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

Waste polymers have been studied for various applications such as energy generation and biochemical production; however, their application in asphalt roads still poses some questions. Over the last decade, several studies have reported the utilization of waste plastics in roads using different methodologies and raw materials, but there is still significant inconsistency around this topic. What is the right methodology to recycle waste plastics for road applications? What is the correct type of waste plastics to be used in road applications? What environmental concerns could arise from the use of waste plastics in road applications? Plastic Waste for Sustainable Asphalt Roads covers the various processes and techniques for the utilization of waste plastics in asphalt mixes. The book discusses the various material properties and methodologies, effects of various methodologies, and combination of various polymers. It also provides information on the compatibility between bitumen and plastics, final asphalt performance, and environmental challenges. - Discusses the processes and techniques for utilization of waste plastics in asphalt mixes. - Features a life-cycle assessment of waste plastics in road surfaces and possible Environmental Product Declarations (EPD). - Includes examples of on-field usage through various case studies.

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.

The civil engineering sector accounts for a significant percentage of global material and energy consumption and is a major contributor of waste material. The ability to recycle and reuse concrete and demolition waste is critical to reducing environmental impacts in meeting national, regional and global environmental targets. Handbook of recycled concrete and demolition waste summarises key recent research in achieving these goals.Part one considers techniques for managing construction and demolition waste, including waste management plans, ways of estimating levels of waste, the types and optimal location of waste recycling plants and the economics of managing construction and demolition waste. Part two reviews key steps in handling construction and demolition waste. It begins with a comparison between conventional demolition and construction techniques before going on to discuss the preparation, refinement and quality control of concrete aggregates produced from waste. It concludes by assessing the mechanical properties, strength and durability of concrete made using recycled aggregates. Part three includes examples of the use of recycled aggregates in applications such as roads, pavements, high-performance concrete and alkali-activated or geopolymer cements. Finally, the book discusses environmental and safety issues such as the removal of gypsum, asbestos and alkali-silica reaction (ASR) concrete, as well as life-cycle analysis of concrete with recycled aggregates.Handbook of recycled concrete and demolition waste is a standard reference for all those involved in the civil engineering sector, as well as academic researchers in the field. - Summarises key recent research in recycling and reusing concrete and demolition waste to reduce environmental impacts and meet national, regional and global environmental targets - Considers techniques for managing construction and demolition waste, including waste management plans, ways of estimating levels of waste, the types and optimal location of waste recycling plants - Reviews key steps in handling construction and demolition waste
