Restoration of Landing-Mat-Surfaced Subgrades by Grouting Methods.
Abstract
Engineering tests have been conducted at WES to determine methods of repairing damaged subgrades beneath landing mats by grouting. Use of portland cement grout consisting of portland cement, CaCl2, water, and filler is effective to a limited extent. The grout can be pumped through 1-in. diam holes drilled into the mat by use of a satisfactory grout pump. Suggested equipment includes a truck, concrete mixer, air compressor and pneumatic drill, grout pump, and a water truck.
