Order at least 48 tons of Road base (compacted).

  • You need approximately 26.83 cubic yards (20.52 m3) of Road base (compacted) to complete this project.
  • That is about 47.04 US short tons. Most suppliers sell by the ton, so round up to the nearest full ton when placing your order.
  • A compaction allowance of 15% and a waste factor of 5% are already included in that figure.

Next stepOrder material in advance and confirm moisture content with your supplier - road base should be within 1-2% of optimum moisture content for best compaction.
