Use of Air-Cooled Blast Furnace Slag as Coarse Aggregate in Concrete Pavements - Final Report

General Interest: provides practical guidance to engineers responsible for the day-to-day design, construction, rehabilitation, maintenance, and management of pavements.

Primary Topic: Materials-Concrete

Description: This report presents available information regarding the use of air-cooled blast furnace slag (ACBFS) as coarse aggregate in concrete pavements. The report discusses ACBFS aggregate production and properties, and the properties of concrete produced with ACBFS coarse aggregate. Both the physical and chemical properties of ACBFS are presented, as are the properties of the concrete produced with ACBFS coarse aggregate. Additionally, the field performance of concrete pavements containing ACBFS coarse aggregate and observed material related distresses in these pavements are presented, along with results from laboratory evaluations of concrete containing ACBFS coarse aggregate. Finally, the life-cycle and maintenance costs associated with concrete pavements incorporating ACBFS aggregate in the concrete are also discussed in the report.
