    Abstract

    Engineering and compaction characteristics of boiler slag are presented. Laboratory and field compaction tests are conducted in assessment of these characteristics. Field tests are conducted on a slag fill of 0.92 m (3 ft) in thickness. A smooth drum vibratory roller 56 kN (12.5 kips) is used for compaction. The densification is evaluated after 2, 4, 6, 10 and 16 passes of this roller. A methodology is presented for estimating the lift thickness and the number of passes required for a desired level of densification.

    Keywords:

    compaction, slag, lift thickness, roller pass, friction angle, cohesion intercept, relative density, specific gravity
