Best Practices Guide for the Use of Recycled Materials in Transportation Infrastructure (2013)

Historically, the methods that have been used for evaluating the engineering and environmental suitability of new potentially recyclable materials have varied significantly across jurisdictions.  As a consequence, both an ‘applicant’ (who might be an agency, constructor or supplier) who desires to use a recycled material, and a ‘decision maker’ (owners, specifiers or designers) who must determine the suitability of the application, in many cases do not have a clear or consistent approach (an evaluation framework) that can be used to proceed with such an evaluation.

The objective of this document is to provide a guide for use by agencies in identifying the various types of recycled materials and technologies which are available to them, along with their most practical/successful uses in transportation infrastructure applications.

The focus of the document is on waste and industrial by-product materials that are suitable as replacements for natural aggregates in transportation infrastructure projects.  Twenty-two materials have been evaluated and grouped into six main categories: asphalt concrete, portland cement concrete, granular base and subbase materials, embankment and fill construction, stabilized bases and flowable fills.
