Abstract

In a geotechnical design of a foundation, proper soil parameters are needed to perform a proper design. In some regions, cretacious soils, such as chalk, are deposited near the ground surface. Hence, they will be the bearing stratum for a foundation. However, chalk is a very brittle material and the sample preparation for laboratory tests is very challanging. This paper presents two methods to prepare chalk samples for oedometer testing, where one showed to have a significantly higher success rate compared to the other. Additionally, the paper presents results from oedometer tests on chalk from Rørdal, Denmark.
