RAPID OEDOMETER TESTS

SNABBA OEDOMETERFOERSOEK

The aim of the project was to investigate whether conventional oedometers for step-by-step load could be utilized more efficiently. The standard procedure is one load per day during one week. In this investigation the load was increased as soon as the primary consolidation was completed and each experiment thereby was performed during one day. A comparison between conventional test and rapid test shows that the rapid test gives a higher preconsolidation pressure. The difference is of minor importance if the preconsolidation pressure is evaluated at the maximum bending of the compression curve. The compression index is equal for both tests. The minimum value of the coefficient of consolidation is generally higher with rapid tests. Finally some recommendations concerning the carrying out of rapid tests are given. /TRRL/
