Research Report 112 Use of melter slag as aggregate in open-graded emulsion mixes

Published: | Category: Activity management , Research programme , Research & reports | Audience: General

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.
