Samenvatting

Research relating compaction to performance properties indicates that the benefits of better compaction are considerable. In order to improve compaction, modified rolling procedures have been formulated to ensure that greater compactive effort was applied before the material had cooled excessively. An improved method specification met with limited success. An alternative way of achieving the necessary improvement in compaction is to set compaction targets but this requires a satisfactory means of assessing the end result. A refusal test which was originally developed to determine the scope for further compaction was found to offer considerable potential as a standard. (Author/publisher)
