Proceedings of the RILEM International Symposium on Bituminous Materials


Book Description

This volume highlights the latest advances, innovations, and applications in bituminous materials and structures and asphalt pavement technology, as presented by leading international researchers and engineers at the RILEM International Symposium on Bituminous Materials (ISBM), held in Lyon, France on December 14-16, 2020. The symposium represents a joint effort of three RILEM Technical Committees from Cluster F: 264-RAP “Asphalt Pavement Recycling”, 272-PIM “Phase and Interphase Behaviour of Bituminous Materials”, and 278-CHA “Crack-Healing of Asphalt Pavement Materials”. It covers a diverse range of topics concerning bituminous materials (bitumen, mastics, mixtures) and road, railway and airport pavement structures, including: recycling, phase and interphase behaviour, cracking and healing, modification and innovative materials, durability and environmental aspects, testing and modelling, multi-scale properties, surface characteristics, structure performance, modelling and design, non-destructive testing, back-analysis, and Life Cycle Assessment. The contributions, which were selected by means of a rigorous international peer-review process, present a wealth of exciting ideas that will open novel research directions and foster new multidisciplinary collaborations.




Progress of Superpave (superior Performing Asphalt Pavement)


Book Description

A major result of the research conducted under the Strategic Highway Research Program from 1987 to 1993 was the development of the Superpave (Superior Performing Asphalt Pavement) system for the comprehensive design of asphalt pavements. These 14 contributions describe the experience to date in the




Summary Report on Aging of Asphalt-aggregate Systems


Book Description

This is a report on the state of the art of research on the phenomenon of the aging of asphalt-aggregate mixtures. Compared to research on the aging of asphalt cement, there has been little research on the aging of asphalt mixtures. Binder studies are considered as well as mixture sutdies, the relationship between laboratory aging tests and field performance, and the relationship between chemical composition and field performance. Recommendations are made for aging procedures which show promise for laboratory investigation. Test methods to evaluate aging are also considered. It is noted that extended heating procedures show the most promise for short-term aging and pressure oxidation and/or extended heating the most promise for long-term aging.




Short-term Laboratory Conditioning of Asphalt Mixtures


Book Description

This report develops procedures and associated criteria for laboratory conditioning of asphalt mixtures to simulate short-term aging. The report presents proposed changes to the American Association of State Highway and Transportation Officials (AASHTO) R 30, Mixture Conditioning of Hot-Mix Asphalt (HMA), and a proposed AASHTO practice for conducting plant aging studies. The report will be of immediate interest to materials engineers in state highway agencies and the construction industry with responsibility for design and production of hot and warm mix asphalt.




Urban Transport XIV


Book Description

Transportation in cities, with its related environmental and social concerns continues to be a topic of the utmost priority for urban authorities and central governments around the world. Frequently, the concern is not orderly but driven by the safety crises, which take place regularly, and even the best-planned urban transport systems require considerable studies to safeguard their safety, maintenance and operational use. On a broader front, the continuing need for better urban transport systems in general and the need for a healthier environment has led to an increased level of research around the world. This is reflected in the proceedings of the Thirteenth International Conference on Urban Transport and the Environment in the 21st Century, which stresses the continuous steady growth and research into the urban transport systems control aspects, information and imulation systems. All these topics continue to be of importance for analyzing the complex inter-relation of the urban transport environment and for establishing action strategies for transport and traffic problems. Of interest to engineers, scientists and managers working in industry, universities, research organizations and government involved in the planning and management of urban transportation systems and transport policy, this book contains papers within the following subject areas: Environmental and ecological considerations; Information systems and GPS applications; Intelligent transport systems; Intermodel passenger transport systems; Land use and transport integration; Modality in freight; Public transport systems; Road pricing; Traffic management; Transport automation; Transport logistics and operations research; Transport modelling and simulation; Transport security and safety; Transport sustainability; Transport technology; Urban transport planning.

Highway Research


Book Description

The level of research activity in the highway sector as a whole has declined precipitously in recent decades, whilst the challenges facing US state highway agencies have escalated. As a result, a Strategic Highway Research Program - SHRP) was initiated to establish collaboration with research bodies tackling similar highway problems in countries worldwide. This collection of reports from around the world presents SHRP`s progress towards providing research-based new products from which the international highway engineering community may benefit. SHRP concentrates on six high-priority research areas: asphaltic materials; pavement performance; cement and concrete; maintenance cost effectiveness; concrete bridge component protection systems and the chemical control of snow and ice.
