| Abstract | This is an investigation of methods for the design and construction of a temporary runway to be built on a foundation of saturated clay soil. The main purpose of the experiment was to devise a means of utilizing the native soil as a source of material for construction of an embankment. The clay to be used for the embankment was, in the first trial, placed in polyethylene bags and compacted in a mould to form a soil block 40 cm x 35 cm having 10-cm height; the soil was left in the bag. It was anticipated that the compacted clay in the bags would remain at constant moisture content and would be suitable for building an embankment. Another trial was conducted using clay soil at natural water content and placed uncompacted in the bags. This second experiment was to provide a comparison with that of the airdried, compacted soil model. In a third trial, cutback asphalt was used to improve the sealing of the bags and to provide adhesion between the individual units of bagged soil which would comprise the embankment. It was concluded that, no matter which method was used, the clay in the bags should be kept at constant moisture content to assure the stability of the embankment when inundated. The study indicated that the bagged soil serves both as a surcharge which consolidates the natural subgrade of saturated clay, as well as providing higher strength material for the embankment. |
