摘要：	The Federal Highway Administration (FHWA) has initiated an applied research program for using composite materials in highway structures. A lack of practical analysis, design, and failure-prediction capabilities has led FHWA to study, evaluate, and develop the knowledge base of fiber-reinforced polymer (FRP)-composite materials for bridge and auxiliary roadside structures. The impetus for such a program is related to the large number of aging bridge structures nationwide that are deteriorating due to severe outdoor corrosive elements. This article examines the twofold research program on composite bridge structures and roadside structures. Regarding composite bridge structures, the authors report on program scope, material characterization and design methodology development, and construction applications. Under composite roadside structures, the authors highlight program scope, performance requirements, roadside rail system development, developmental testing and analysis, and manufactured part fabrication and compliance testing. The "yardsticks" against which this applied research program will be measured are field implementation and private sector involvement.
