Prospects of using penetrated cement concrete in the construction of transport infrastructure objects

This article presents the analysis of the international experience of the use of pervious concrete in transport infrastructure. It provides the advantages and disadvantages of the material and the results of personal laboratory tests of relevant concrete samples. The object of the research is the use of pervious concrete in the construction of transport infrastructure. The objective of the paper is to justify the use of pervious concrete in the construction of transport infrastructure by analyzing previous international experience and lab tests of the corresponding concrete samples. Research methods included a analysis of the international and domestic literature, the evaluation of the experience in the use of the pervious concrete, and laboratory tests of the corresponding concrete samples. A review of the world experience connected with research of pervious (draining) concrete, installation and operation of layers of aerodrome surface made of it, proved their technical and economic relevance and effectiveness of their application. Pervious concrete is a material with high open porosity, which provides good sound-absorbing properties and drainage ability together with roughness, smoothness, and transverse friction. These are advantages of pervious concrete pavements, according to foreign studies: a rapid removal of water from the surface of the pavements in case of rain and improved drainage of road and airfield pavements reduce the risk of aquaplaning vehicles and increase traffic safety in rainy weather; increased and stable surface roughness; reduced level of noise provided by vehicles. The draining ability of the pavements makes it almost dry. It also has a high degree of sound absorption. The results of the article can be implemented in various technologies of construction and repair of transport infrastructure. The search for the optimal composition of pervious concrete for its further use in the technology of construction and repair of various objects is the main purpose of predictive assumptions about the development of the object of study.
