Alternative Materials in Road Construction


Book Description

With the landfill tax and the introduction of a tax on the use of primary aggregates, increasing financial pressure is now being exerted on highway engineers to provide the most economic alternatives to naturally-occurring roadmaking materials. Alternative materials in road construction: Second edition, provides practical guidance in the selection of substitute materials, including the economic and technical considerations of their use and advice on the benefits and pitfalls of each material. This fully revised second edition includes: Extensively re-written and updated sections on classification and sources Specifications of road making materials and environmental and economic considerations Enlarged sections on construction and demolition wastes to take account of the increasing concern at the depletion of natural resources and the much greater emphasis on recycling A new chapter on Government and EC Policy with respect to environmental damage and recycling Alternative materials in road construction: Second edition is divided into three parts. Part 1 discusses the demand and requirements of road making materials and the specifications that they have to meet if they are to give sa




Alternative Materials in Road Construction


Book Description

This text considers the extent to which waste materials and industrial by-products can be used in road construction projects in place of the natural materials traditionally used. It brings together a listing of all the available waste material products, and explores their potential as both technical and economical alternatives to natural materials.




Sustainability and Automation in Smart Constructions


Book Description

This book gathers outstanding papers presented at the Conference on Automation Innovation in Construction (CIAC-2019). In recent years, there have been significant transformations in the construction sector regarding production and the use of computers and automation to create smart and autonomous systems. At the same time, innovative construction materials and alternative technologies are crucial to overcoming the challenges currently facing the building materials industry. The book presents numerous examples of smart construction technologies, discusses the applications of new construction materials and technologies, and includes studies on recent trends in automation as applied to the construction sector.




Waste and Byproducts in Cement-Based Materials


Book Description

Waste and By-Products in Cement-Based Materials: Innovative Sustainable Materials for a Circular Economy covers various recycled materials, by-products and wastes that are suitable for the manufacture of materials within the spectrum of so-called cement-based materials (CBM). Sections cover wastes for replacement of aggregates in CBM, focus on the application of wastes for the replacement of clinker and mineral additions in the manufacture of binders, discuss the optimization process surrounding the manufacture of recycled concrete and mortars, multi-recycling, advanced radiological studies, optimization of self-compacting concrete, rheology properties, corrosion prevention, and more. Final sections includes a review of real-scale applications that have been made in recent years of cement-based materials in roads, railway superstructures, buildings and civil works, among others, as well as a proposal of new regulations to promote the use of waste in the manufacture of CBM. - Favors the institution of the circular economy in the construction industry by eliminating the barriers that currently prevent industrial waste from being valorized by its inclusion in CBM design - Features an in-depth exploration of the strengths and weaknesses of new raw materials and their application to CBMs - Features real-scale applications that have been made in recent years of cement-based materials in roads, railway superstructures, buildings and civil works, among others - Presents current, state-of-the-art, and future-prospects for the use of industrial waste in CBMs




Gravel Roads


Book Description

The purpose of this manual is to provide clear and helpful information for maintaining gravel roads. Very little technical help is available to small agencies that are responsible for managing these roads. Gravel road maintenance has traditionally been "more of an art than a science" and very few formal standards exist. This manual contains guidelines to help answer the questions that arise concerning gravel road maintenance such as: What is enough surface crown? What is too much? What causes corrugation? The information is as nontechnical as possible without sacrificing clear guidelines and instructions on how to do the job right.




Unbound Aggregates in Roads


Book Description

Unbound Aggregates in Roads contains the proceedings of the International Symposium on Unbound Aggregates in Roads (UNBAR3) held at the University of Nottingham, England, on April 11-13, 1989. The papers focus on unbound aggregates used in road construction and cover topics ranging from drainage and permeability to placement and compaction of unbound aggregates, design philosophy, specification, and compliance. This book consists of 49 chapters divided into eight sections and opens with an overview of the functions of unbound aggregates in roads, followed by a discussion on the mechanical properties of different aggregates and theoretical aspects of granular materials. The following chapters focus on granular drainage layers in pavement foundations; residual stresses caused by compaction in granular materials; and alternative materials for road construction such as steel slags and natural and waste materials. The use of unbound road aggregates in various countries such as Italy, France, Germany, and Portugal is also considered. This monograph will be a useful resource for designers, aggregate producers, contractors, specification writers, and materials engineers.







Handbook of Research on Advancements in Environmental Engineering


Book Description

The protection of clean water, air, and land for the habitation of humans and other organisms has become a pressing concern amid the intensification of industrial activities and the rapidly growing world population. The integration of environmental science with engineering principles has been introduced as a means of long-term sustainable development. The Handbook of Research on Advancements in Environmental Engineering creates awareness of the role engineering plays in protecting and improving the natural environment. Providing the latest empirical research findings, this book is an essential reference source for executives, educators, and other experts who seek to improve their project's environmental costs.




Civil and Environmental Engineering: Concepts, Methodologies, Tools, and Applications


Book Description

Civil and environmental engineers work together to develop, build, and maintain the man-made and natural environments that make up the infrastructures and ecosystems in which we live and thrive.
