Download or read book Recycled Materials and by Products in Highway Applications written by Mary Stroup-Gardiner and published by Transportation Research Board. This book was released on 2013 with total page 103 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recycled materials and industrial byproducts are being used in transportation applications with increasing frequency. There is a growing body of experience showing that these materials work well in highway applications. This study gathers the experiences of transportation agencies in determining the relevant properties of recycled materials and industrial byproducts and the beneficial use for highway applications. Information for this study was acquired through a literature review, and surveys and interviews with state department of transportation staff. The report will serve as a guide to states revising the provisions of their materials specifications to incorporate the use of recycled materials and industrial byproducts, and should, thereby, assist producers and users in leveling the playing field for a wide range of dissimilar materials.

Available in PDF, EPUB and Kindle. Book excerpt: In 1991, the U.S. Congress passed the Intermodal Surface Transportation Efficiency Act, or ISTEA as it is commonly refered to . Section 1038 of the ISTEA, required the Secretary of Trnasportation and the Administrator of the U.S. Environmental Protection Agency (EPA) to jointly conduct studies to determine the economic savings, technical performance qualities, threats to human health and the environment, and the environmental benefits of using recycled material in highway devices and appurtenances, as well as highway projects. A wide variety of waste materials have been or could be appropriate for use as a highway construction material. A symposium held in October of 1993 presented informationon the wide variety of worldwide research that is now underway in the area of recycling. Based on the results of that symposium, this paper provides information on some more promising and innovative uses for what would other wise be considered waste material. Materials covered in this paper include: Blast furnace and steel slags; Carpet fibers; Coal-ash by-products including fly ash, botton ash and flue gas desulfurization waste; Glass; Municipal solid waste combustion ash; Recycled plastic; Roofing shingle wastes; and Rubber tires for uses other than in asphalt pavements. Each material is birefly described and some of the current research projects using these materials are presented. Information regarding performance is also presented, as available. Material availability, environmental concerns, and disposal problesm are also briefly described. For the covering abstract of this conference, see IRRD number 863140.

This book was released on 1998 with total page 154 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over 4.5 billion tons of non-hazardous wastes are generated in the United States each year. Out of these wastes over 200 million tons of post consumer waste is generated. The disposal of post consumer waste is the responsibility of municipality and society. Four waste materials, glass, plastic, rubber tires and paper and paperboard, were selected for detailed study. A questionnaire survey was conducted for obtaining input from all state departments of transportation (DOTs) and recyclers and solid waste management facilities in the state of Ohio. Responses received from state DOTs stated that they use various recycled materials in highway construction but do not conduct cost-effectiveness analysis of recycled waste materials. The cost of disposal of post consumer waste is increasing, which requires an alternate use for these waste materials. One possible use of these post consumer waste materials is in highway construction. An economic analysis is needed for their cost-effectiveness determination before using these materials in highway construction. Though these recycled waste materials are expensive compared to virgin material, consideration of the savings in terms of societal cost makes these materials become cost-effective and attractive to use in highway construction. Concepts of marginal costs and marginal benefits are used in developing the cost-effective analysis of recycled materials. The recycled waste material will be competitive with the new material if costs such as disamenity costs of disposal and landfill costs are added to the material costs. Benefits from recycling are numerous, such as the revenue generated from recycling and sale of material, avoidance of disposal costs, and improvement in environmental quality. Revenue from sale of each material is treated as a reduction in costs. Combining all costs together provides a platform to develop a marginal benefit function for recycling. A computer program was developed using Microsoft Access (trademark) to provide a tool in making an economic decision.

This book was released on 2022-02-28 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book considers the application of recycled materials both in pavement and geotechnical engineering. Currently, Australia has faced the fundamental concern of recycling waste plastic. On 1 January 2018, China enforced a prohibition on the importation of waste plastic. China's ban is followed by other countries like India, Indonesia, and Malaysia. The ban caused many corporations to abandon waste collection agreements, and the stockpiling of waste, as there is nowhere to safely deposit this waste. This issue seems, to a great extent, to have placed Australia's recycling industry in a crisis. As a result, local councils will have to find strategic ways of recycling accumulated waste that will become a more significant issue in the coming years. In Australia, apart from economic growth, the road pavement has weakened rapidly as the current pavement unable to withstand this urgent traffic load demand. The adding of polymers to the mixtures improves the stiffness, rutting resistance, and fatigue cracking [1]. However, the application of virgin polymer is costly. Thus, using waste polymer such as waste plastic polymer is an inexpensive substitute. The potential for recycled plastic to improve the performance properties of asphalt mixtures has been demonstrated in many countries the UK, Canada, The Netherlands, and India [2]. Similarly, another application of recycled materials can be in geotechnical infrastructure. This book considers the application of recycled materials both in pavement and geotechnical engineering.

Download or read book Uses of Recycled Rubber Tires in Highways written by Jon A. Epps and published by Transportation Research Board. This book was released on 1994 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: This synthesis on the use of recycled rubber tires in highways will be of interest to administrators and policy-makers; pavement, materials, geotechnical, environmental, and traffic operations engineers; and research engineers involved with highway design and construction issues. Information is provided on the uses of rubber tires in asphalt paving materials as well as other uses, such as on fills and embankments, for erosion control and on railroad grade crossings. Specifically, information is included which identifies the agencies using or implementing applications for recycled rubber tires and defines the design parameters, technical and construction limitations, performance, costs, benefits, environmental limitations, specifications, and availability. This synthesis of information defines the use of recycled rubber tires in highways and is based on a review of nearly 500 references and on information recorded from state highway agency responses to a 1991 survey of practice. Updates are included for as much of the state practice information possible through 1993. The use of scrap tires for highway applications is dynamic with regard to policy and technical issues. Therefore, the reader should keep in mind that the information presented reflects the best available data at a particular time. The synthesis also identifies current research in the topic area, critical research needs, and legislative issues that affect application and use of recycled rubber tires.
