MECHANICAL STABILIZATION FOR THE CONTROL OF FROST HEAVE

Three types of coarse particle (slag, basalt, limestone) were assessed as stabilizing agents, and these were each subdivided into two particle size groups: 20-3.35 mm and 37.5-20 mm. The basic soil matrix consisted of a highly susceptible mixture of sand and ground chalk. Heave was measured over a 250 hour period of cylindrical specimens subjected to the transport and Road Research Laboratory (United Kingdom) frost heave test. It was found that the introduction of coarse aggregate to the frost-susceptible matrix leads to a decrease in frost heave and heaving pressure. The influence of the coarse aggregate was very dependent on aggregate type but less dependent on aggregate size. The slag aggregate was found to produce the largest reductions. (TRRL)
