Soil Stabilization Investigation for 155 mm Towed Howitzer Firing Pads.
Abstract
The 155 mm Howitzer is placed in its firing configuration by jacking it off its road wheels onto a base place support. The trails are spread and the trail spades are dug into the ground. During normal firing, the recoil of the weapon is absorbed by the base plate, recoil mechanism, and trail spades. Frequently, the Howitzer must be positioned in soils which have low shear strength and/or high water content. When the Howitzer recoils, the trail spades shear the soil permitting excessive lateral displacement. This can lead to inaccurate artillery fire or even a cease fire condition during a fire mission. The objective of this study was to determine the feasibility of using lime-soil stabilization as a technique to provide a stable firing platform for the 155 mm Howitzer. Variables evaluated included lime content, moisture content, compactive effort, and curing time; all factors bearing on field construction and operations. (Modified author abstract)
