A Predictive Approach for Long-Term Performance of Recycled Materials Using Accelerated Aging, Volume I: Final Report
FHWA-RD-01-022
This report analyzes the long-term physical and environmental performance of recycled materials in a highway application. The use of recycled
materials in a proposed highway application frequently requires the assessment of physical and environmental performance. Future behavior is often difficult to predict. As alternatives to field demonstrations, strategies to predict long-term physical and environmental performance need to be developed.

Assessment of Highway Particulate Impacts: Phase I, Task
A-Problem Evaluation, Final Report
FHWA-RD-99-180
This report provides an assessment of highway particulate impacts. It evaluates existing knowledge on (1) the sources of particulates,
especially those specific to highways; (2) methods of assessing particulate
impacts from highway sources; (3) relationships between highway-derived particulates and
other particulate sources; (4) particulate instrumentation, measurement, and monitoring methods; (5) assessment of
potential public health risks; and (6) control strategies for lessening the impact of highway particulates.www.ntis.gov, PB99-175705
Assessment of Highway Particulate Impacts: Phase I, Tasks B
and C-Field Sampling and Evaluation Program, Final Report
FHWA-RD-99-181
This report is the second of two reports developed as part of Phase I of a study on highway particulate impacts. Researchers investigated four sources of highway particulate emissions: (1) emissions from
diesel-powered vehicles, (2) emissions from road sanding and salting operations, (3) dust from paved roadways, and (4) emissions from unpaved roadways.

Development and Validation of Light-Duty Vehicle Modal Emissions and Fuel Consumption Values for Traffic Models
FHWA-RD-99-068
This report presents a methodology for modal-vehicle
emissions and fuel-consumption models. These models are designed for
simulations, such as the Federal Highway Administration's TRAF series of
traffic simulation models, and are used to evaluate the impacts of roadway design on emissions and fuel
consumption.

Framework for Evaluating the Use of Recycled Materials in the Highway environment
FHWA-RD-00-140
This report provides a recommended evaluation methodology
for determining the suitability of using recycled materials in highway
construction. The manual is intended as a reference for highway and
environmental engineers interested in using recycled materials in the highway
environment.

Implementing Bicycle Improvements at the Local Level
FHWA-RD-98-105
This implementation manual is intended for local governments that want to improve conditions that affect bicycling. It is designed to help local public works or transportation departments identify specific problems and deal with them as part of the agency's routine functions. Researchers considered 13 of the most typical situations or factors that impact bicycle use. For each situation or factor, the manual provides a problem overview, solution overview, implementation strategies, objectives, resource requirements, subtasks, schedule,
specifications, and references.
