Frequently Asked Questions
Why does road base use a different density than loose gravel?
Road base is compacted after placement, which packs the material tighter and increases its density compared to loose gravel. This calculator applies a compacted density of 1.75 tons per cubic yard directly to the compacted depth you enter, a common simplified approach for material estimates.
How deep should a road base layer be?
A common range is 4 to 6 inches for a residential driveway base, and more for heavier vehicle traffic. Check local guidance for your specific application.
Should I order extra road base material to allow for compaction?
Many contractors order extra loose material since compaction reduces volume. This calculator estimates the compacted-in-place amount; ask your supplier for their recommended loose-to-compacted ratio if ordering by the truckload.
