Abstract:

The purposes of the investigation reported herein were to a determine the techniques required to construct a waterproof fine-grained soil base course by encasing the soil layer in a protective membrane envelope, b evaluate several types of membranes for use in this waterproofing technique, and c determine the effects of aircraft traffic under a range of weather conditions on a base course so constructed. A test section was constructed having a a highly compacted lean clay base course over a low strength subgrade of the same soil, and b a heavy clay base course over a loose sand subgrade. During construction, various surface and subsurface membranes were bonded together to form a single watertight envelope encasing both base courses.
