At present, intensive urbanization is taking place while the effects of global warming are becoming increasingly pronounced. One of the significant consequences of these trends is the growing intensity of the urban heat island effect, which negatively affects the urban microclimate as well as the quality of life of city inhabitants. One possible way to mitigate these impacts is the use of blue-green infrastructure elements, including permeable pavements. This diploma thesis deals with the study of selected properties of superabsorbent polymers based on sodium polyacrylate and potassium polyacrylate with regard to their potential use in hydroabsorbent mixtures intended for the aggregate layer of permeable pavements. The course of water absorption and desorption, the influence of the ionic composition of the absorption medium on the current and subsequent absorption properties of SAPs, and the stability of their function during repeated absorption/desorption cycles were evaluated experimentally. The thesis  also included an assessment of the effect of adding ground zeolite on the stabilization of the absorption properties of the polymers and an evaluation of selected types of aggregate for the design of a hydroabsorbent mixture for the aggregate layer of the pavement structure. It was found that sodium polyacrylate exhibited a higher absorption capacity than potassium polyacrylate. At the same time, it was confirmed that multivalent cations in the absorption medium significantly reduce the absorption ability of SAPs. The addition of zeolite showed a partial stabilizing effect in an ionic environment. Of the evaluated aggregate types, coarse-fraction concrete recyclate appeared to be the most suitable for the theoretical design of the reservoir layer.
