The Poisson's ratio of compacted bituminous mixtures

Project: Research project

Project Details


The knowledge and use of the Poisson's ratio in methods of mixture and pavement design is of primary importance. Test methods to find realistic values, however, are not very common. Mostly they are rather sophisticated and therefor not used in daily laboratory practice. In an Austrian R&D-project a new device has been developed which is able to measure the deformation of test specimens by mean of a video camera, the connected software allows to evaluate the ration simultaneously. In this stdy the Poisson's ration is investigated using Marshall test specimens, both in Marshal tests as well as in indirect tensile tests. Different mixture types will be tested under different test conditions (temperature and deformation rate). In this study a new device has
