Abstract: In the Czech Republic, an intensive preparation of the construction of high-speed lines according to the principles adopted from France has currently been underway. Its substructure is among others to be made of a layer of asphalt concrete. However, the stiffness requirements of such an asphalt mixture cannot simply be taken from the French standards because in the Czech Republic, a different type of test methods for its determination is more commonly used. This paper describes an experimental study that compares the results of the asphalt mixture stiffness determined by the 2PBTR method used in France and the ITCY method which is frequently used in the Czech Republic (as well as in the United Kingdom). As part of the study evaluation, a mutual correlation between the individual methods is found for the results.
