Abstract

A new European standard for cyclic triaxial testing of unbound granular materials was approved by CEN in 2004. In the final stages of preparation of the standard it was decided to organize a round robin analysis with invitation to laboratories in Europe that have been doing research using this type of tests. Nine different laboratories received the material and six laboratories performed the tests. Only one material at one target dry density and water content was investigated. Most of the laboratories performed three parallel tests. This is obviously too few tests for a statistically sound validation of the tests. However, some indication about the accuracy of the test was found.
