Download or read book Trials of High friction Surfaces for Highways written by J.C. Nicholls and published by Thomas Telford. This book was released on 1998 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: High-friction surface systems are used to support the DETR`s skidding standard on high stress sites. Until recently an epoxy resin was used as a binder to obtain the necessary skid resistance, but with increased demand for high-friction surface systems, alternative systems have come onto the market using different resins as binders. This report describes a series of road trials, set up to compare the performance of a range of resin systems (epoxy-resin, polyurethane-resin, acrylic-resin and rosin-ester). Systems are ranked in terms of maintained skid resistance, texture depth and longevity. Consideration of the different laying techniques employed for different resins indicates that the choice of resin type may be influenced by constraints imposed while laying as well as the performance requirements in service. The results from a series of laboratory tests which have been devised to simulate accelerated wear under trafficking support the road trial conclusions. The results have been used to develop performance-related criteria for a Highway Authorities Product Approval Scheme (HAPAS) certification procedure which can be used to assess existing systems and systems that may be developed in future.

Download or read book 8th RILEM International Conference on Mechanisms of Cracking and Debonding in Pavements written by Armelle Chabot and published by Springer. This book was released on 2016-05-25 with total page 735 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the latest advances in research to analyze mechanical damage and its detection in multilayer systems. The contents are linked to the Rilem TC241 - MCD scientific activities and the proceedings of the 8th RILEM International Conference on Mechanisms of Cracking and Debonding in Pavements (MCD2016). MCD2016 was hosted by Ifsttar and took place in Nantes, France, on June 7-9, 2016. In their lifetime, pavements undergo degradation due to different mechanisms of which cracking is among the most important ones. The damage and the fracture behavior of all its material layers as well as interfaces must be understood. In that field, the research activities aims to develop a deeper fundamental understanding of the mechanisms responsible for cracking and debonding in asphalt concrete and composite (e.g. asphalt overlays placed on PCC or thin cement concrete overlay placed on asphalt layer) pavement systems.

Download or read book Asphalt Surfacings written by J Cliff Nicholls and published by CRC Press. This book was released on 2002-11-01 with total page 425 pages. Available in PDF, EPUB and Kindle. Book excerpt: Asphalt Surfacings has been written as a reference to the various asphalt course materials and surfacing treatments that are currently available to engineers, enabling them to select the materials and/or treatment that are appropriate for use on specific sites. Appropriate reference is made to the lower structural layers as the properties of all layers interact in producing the required pavement. The current established position in the UK and the emerging developments throughout the UK and Europe are covered. The contributors are all acknowledged authorities on their particular topics selected from every part of the highway engineering industry to achieve a balance between the various approaches required by the different functions they perform.

Download or read book International Encyclopedia of Transportation written by and published by Elsevier. This book was released on 2021-05-13 with total page 4418 pages. Available in PDF, EPUB and Kindle. Book excerpt: In an increasingly globalised world, despite reductions in costs and time, transportation has become even more important as a facilitator of economic and human interaction; this is reflected in technical advances in transportation systems, increasing interest in how transportation interacts with society and the need to provide novel approaches to understanding its impacts. This has become particularly acute with the impact that Covid-19 has had on transportation across the world, at local, national and international levels. Encyclopedia of Transportation, Seven Volume Set - containing almost 600 articles - brings a cross-cutting and integrated approach to all aspects of transportation from a variety of interdisciplinary fields including engineering, operations research, economics, geography and sociology in order to understand the changes taking place. Emphasising the interaction between these different aspects of research, it offers new solutions to modern-day problems related to transportation. Each of its nine sections is based around familiar themes, but brings together the views of experts from different disciplinary perspectives. Each section is edited by a subject expert who has commissioned articles from a range of authors representing different disciplines, different parts of the world and different social perspectives. The nine sections are structured around the following themes: Transport Modes; Freight Transport and Logistics; Transport Safety and Security; Transport Economics; Traffic Management; Transport Modelling and Data Management; Transport Policy and Planning; Transport Psychology; Sustainability and Health Issues in Transportation. Some articles provide a technical introduction to a topic whilst others provide a bridge between topics or a more future-oriented view of new research areas or challenges. The end result is a reference work that offers researchers and practitioners new approaches, new ways of thinking and novel solutions to problems. All-encompassing and expertly authored, this outstanding reference work will be essential reading for all students and researchers interested in transportation and its global impact in what is a very uncertain world. Provides a forward looking and integrated approach to transportation Updated with future technological impacts, such as self-driving vehicles, cyber-physical systems and big data analytics Includes comprehensive coverage Presents a worldwide approach, including sets of comparative studies and applications
