Trials of High-friction Surfaces for Highways
Author: J.C. NichollsPublisher: Thomas Telford
ISBN: 9780727728050
Category : Pavements
Languages : en
Pages : 32
Book Description
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.
Asphalt Surfacings
Author: J Cliff NichollsPublisher: CRC Press
ISBN: 9780419231103
Category : Architecture
Languages : en
Pages : 662
Book Description
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.

Engineered Cementitious Composites for Electrified Roadway in Megacities
Author: Ali Aryo BawonoPublisher: Springer Nature
ISBN: 3030885429
Category : Technology & Engineering
Languages : en
Pages : 279
Book Description
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.
