Abstract
Field experiments were carried out to determine the possibility of improving the bedding ability of a mortar baseplate into frozen ground and other hard surfaces. The methods investigated were: styrofoam shoes, shaped charges, removable steel shoes with cutting edges, cutting edges fixed to spades, a frame and spike attachment and finally an integral spike arrangement. Results indicated that integral spike arrangement has greatly improved the stability of the baseplate on hard frozen ground as well as on asphalt. Although the tests were carried out using a standard 81mm baseplate to facilitate the program, this concept could be incorporated to any baseplate.
