Nearly all highway, airport, dock and industrial pavements contain large quantities of untreated aggregate in the form of unbound pavement layers. In many pavements, which are lightly or moderately trafficked, crushed rock or gravel derived aggregates comprise the majority of the construction or, in the case of unsealed pavements, all of the structure. This book provides studies of the performance and description of this material that will help the reader to better understand its characteristics and behaviour both alone and as part of the pavement structure it forms. This work will be useful to practitioners, policy makers, researchers and students. It forms a sequel to the earlier book "Unbound Aggregates in Road Construction" also published by Balkema

Developing countries in the tropics often have challenging natural conditions and different institutional and financial institutions to industrialized countries. However, most textbooks on road engineering are based on experience in industrialized countries with temperate climates.

Road Engineering for Development (published as Highway and Traffic Engineering in Developing Countries in its first edition) provides a comprehensive coverage of the planning, design, construction and maintenance of roads in developing and emerging countries. It covers a wide range of technical and non-technical problems that may confront road engineers working in the developing world. This new edition has extended the focus to include those countries of the former Eastern Bloc, which share many institutional issues and the financial problems confronting developing countries.

Designed as a fundamental text for civil engineering students this book also offers a broad, practical view of the subject for practising engineers. It has been written with the assistance of a number of world-renowned specialist professional engineers with many years experience working in Africa, the Middle East, Asia and Central America.

This book comprises the proceedings of the Annual Conference of the Canadian Society of Civil Engineering 2021. The contents of this volume focus on specialty conferences in construction, environmental, hydrotechnical, materials, structures, transportation engineering, etc. This volume will prove a valuable resource for those in academia and industry.

This book provides an overview of asphalt pavement maintenance, highlighting the key asphalt pavement maintenance technologies in China. It analyzes the trend toward preventive maintenance technologies and proposes technical guidelines and implementation rules for preventive maintenance.

Road traffic and its impacts affect all aspects of modern life, leisure and industry, with safety, congestion and pollution being of greatest public concern. Transport planning increasingly emphasises travel demand management (TDM) and traffic calming - aided by dynamic, lower cost data from Intelligent Transport Systems (ITS) - to enable real time monitoring, control and traveller information. This second edition of a highly successful work has been fully updated since its first publication in 1996 to reflect developments in technology available to the traffic analyst and in the social, ecological and economic environment. New sections are included on shockwaves, data capture without surveys, traffic incidents, delay estimation, off-line use of on-line data, environmental sensitivity, and controlled crash tests. The authors introduce and demonstrate techniques with which the analyst, engineer or planner can examine traffic problems. The underlying theme is that proper understanding of traffic systems performance and traffic problems can only come from the intelligent processing, refinement, appraisal and evaluation of traffic data. Arranged in five parts, the book offers an integrated approach to tackling road traffic problems: c How to gain information and understanding about traffic c The theories of traffic flow c The principles of good survey planning and management c Specific types of traffic studies c Analytical techniques for transforming raw data into useful information. Understanding Traffic Systems provides cogent insights into the techniques of traffic data collection and analysis, the application of traffic theory and the role of data in analysis and decision making. Its breadth and use of examples from several countries make it a useful reference text for students and researchers, as well as an essential tool for practising traffic engineers and planners.

This interdisciplinary volume comprises papers from several fields related to compaction. Topics include: soil compaction for pavements and roads; deep soil compaction by vibration, impact and underground explosion; compaction control; and compaction processes in engineering.

Highway engineers are facing the challenge not only to design and construct sustainable and safe pavements properly and economically. This implies a thorough understanding of materials behaviour, their appropriate use in the continuously changing environment, and implementation of constantly improved technologies and methodologies. Bituminous Mixtures and Pavements VII contains more than 100 contributions that were presented at the 7th International Conference 'Bituminous Mixtures and Pavements' (7ICONFBMP, Thessaloniki, Greece 12-14 June 2019). The papers cover a wide range of topics: - Bituminous binders - Aggregates, unbound layers and subgrade - Bituminous mixtures (Hot, Warm and Cold) - Pavements (Design, Construction, Maintenance, Sustainability, Energy and environment consideration) - Pavement management - Pavement recycling - Geosynthetics - Pavement assessment, surface characteristics and safety - Posters Bituminous Mixtures and Pavements VII reflects recent advances in highway materials technology and pavement engineering, and will be of interest to academics and professionals interested or involved in these areas.

At first glance, roads seem like the simplest possible geotechnical structures. However, analysis of these structures runs up against complexities related to the intense stresses experienced by road surfaces, their intense interaction with climate, and the complicated behavior of the materials used in road construction. Modern mechanistic approaches to road design provide the tools capable of developing new technical solutions. However, use of these approaches requires deep understanding of the behavior of constituent materials and their interaction with water and heat which has recently been acquired thanks to advances in geotechnical engineering. The author comprehensively describes and explains these advances and their use in road engineering in the two-volume set Geotechnics of Roads, compiling information that had hitherto only been available in numerous research papers. Geotechnics of Roads: Fundamentals presents stresses and strains in road structures, water and heat migration within and between layers of road materials, and the effects of water on the strength and stiffness of those materials. It includes a deep analysis of soil compaction, one of the most important issues in road construction. Compaction accounts for only a small proportion of a construction budget but its effects on the long-term performance of a road are decisive. In addition, the book describes methodologies for nondestructive road evaluation including analysis of continuous compaction control, a powerful technique for real-time quality control of road structures. This unique book will be of value to civil, structural and geotechnical engineers worldwide.

This volume provides an overview of the proceedings of the XIIth ECSME Conference 1999. It covers a wide variety of topics, from summaries of workshops and sessions, to the emergence of information technology and information retrieval and communication.

This interdisciplinary volume comprises papers from several fields related to compaction. Topics include: soil compaction for pavements and roads; deep soil compaction by vibration, impact and underground explosion; compaction control; and compaction processes in engineering.

The aim of the studies presented in this report is the implementation of rational concepts and testing procedures for the design and manufacture of bituminous materials for applications in pavement construction. Practical test procedures are recommended for binder evaluation, mix design and performance assessment of bituminous materials. The three main topics addressed are binder testing, mix design and mechanical testing of mixtures. Each is examined through inter-laboratory tests and there is a literary review of existing practices and methods for the production of polymer-modified binders, mixture design and the mechanical properties of mixtures.

This book covers the basic scientific theory and related application technologies of the pantograph-catenary system, including research findings on pantograph/catenary contact resistance, pantograph interface thermal effect, laws and characteristics of current-carrying friction and wear, the main research methods for pantograph arcs, the effects of arcs on pantograph systems and onboard equipment, and the materials used for pantographs and contact wires. Given its scope, it offers a valuable resource for students, scholars, and development engineers alike. The relationship between pantograph and catenary is one of the three core aspects of the safe operation of high-speed electrified railways. The pantograph system provides electric power for the high-speed train through the sliding electric contact. As the train's operating speed increases, the pantograph system enters a state of prolonged sliding/vibration, resulting in frequent arcs, electrode erosion, and increased wear.

Incorporating the proceedings of RILEM TC-PRC third conference on this subject, this volume includes papers from road authorities, engineers, researchers, contractors and manufacturers discussing the implementation and the long term behaviour of overlay systems. This book should be of interest to research institutes concerned with transportation and highway engineering; government and local authority engineers, contractors, material suppliers.

This book describes an effective decision-making and planning architecture for enhancing the navigation capabilities of automated vehicles in the presence of non-detailed, open-source maps. The system involves dynamically obtaining road corridors from map information and utilizing a camera-based lane detection system to update and enhance the navigable space in order to address the issues of intrinsic uncertainty and low-fidelity. An efficient and human-like local planner then determines, within a probabilistic framework, a safe motion trajectory, ensuring the continuity of the path curvature and limiting longitudinal and lateral accelerations. LiDAR-based perception is then used to identify the driving scenario, and subsequently re-plan the trajectory, leading in some cases to adjustment of the high-level route to reach the given destination. The method has been validated through extensive theoretical and experimental analyses, which are reported here in detail.

This book presents a rigorous treatment of the fundamental mathematical behaviour of pavement structures under dynamic loading. The subject is of importance in design of economic highway pavements and aircraft runways for increasingly arduous performance requirements. The author and his team have worked for many years on developing dynamic testing methods of road surfaces and materials using vibration techniques with low excitation energy. Their experimental work on test tracks has led to the development and refinement of models of the behaviour of pavement structures, which can be used for practical applications. The book contains many numerical examples of pavement evaluation and design using this approach. The book should be valuable for researchers and graduate students in the field of highway engineering, structural dynamics and soil mechanics, and also for professional highway engineers concerned with dynamic behaviour of pavements.

As a consequence of so much construction work being carried out on or near highways, contractors ignore at their peril the law of highways and the influence it has, or should have, on their working methods and practices. Some knowledge of the law relating to highways is essential to anyone involved in the construction process, including the architect, engineer or surveyor advising a client as to what is possible and the contractor actually carrying out the contract works. By avoiding legal language, this book aims to provide practical guidance from maintenance and improvements to activities related to construction work on or near highways.

This book sets the modern infrastructure of smart devices and services into the perspective of the future smart cities and communities. In the course of this, it discusses the major technological solutions and steps toward integrated logistics solutions to be used in these environments with their benefits in terms of efficiency, interoperability, and sustainability. By doing so, it paves the logistician's way toward the aspired innovation society.

This book offers an overview of sustainability and urban mobility in the context of urban planning - topics that are of considerable interest in the development of smart cities. Environmental sustainability is universally recognized as a fundamental condition for any urban policy or urban management activity, while mobility is essential for the survival of complex urban systems. The new opportunities offered by innovations in the mobility of people, goods and information, as well as radically changing interactions and activities are transforming cities. Including contributions by urban planning scholars, the book provides an up-to-date picture of the latest studies and innovative policies and practices in Italy, of particular interest due to its spatial, functional and social peculiarities. Sustainability and mobility must form the basis of "smart planning" - a new dimension of urban planning linked to two main innovations: procedural innovation in the management of territorial transformations and the technological innovation of the generation, processing and distribution of data (big data) for the creation of new "digital environments" such as GIS, BIM, models of augmented and mixed reality, useful for describing changes in human settlement in real time.

This book explores the geography of the everyday roadway and contemplates how regulation and design shape our streets. People may question the hegemony of cars, but reimagining public streets is a major conceptual and technical challenge. Drawing from "new mobilities" and transport studies, Prytherch addresses how streets are structured by policy standards; what it means to have a right to the street; and how a more just street would look-in both theory and practice. He summarizes key traffic statutes, case laws, and engineering manuals, and interprets these in relation to mobility rights and justice. At its core, the book moves beyond criticism to highlight emerging movements which aim to develop more complete and livable streets for everyone.
