The paper presents the results of previous researches of different mixtures of pervious concrete pavements in the world, as well as the advantages and disadvantages of the structural formation on the mechanical properties of porous concrete. The porosity of pervious concrete ranges from 15% to 35%. The most important properties of pervious concrete pavement were analyzed: compressive strength, flexural strength, splitting tensile strength, frost resistance and abrasion resistance. Different types of aggregates (natural, recycled), different fractions and granulometric composition of aggregates, different amounts of fine aggregate, different types and amounts of additives in pervious concrete and various water-cement ratio, were used in the analyzed studies. According to obtained results, the relationship between the most important properties of pervious concrete and its porosity was established. It was concluded that increasing of the porosity directly affects to decreasing of the concrete compressive strength and frost resistance, while abrasion resistance is increasing.
