Available in PDF, EPUB and Kindle. Book excerpt: This research project covered a wide range of activities that allowed researchers to understand the relationship between stability, pavement distress, and recycled portland cement concrete (RPCC) subbase aggregate materials. Detailed laboratory and field tests, including pavement distress surveys, were conducted at 26 sites in Iowa. Findings show that specific gravities of RPCC are lower than those of crushed limestone. RPCC aggregate material varies from poorly or well-graded sand to gravel. A modified Micro-Deval test procedure showed that abrasion losses of virgin aggregate materials were within the maximum Micro-Deval abrasion loss of 30% recommended by ASTM D6028-06. Micro-Deval abrasion loss of RPCC aggregate materials, however were much higher than those of virgin materials and exceeded 30% loss. Modulus of elasticity of RPCC subbase materials is high but variable. RPCC subbase layers normally have low permeability. The pavement surfaces for both virgin and RPCC subbase across Iowa were evaluated to fulfill the objectives of this study related to field evaluation. Visual distress surveys were conducted to gather the detailed current pavement condition information including the type, extent, and severity of the pavement distresses. The historical pavement condition information for the surveyed field sections was extracted from the Iowa DOT's Pavement Management Information System (PMIS). The current surface condition of existing field pavements with RPCC subbase was compared with the virgin aggregate subbase sections using two different approaches. The changes in pavement condition indices (PCI and IRI) with time for both types of pavements (subbases) were compared.

Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: This book describes how, given the global challenge of a shortage of natural resources in the 21st century, the recycling of waste concrete is one of the most important means of implementing sustainable construction development strategies. Firstly, the book presents key findings on the micro- and meso-structure of recycled aggregate concrete (RAC), while the second part focuses on the mechanical properties of RAC: the strength, elastic modulus, Poisson’s ratio, stress-strain curve, etc. The third part of the book explores research on the durability of RAC: carbonization, chloride penetration, shrinkage and creep. It then presents key information on the mechanical behavior and seismic performance of RAC elements and structures: beams, columns, slabs, beam-column joints, and frames. Lastly, the book puts forward design guidelines for recycled aggregate concrete structures. Taken as a whole, the research results – based on a series of investigations the author has condu cted on the mechanical properties, durability and structural performance of recycled aggregate concrete (RAC) over the past 10 years – demonstrate that, with proper design and construction, it is safe and feasible to utilize RAC structures in civil engineering applications. The book will greatly benefit researchers, postgraduates, and engineers in civil engineering with an interest in this field.

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.
