If more than 150 mm, the aggregate subbase shall spread and compacted in two (2) layers of approximated equal thickness, and maximum compacted thickness of any one layer shall not exceed 150 mm.
These subbase aggregates are often cheaper than their quarried equivalents and have similar technical specification. Many of the recycled sub base aggregates available are fully certificated enabling them to be used on most construction projects. *Please Select a Recycled SubBase Aggregate Below for More Information*
