Price Check 3/4 Gravel
Small 6-wheeled dumps (F750-800 size) generally carry 7 yards. Also, don't be surprised if you end up getting considerably more than you think you'll need - material doesn't go far. I made a little french drain this summer that was only about 100' long - it required a full 24 ton tri-axle load of crushed stone.

Influence of Emergency Braking on Changes of the Axle Load …
Fig. 5. Dynamic internal friction factors of selected kinds of gravel and stone Source: authors according own measurements. Table 3 presents results of the braking tests and the influence of braking on loads on the tractor and its driving axle. The load on the semi-trailer tri-axle decreased by the same weight as the load on the tractor increased.

Equivalent Single Axle Load
Similarly, a 97.8 kN (22,000 lbs) single axle needs to be repeated less than half the number of times of an 80 kN (18,000 lbs) single axle to have an equivalent effect. An 80 kN (18,000 lbs) single axle does over 3,000 times more damage to a pavement than an 8.9 kN (2,000 lbs) single axle (1.000/0.0003 ˜ 3,333).
