate shape in an efficient manner and relating aggregate characteristics to mix properties. Digital image analysis was used to evaluate aggregate characteristics such as elongation, flatness, and other shape indices. The following particle shapes were selected for this study: cubical, rod, disk, and blade. Data showed that the morphological characteristics of coarse aggregate correlated well with the results of other indirect tests such as the particle index. Cubical particles possessed the best rutting resistance over the other shapes. Flaky and/or elongated aggregate in a mixture resulted in a lower resistance to shear deformation. The morphological characteristics of coarse aggregates found from image analysis were in good agreement with the engineering properties of hot-mix asphalt (HMA) mixtures. This paper presents a precise method to evaluate the aggregate characteristics in an HMA mix and demonstrates their effects on pavement performance.
Book Synopsis DSC/HISS Modeling Applications for Problems in Mechanics, Geomechanics, and Structural Mechanics by : Chandrakant S. Desai
Download or read book DSC/HISS Modeling Applications for Problems in Mechanics, Geomechanics, and Structural Mechanics written by Chandrakant S. Desai and published by CRC Press. This book was released on 2023-11-30 with total page 459 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding the mechanical behavior of solids and contacts (interfaces and joints) is vital for the analysis, design, and maintenance of engineering systems. Materials may simultaneously experience the effects of many factors such as elastic, plastic, and creep strains; different loading (stress) paths; volume change under shear stress; and microcracking leading to fracture and failure, strain softening, or degradation. Typically, the available models account for only one factor at a time; however, the disturbed state concept (DSC) with the hierarchical single-surface (HISS) plasticity is a unified modeling approach that can allow for numerous factors simultaneously, and in an integrated manner. DSC/HISS Modeling Applications for Problems in Mechanics, Geomechanics, and Structural Mechanics provides readers with comprehensive information including the basic concepts and applications for the DSC/HISS modeling regarding a wide range of engineering materials and contacts. Uniformity in format and content of each chapter will make it easier for the reader to appreciate the potential of using the DSC/HISS modeling across various applications. Features: • Presents a new and simplified way to learn characterizations and behaviors of materials and contacts under various conditions • Offers modeling applicable to several different materials including geologic (clays, sands, rocks), modified geologic materials (structured soils, overconsolidated soils, expansive soils, loess, frozen soils, chemically treated soils), hydrate-bearing sediments, and more.

Book Synopsis 7th RILEM International Conference on Cracking in Pavements by : A. Scarpas
Download or read book 7th RILEM International Conference on Cracking in Pavements written by A. Scarpas and published by Springer Science & Business Media. This book was released on 2012-08-30 with total page 1340 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the recent past, new materials, laboratory and in-situ testing methods and construction techniques have been introduced. In addition, modern computational techniques such as the finite element method enable the utilization of sophisticated constitutive models for realistic model-based predictions of the response of pavements. The 7th RILEM International Conference on Cracking of Pavements provided an international forum for the exchange of ideas, information and knowledge amongst experts involved in computational analysis, material production, experimental characterization, design and construction of pavements. All submitted contributions were subjected to an exhaustive refereed peer review procedure by the Scientific Committee, the Editors and a large group of international experts in the topic. On the basis of their recommendations, 129 contributions which best suited the goals and the objectives of the Conference were chosen for presentation and inclusion in the Proceedings. The strong message that emanates from the accepted contributions is that, by accounting for the idiosyncrasies of the response of pavement engineering materials, modern sophisticated constitutive models in combination with new experimental material characterization and construction techniques provide a powerful arsenal for understanding and designing against the mechanisms and the processes causing cracking and pavement response deterioration. As such they enable the adoption of truly "mechanistic" design methodologies. The papers represent the following topics: Laboratory evaluation of asphalt concrete cracking potential; Pavement cracking detection; Field investigation of pavement cracking; Pavement cracking modeling response, crack analysis and damage prediction; Performance of concrete pavements and white toppings; Fatigue cracking and damage characterization of asphalt concrete; Evaluation of the effectiveness of asphalt concrete modification; Crack growth parameters and mechanisms; Evaluation, quantification and modeling of asphalt healing properties; Reinforcement and interlayer systems for crack mitigation; Thermal and low temperature cracking of pavements; and Cracking propensity of WMA and recycled asphalts.
