Recent research shows that biochar has the potential to improve the chemical, physical and biological properties of soils, which is also reflected in the crops. Because biochar is not a homogeneous material and it often needs to be activated to see its positive effects, it is very important to pay attention to its properties and subsequently to thoroughly verify it in agricultural practice. For this reason, experiments were carried out on two texture different soils (1. Dolna Streda: sandy soil, 2. Velke Ulany: lo...

The asphalt pavement materials which are after the Life cycle can be used in the production of new asphalt mixtures. If its quality of material is not suitable for the production of asphalt mixtures (inhomogeneity of material, soil content, etc.), the material can be used in unbound layers of pavements. The Road materials (new or recycled) are exposed during the operation to the effects of traffic loads and climatic influences, in particular changes in air and humidity temperatures, which are reflected by cyclical...
