Described in this paper are test procedures and resulting data used in the laboratory to evaluate the absorption of water and the swelling pressures of several different mixtures of a particular acrylate grout when placed in situ. The water absorption characteristics were determined for both neat grout and grouted sand under conditions of either free swell or moderate confinement. Swelling ...
Data were collected and reviewed pertaining to one-dimensional vertical free-swell tests performed on existing fill soils from various projects located in Southern California. The purpose of reviewing the data was to evaluate the effect of overburden pressure on the swelling potential of expansive soils. The swell tests were performed on relatively undisturbed specimens at the in-place moisture ...
An experimental study has been conducted to study the swelling pressure behavior of expansive soil in both vertical and lateral directions simultaneously under controlled suction. A series of one-dimensional consolidation tests was carried out on compacted soil specimen using a newly developed oedometer with devices for controlling suction and measuring lateral pressure. The test results show ...
