A small loader has a frame, and drive tracks on opposite sides of the frame. The, drive tracks are mounted over drive sprockets and idler wheels to establish lengths of track at upper sides. The frame includes upright members at a rear portion for mounting a lift arm assembly made of two lift arms joined together. Each lift arm has a rear portion pivotally mounted on the upright portion of the frame and extending downwardly and forwardly to join side portions of the lift arms that are substantially parallel to the upper lengths of the respective tracks in a lowered position of the lift arm assembly. Actuators for pivoting the lift arm assembly are mounted on the frame, below the side portions and above the tracks, and extend generally parallel to both the side portions and the upper length of the tracks when the lift arm assembly is in a lowered position.

A fluid, aerated material is formed by mixing the particulate solid material with finished foam. The aerated material may also include cement or another binder for applications requiring structural strength. The bubble structure which results from incorporating the foam constituent in the fill material renders this much more fluid and pumpable, thereby allowing the use of much higher solids-to-water ratios than would otherwise be possible while still being able to pump the material over significant distances. This reduces the possibly of fluidic collapse of the material in the void, and produces other advantages as well.
