摘要

In 1991 the Washington State legislature required the state department of transportation to study the use of recycled materials for road construction. The major objectives of the study were to examine which types of recycled materials, such as glass and discarded tires, are appropriate and feasible as alternative paving materials; and which types of recycled materials, such as mixed plastics and compost, are useful in transportation applications other than pavements. The study was to be conducted in concert with the Clean Washington Center, a department of the Washington State Department of Trade and Economic Development that promotes the development of markets for certain recycled materials.
