Unpaved Road Dust Management, A Successful Practitioner's Handbook (2013)
This handbook provides broad programmatic aspects of unpaved road management. It is based on observations made during a national scan tour and provides useful and insightful excerpts of real world examples and includes practical how-to instructions for determining what type of treatment may be needed for different situations.
Unpaved Road Chemical Treatments State of the Practice Survey (2013)
This report documents survey results regarding the state of the practice of using chemical treatments on unpaved roads. It provides insights into road manager choices and challenges.
An Integrated Approach to Sustainable Roadside Design and Restoration (2013)
The roadside represents the interface between the roadway and the surrounding environment, and plays an important role in protecting the larger ecosystem. Roadsides are dynamic environments that require unique treatments and restoration approaches. This guide presents an integrated and holistic approach to incorporating sustainable solutions into disciplines such as hydraulic, geotechnical, aesthetics and vegetation, among others.
Integrated Approach for Building Sustainable Roads (2013
Recent emphasis on sustainability in the field of transportation has resulted in newly developed sustainability technical guidance, such as sustainability evaluation tools and technical documents. This document provides an approach for practitioners to integrate sustainability into the planning, design, and construction of projects and is intended to be compatible with an owner's existing technical guidance for project development processes.
Wildlife Crossing Structure Handbook Design and Evaluation in North America (2011)
This handbook provides numerous solutions to wildlife-vehicle interactions by offering effective and safe wildlife crossing examples. Key design and ecological criteria, construction and maintenance guidelines, and effective monitoring techniques are shown and described in this handbook's practical application examples called Hot Sheets.
Best Management Practices for Chemical Treatment Systems for Construction Stormwater and Dewatering (2009)
Chemical treatment systems (CTS) are implemented in areas where traditional, physical erosion and sediment control practices will not meet water quality goals for construction site runoff. This report provides a technically credible basis for best management practices for the use of CTS for turbidity reduction on road construction projects and identifies the most important variables to address when selecting chemical treatment best management practices for a particular site.
Context Sensitive Rock Slope Design Solutions (2011)
Context sensitive designs in transportation are key to developing facilities that fit within the engineered setting, preserving scenic, aesthetic, historic and environmental resources while maintaining motorist safety and mobility. This report provides design, construction, and maintenance solutions for rock slope excavation, stabilization, and mitigation in context sensitive regions. It addresses state-of-the-art and state-of-practice technologies for the evaluation, design, and construction of context sensitive rock slopes.
Rockery Design and Construction Guidelines (2006)
Rockeries consist of earth retaining and/or protection structures comprised of interlocking, dry-stacked rocks without mortar or steel reinforcement. The report provides a rational design methodology, which evaluates rockery stability as a function of the rockery geometry (height, base width, and batter), rock properties and placement, and lateral pressure imposed by the backfill materials.
