Highways provide the arteries of modern society. The interaction of road, rail and other transport infrastructure with the ground is unusually intimate, and thus needs to be well-understood to provide economic and reliable infrastructure for society. Challenges include not only the design of new infrastructure (often on problematic ground), but increasingly the management and maintenance of aging assets in the face of issues such as climate change. This book is the written record of the first International Conference on Transportation Geotechnics held under the auspices of the International Society of Soil Mechanics and Geotechnical Engineering, held in Nottingham, UK, in 2008. It comprises about 100 papers from a global selection of researchers and practitioners on: – Slope instability, stabilisation, and asset management; – Construction on soft ground; – Interaction with structures and geogrid reinforced soil; – Effect of climate change and vegetation; – Highways, pavements and subgrade; – Railway geotechnics; – Soil improvement; – Characterisation and recycling of geomaterials. A further part of this collection contains papers on unbound aggregate materials as used in pavement construction and drainage. They formed the ‘Unbound Aggregates in Roads (UNBAR7)’ theme of the conference which followed on from the previous symposia of that title, also held in Nottingham, UK, most recently in 2004. The volume will be of interest to professionals and academics in geotechnical, highway, railway and general civil engineering.

This comprehensive design guide summarizes current developments in the design of concrete pavements. Following an overview of the theory involved, the authors detail optimum design techniques and best practice, with a focus on highway and infrastructure projects. Worked examples and calculations are provided to describe standard design methods, illustrated with numerous case studies. The author provides guidance on how to use each method on particular projects, with reference to UK, European and US standards and codes of practice. Concrete Pavement Design Guidance Notes is an essential handbook for civil engineers, consultants and contractors involved in the design and construction of concrete pavements, and will also be of interest to students of pavement design.

This is a book about the history of both language and culture. By the application of logic (and a little simple maths) Nick Thom is able to demonstrate that the history today's languages can be traced back in time and space over many thousands of years, throwing light on issues such as the root of Basque speech, the origins of Chinese culture, even the peopling of the Americas. The story which unfolds is one of fascinating twists and turns, of massive waves of 'culture' sweeping all before them, and of remarkable survival against the odds.

The disturbed state concept (DSC) is a unified, constitutive modelling approach for engineering materials that allows for elastic, plastic, and creep strains, microcracking and fracturing, stiffening or healing, all within a single, hierarchical framework. Its capabilities go well beyond other available material models yet lead to significant simplifications for practical applications. Until now, however, there has been no resource that fully describes the theory, techniques, and potential of this powerful method. Mechanics of Materials and Interfaces: Disturbed State Concept presents a detailed theoretical treatment of the DSC and shows that it can provide a unified and simplified approach for mathematical characterization of the mechanical response of materials and interfaces. Within this comprehensive treatment, the author: Compares the DSC with other available models Identifies the physical meaning of the relevant parameters and presents procedures to determine them from laboratory test data Validates the DSC models with respect to laboratory tests used to find the parameters and independent tests not used in the calibration Implements the models in computer procedures Validates those procedures by comparing predictions with observations from simulated and field boundary value problems Solves problems from a variety of disciplines, including civil, mechanical, and electrical engineering If you are involved in the mechanics of materials, you owe it to yourself to explore the disturbed state concept. Mechanics of Materials and Interfaces provides the first-and to date, the only-comprehensive means of doing so.

Forming the 23rd addition to a successful series, this book contains papers presented by an extensive selection of international delegates at the 23rd International Conference on Urban Transport and the Environment. Due to its continued success and multiplicity of topics, the series is considered to be a leading source of new research in the area of transport engineering. Transportation in urban areas, with its related environmental and social impacts, is of significant concern for government policymakers and for the urban citizens who need efficient transport systems. Extensive reviews of these systems are required to devise and then safeguard their operational use, maintenance, safety and security. The continuing requirement for better and more efficient urban transport systems and the need for a healthier environment has added to the increasing international desire for new technologies and developments in this essential field. The variety of topics covered reflects the complex interaction of urban transport systems with their environment and the need to establish integrated strategies. These topics include: Public transport systems; Urban transport planning and management; Environmental impact; Economic and social impact; Safety and security; Transportation modelling and simulation; Intelligent and advanced transport systems; City logistics; Inter-modal transport systems; Mass transport strategies; Freight transport; Railway systems; Port and city; Mobility and public space; Innovative electric transportation; Eco-mobility transport systems; Integrated network systems; Traditional and alternative fuels and energy; Public policies and governance.

The book tackles a number of challenging questions: How can we conceptualize architectural objects and practices without falling into the divides architecture/society, nature/culture, materiality/meaning? How can we prevent these abstractions from continuing to blind architectural theory? What is the alternative to critical architecture? Mapping controversies is a research method and teaching philosophy that allows divides to be crossed. It offers a new methodology for following debates surrounding contested urban knowledge. Engaging in explorations of on-going and recent controversies and re-visiting some well-known debates, the analysis foregrounds, traces and maps the changing sets of positions triggered by design: the 2012 Olympics stadium in London, the Welsh parliament in Cardiff, the Heathrow airport runway extension, the Sydney Opera House, the Eiffel Tower. By mobilizing digital technologies and new computational design techniques we are able to visualize the variety of factors that impinge on design and track actors' trajectories, changing groupings, concerns and modalities of action. The book places architecture at the intersection of the human and the nonhuman, the particular and the general. It allows its networks to be re-established and to run between local and global, social and technical. Mapping controversies can be extrapolated to a wide range of complex phenomena of hybrid nature.
