Abstract:

This document contains recommendations for best practices related to the use of air-cooled blast furnace slag (ACBFS) as coarse aggregate in concrete pavements. It is primarily based on the results of a review of available literature regarding the production and use of ACBFS as coarse aggregate in concrete pavements, information provided through interaction with the project’s expert task group, and limited pavement field surveys and petrographic analysis of extracted cores from ACBFS concrete pavements.

This best practices document discusses the production, physical, and chemical properties of ACBFS aggregate, highlighting how this material differs from natural aggregates. It also discusses the properties of concrete produced with ACBFS coarse aggregate and identifies specific production issues and quality control practices applicable to ACBFS concrete. The document further provides design and construction recommendations for improving the quality of concrete pavement made using this material. Results from field inspections and laboratory evaluations of concrete pavements made with ACBFS coarse aggregate are discussed. Finally, the life-cycle and maintenance costs associated with concrete pavements incorporating ACBFS aggregate in the concrete are also discussed in the report.
