Foreword

The Federal Highway Administration (FHWA) encourages programs that protect both the environment and the life of the roadway. Fugitive dust from unpaved roads threatens air, soil and water quality and roadside flora and fauna. This loss of material cause road surface deterioration, increases maintenance cost, and adds to the complexity of managing a network of unpaved roads.

This FHWA report called Unpaved Road Dust Management, A Successful Practitioner's Handbook offers broad programmatic-level guidance for managing a cost-effective unpaved road program. This handbook is for all managers of unpaved roads who seek to stretch their budgets to provide an acceptable level of service while minimizing risks to air, soil and water quality, vegetation and wildlife.

16. Abstract

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. It ultimately strives to encourage road managers to think broadly about the process of unpaved road management rather than just focusing on a specific type of chemical treatment.
17. Key Words

FUGITIVE ROAD DUST, DUST CONTROL, CHEMICAL TREATMENT(S), UNPAVED, GRAVEL, UNSEALED ROADS, PALLIATIVES, STABILIZATION, UNPAVED ROAD MANAGEMENT
