The thesis deals with the experimental determination of the resilient modulus using cyclic triaxial test with the selected unbound mixtures of the base course of the pavement. The aim is to verify whether the proposed modulus-resilient in the regulation TP 170 based on the statisticaly verified data dating several decades ago is still valid in the present. Furthermore, the thesis deals with the dependence between the measured and the calculated values of the modulus resilient Mr from the cyclic triaxial test and the California Bearing Ratio tests. For the classification of the selected materials, further tests are used in the thesis, such as granularity and compaction tests.
