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.

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

Book Description
Water quantity—too much in the case of floods, or too little in the case of droughts—grabs public attention and the media spotlight. Water quality—being predominantly invisible and hard to detect—goes largely unnoticed. Quality Unknown: The Invisible Water Crisis presents new evidence and new data that call urgent attention to the hidden dangers lying beneath water’s surface. It shows how poor water quality stalls economic progress, stymies human potential, and reduces food production. Quality Unknown examines the effects of water quality on economic growth and finds upstream pollution lowers growth in downstream regions. It reveals that some of the most ubiquitous contaminants in water, such as nitrates and salt, have impacts that are larger, deeper, and wider than has been acknowledged. And it traces the damage to crop yields and the stark implications for food security in affected regions. An important step toward tackling the world’s water quality challenge is recognizing its scale. The world needs reliable, accurate, and comprehensive information so that policy makers can have new insights, decision making can be evidence based, and citizens can call for action. The report calls for a paradigm shift that emphasizes safer, and often more cost-effective remedies that prevent pollution by combining smarter policies with newer technologies. A key message of Quality Unknown is that such solutions exist and change is possible.

Book Description
Rural roads constitute the most dangerous road category with regard to the number of fatal accidents. In order to increase traffic safety on rural roads it is necessary to take into account not only their inherent properties but also their effect on behaviour. Gert Weller develops a psychological model for driving on rural roads which is validated in three empirical steps: laboratory, simulator and driving experiments. His results provide insight into the possibilities of how driving behaviour on rural roads can be influenced and give practical guidance for the enhancement of rural road safety. The book is written for psychologists in the fields of traffic psychology and human factors research, traffic engineers, road planners as well as for political decision makers in traffic planning departments.
