The paper deals with the analysis of pavement layers behaviour under simulated traffic loading. The road structure of a category one road designed according to the technical recommendations for pavement design in the Czech Republic (TP 170 supplement No 1.) is subjected to long term dynamic impulse loading applied through the contact surfaces of dual wheel assembly mounted on heavy goods vehicle axle. [1] The model is equipped with several sensors for measuring stress, horizontal strain, temperature, and moisture. The results of the measurements provide information on the changes in the condition of the pavement layers in terms of long-term monitoring of stresses and strains, the development of permanent deformations and the interaction between various structural layers. Combined with the different structures tested, this research will lead to a detailed description of the behaviour of the strength and deformation characteristics of the pavement layers and refined specification of pavement design.
