Research of bituminous mixtures with higher resistance to chemical ageing, to fatigue caused by traffic loading and higher resistance to temperature influence of very high and very low temperature caused by climatic changes. Evaluation of glass grid reinforcement on bituminous layer resistances. Laboratory testing of test samples, construction elements and pavement structures. Realisation of new technologies in case of road construction and repair and long term evaluation of that section. Application of new technologies in technical recommendation pavement design, design of maintenance and repair and in technological recommendation and standards.
