This book was released on 2019-08-21 with total page 2435 pages. Available in PDF, EPUB and Kindle. Book excerpt: Advances in Engineering Materials, Structures and Systems: Innovations, Mechanics and Applications comprises 411 papers that were presented at SEMC 2019, the Seventh International Conference on Structural Engineering, Mechanics and Computation, held in Cape Town, South Africa, from 2 to 4 September 2019. The subject matter reflects the broad scope of SEMC conferences, and covers a wide variety of engineering materials (both traditional and innovative) and many types of structures. The many topics featured in these Proceedings can be classified into six broad categories that deal with: (i) the mechanics of materials and fluids (elasticity, plasticity, flow through porous media, fluid dynamics, fracture, fatigue, damage, delamination, corrosion, bond, creep, shrinkage, etc); (ii) the mechanics of structures and systems (structural dynamics, vibration, seismic response, soil-structure interaction, fluid-structure interaction, response to blast and impact, response to fire, structural stability, buckling, collapse behaviour); (iii) the numerical modelling and experimental testing of materials and structures (numerical methods, simulation techniques, multi-scale modelling, computational modelling, laboratory testing, field testing, experimental measurements); (iv) innovations and special structures (nanostructures, adaptive structures, smart structures, composite structures, bio-inspired structures, shell structures, membranes, space structures, lightweight structures, long-span structures, tall buildings, wind turbines, etc); (v) design in traditional engineering materials (steel, concrete, steel-concrete composite, aluminium, masonry, timber, glass); (vi) the process of structural engineering (conceptualisation, planning, analysis, design, optimization, construction, assembly, manufacture, testing, maintenance, monitoring, assessment, repair, strengthening, retrofitting, decommissioning). The SEMC 2019 Proceedings will be of interest to civil, structural, mechanical, marine and aerospace engineers. Researchers, developers, practitioners and academics in these disciplines will find them useful. Two versions of the papers are available. Short versions, intended to be concise but self-contained summaries of the full papers, are in this printed book. The full versions of the papers are in the e-book.
Download or read book Assessment of LTPP Friction Data written by Leslie Titus-Glover and published by . This book was released on 1999 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: "A major goal of the Long-Term Pavement Performance (LTPP) study is the development of recommendations for improving the design and construction of new and rehabilitated pavements to make them longer lasting. As part of the condition monitoring of the LTPP test sections, friction data are being collected on a regular basis at each test site. Friction data collection is the responsibility of the specific highway agency under whose jurisdiction the pavements are located. - The LTPP data collection guidelines for friction data recommend using the ASTM E-274 (AASHTO T242) procedure as the preferred method for obtaining data. The ASTM E-274 procedure uses a locked-wheel skid tester In a trailer assembly. Friction test results are reported as Skid Numbers (SN's). 15. Supplementary Notes This report provides an assessment of the availability, characteristics, and quality of the friction data collected as part of the LTPP study. Also, the availability of related pavement characteristics data was assessed. The report also contains recommendations for adjustments and refinements to current procedures for the collection of friction and related data. The LTPP database provides a one-stop source of reasonably good friction data collected in a systemic manner from a wide range of pavements subjected to a wide range of traffic loading and environmental conditions. The friction data will be of use for analyzing why some pavement surfaces retain good friction characteristics with time and why some surfaces show rapid deterioration in friction over time"--Technical report documentation page.
Download or read book Engineered Cementitious Composites for Electrified Roadway in Megacities written by Ali Aryo Bawono and published by Springer Nature. This book was released on 2022-01-03 with total page 279 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the development of an innovative solution for electrified roadway pavements based on engineered cementitious composites, which are exhibiting an extreme tensile strain capacity that is much higher than conventional concrete. This enables the pavement to work without steel reinforcement and to embed a dynamic wireless power transfer technology for charging electric vehicles. At first, the book presents a modified performance-driven design approach to improve the composites to achieve the optimum pavement design in terms of functional and structural performance. It shows that the modified composites can be used to fulfil the safety and comfort factors without neglecting the characteristics of conventional ones. Further, 3D finite element and fluid dynamics models are used to analyse the pavement properties. The validated models can predict the functional performance, including skid resistance, surface water drainage, and noise. In the remaining part of the thesis, an environmentally-friendly photocatalytic function for pavement made of engineered cementitious composites is investigated. In turn, a multi-criteria design analysis is proposed to identify the optimum functional performance of the pavements. All in all, this book reports on a comprehensive approach to design, analyse and optimize engineered cementitious composites for electrified road pavement application. A special emphasis is given on applications in Singapore and other tropical megacities.

This book was released on 2008 with total page 274 pages. Available in PDF, EPUB and Kindle. Book excerpt: The overall objectives of this research study may be stated as follows: Determine if surface characteristic measurements can be correlated to wet-pavement crashes in Ohio; Provide improved guidance on the use of ribbed versus smooth tires for pavement surface friction testing in Ohio, including the identification of suggested minimum surface friction numbers associated with each tire type; Provide recommended desirable or target surface friction numbers as a function of site categories and friction demand. Accomplishments of these objectives will help ODOT address their goal of reducing total crashes 10 percent and rear-end crashes by 25 percent by 2015.

This book was released on 2000 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: This synthesis report will be of interest to pavement design, construction, management, and research engineers, highway safety officials, and others concerned with pavement friction characteristics. It describes the current state of the practice and discusses the methods used for evaluating wet pavement friction characteristics of new and restored pavements. This synthesis reviews models used for measuring and evaluating friction and texture, causes for friction changes over time, and aggregate and mix design to provide adequate friction. Also presented are construction and surface restoration practices for providing good pavement surface characteristics. In addition, considerations of noise and ride quality are discussed when compromise may be required.

This book was released on 1992 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: This synthesis will be of interest to construction, maintenance, pavement design, and materials engineers, pavement contractors, and others interested in the use of open-graded friction courses (OGFC) as an asphalt concrete pavement wearing surface. Information is provided on performance benefits and limitations of OGFC, material and mixture properties, and current construction practices in use in the United States and Europe. Advances in mixture design and construction techniques have overcome several of the performance limitations identified in early applications of OGFC, as well as enhanced the performance benefits associated with OGFC use. This report of the Transportation Research Board describes the current state of the practice with respect to the use of OGFC. Experience with the design, construction, and performance of OGFC is summarized, based on a review of the literature, documentation of experience from applications in the U.S. and Europe, and site visits to several states.
