Dynamiska treaxialförsök på VTI: jämförelse mellan VTI-metoder och EN 13286-7
Swedish National Road and Transport Research Institute.

Abstract [sv]

At VTI cyclic load triaxial tests on pavement structure materials have been performed since 1993. The methods for this has been developed at VTI with some inspiration from among others USA. The VTI methods are named after the unbound layers of the pavement structure (baselayer test, sub-baselayer test and capping layer test). During the year 2004 the European standard EN 13286-7 "Cyclic load triaxial test for unbound mixtures" came which meant other loadings and other ways of studying permanent deformation and resilient behaviour. VTI participated in a round robin test for resilient behaviour according to the European standard during 2004. Later the same year three different kinds of bottom ashes were tested with both VTI's capping layer test and the European standard test for permanent deformation. In this work there were three main purposes: - To learn how European standard works and what it means to test according to the standard. It has been achieved by simply starting to use it. - To compare results between VTI methods and the European standard, this showed to be complicated. You can partly do this for resilient behaviour but it is more difficult for permanent behaviour. - To describe in detail how to perform cyclic load triaxial tests at VTI.
