DRAINAGECONCRETEIN ROAD CONSTRUCTION

Abstract

This paper considers the use of highly permeable concrete, al-so known as drainage, porous, coarse-grained, moisture-permeable, permeable concrete, in road construction, which is a special type of concrete whose porosity is higher than most others. High permeability of water through the body of the concrete structure to the lower layers of the base is achieved due to interconnected pores and voids. Highly permeable concrete pavement is used to reduce local floods in ur-ban areas, acting as a sustainable drainage system. The permeability of permeable con-crete can be reduced during operation due to clogging of pores, this leads to a limitation of the service life of such a coating. The issues of studying the mechanism of clogging and ways to combat it remain open.
