Remediation of Petroleum-contaminated Soils PDF Author: David J. Friend
Publisher: Transportation Research Board
ISBN: 9780309058711
Category : Technology & Engineering
Languages : en
Pages : 100

Book Description
This synthesis will be of interest to state transportation personnel involved with project planning and location (administrative and regulatory personnel), design staff (general civil, geotechnical, and environmental engineers), and project managers (construction and maintenance engineers and staff). It will also be of interest to federal and state environmental agencies and to environmental consultants and contractors as well as to trainers in the field of petroleum-contaminated soil remediation. This synthesis describes the remedial technologies that may be available to transportation agencies faced with the regulatory responsibility to clean or remediate petroleum-contaminated soils in the vadose zone (unsaturated soils above the groundwater table) at a particular site as well as the state of the practice within the agencies. This report of the Transportation Research Board describes the applicability and cost-effectiveness of alternate technologies to remediate petroleum-contaminated soil. Practices currently being used by state transportation agencies to remediate petroleum-contaminated soils, both on site and off site are also described. This summary of transportation agency practice complements the limited telephone survey of soil remediation techniques that was performed in preparing NCHRP Report 351, Hazardous Wastes in Highway Rights-of-Way.

Best Management Practices for Environmental Issues Related to Highway and Street Maintenance PDF Author: William Albert Hyman
Publisher: Transportation Research Board
ISBN: 9780309068505
Category : Technology & Engineering
Languages : en
Pages : 116

Book Description
This synthesis report will be of interest to state, local, and federal agency environmental and maintenance administrators, directors, supervisors, engineers, and scientists. It describes current best management practices (BMPs) for environmental issues related to road and street maintenance. The synthesis documents relevant background and recent information with regard to management practices that can help protect, preserve, or enhance the environment while at the same time allow road maintenance organizations to carry out their fundamental mission of maintenance and repair in a cost-effective manner. Information for the synthesis was collected by surveying U.S. and Canadian state and local transportation agencies and by conducting a literature search using domestic sources. This report of the Transportation Research Board describes BMPs consisting of broad management approaches applicable to the entire maintenance program or to more than one program area. In addition, BMPs for specific maintenance activities or groups of maintenance activities are included. Finally, BMPs concerning specific environmental issues are discussed.

Assessing the Effects of Highway-widening Improvements on Urban and Suburban Areas

Assessing the Effects of Highway-widening Improvements on Urban and Suburban Areas PDF Author: Thomas Nelson Harvey
Publisher: Transportation Research Board
ISBN: 9780309058650
Category : Nature
Languages : en
Pages : 56

Book Description
This synthesis will be of interest to highway environmental specialists (particularly those concerned with assessing social and economic impacts), design engineers, planners, utility managers, and others responsible for the planning, design, and implementation of highway-widening improvements. Information is presented on the reasons for highway-widening projects, the nature of the projects, and the methods and practices for application of analytical techniques used to measure the potential or actual impacts of the projects on people and the physical environment. Mitigation measures are also discussed. This report of the Transportation Research Board describes the most recent widening projects as reported by states or other transportation agencies, as well as the most frequently encountered issues in highway widening. Selected examples of widening projects are included, as is some recognition of the need for additional information and research in the areas of social and economic impact measurement.

Truck Escape Ramps

Truck Escape Ramps PDF Author: David K. Witheford
Publisher: Transportation Research Board
ISBN: 9780309053051
Category : Roads
Languages : en
Pages : 68

Book Description
This synthesis will be of interest to highway design engineers, maintenance personnel, safety and enforcement officials, traffic engineers, and others responsible for the safe operation of large trucks on highways. Information is provided on the critical aspects of site location, design criteria, and maintenance procedures, and their relationship to truck escape ramp performance. The safety of truck drivers, other road users, and occupants of roadside properties is often imperiled by the combination of heavy trucks and steep downgrades on highways. Frequently, gearing down, applying the brakes, and using the retarding power of the engine are not sufficient to control the truck, and serious crashes can result. Many states have constructed truck escape ramps to safely remove runaway trucks from the traffic stream. This report of the Transportation Research Board provides information on the location, design, construction materials, geometrics, and construction costs of truck escape ramps. Operational considerations, such as descriptions of advance warning signs, traffic control devices at the ramp, and vehicle removal procedures are described. Information on frequency and type of usage, maintenance of the ramps, and driver-related issues is also included.
