Melter slag is a major by-product of the steel manufacturing process, and its potential for use as an aggregate in open-graded emulsion mixes (OGEMs), is the topic of this report.
Crushed melter slag was first tested in 1991 for use in constructing access roads within a steel mill complex in New Zealand. Its performance was later trialled on a state highway intersection for about 4 years (1994–1997).
The report details the results of the monitoring and evaluates its use as aggregate.
