The use of porous pavements in creating the infrastructure of the urban environment

Introduction. Considered green construction, which is carried out in accordance with the environmental expediency. A list of environmental problems associated with the impermeability of soil covering cities is given and measures are proposed to eliminate the negative effects of human activity on the environment. Materials and methods. Researched the use of porous pavements, as a means of combating environmental problems and creating a favorable urban environment. The definition of a porous pavement and its difference from the usual road surface is given. A description is given of the component parts of the paving system, including the base, filter cloth, filler tank and porous surface layer. The main types of porous coatings, such as porous concrete, porous asphalt and paving stones are analyzed. It is considered the environmental, aesthetic and economic benefits of porous pavements: replenishing the groundwater supply, combating floods as a result of reducing the volume of storm water, preserving plants in the urban environment, controlling the urban heat regime, cooling the surface waters of rivers and other water bodies, improving traffic safety, monitoring noise. Results. It is presented situations in which the use of porous pavements is not effective. These are, for example, highways with heavy traffic, steep slopes, areas with erosion and soil erosion, roads where chemical reagents are actively used to control ice in the winter, places of likely spills of harmful substances. It is noted that in order to effectively use porous pavements, they must be properly maintained depending on the type of porous pavement. Recommendations on the use of porous pavements are given. Conclusions. Due to their peculiarities, porous pavements cannot be applied everywhere, but this option of pavements should be considered by all capital construction participants interested in introducing green building technologies in our country.
