Chalk materials (A8.2)

A8.2.1: All chalk materials, including medium and high-density chalks must be compacted in accordance with Table A8.2. However, if the chalk is unstable after compaction, it must be removed and replaced with fresh material. Fresh chalk must be compacted in accordance with Table A8.2 except that the specified number of compaction passes must be reduced by one pass. If the chalk is still unstable after compaction, it must be replaced with suitable material.
