In the last years some laboratorial tests are used to predict the permanent deformation behaviour ofbituminous mixtures. Among those tests the Wheel Tracking test, the Cyclic Compression Test (Uniaxial andTriaxial) and the Repetitive Shear at Constant Height (RSCH) test, are considered for Portuguese practice. Alsocome out recently new European standards for those tests, with exception of the RSCH which is essentially usedin the USA. Nevertheless some of testing conditions are not very well defined. Therefore, it is important to studythe reliability and accuracy of each test in the task of predicting permanent deformation behaviour. In this workthese test were used in the evaluation of a commonly used mixture in Portugal. Results show that all tests aresuitable for predicting permanent deformation behaviour. Thus simpler and cheaper tests are more interesting touse.
