FIELD: construction.
SUBSTANCE: invention relates to construction, in particular to bridge construction and the construction of highways, and can be used to drain water from the structure of pavement and from the surface of the carriageway of roads, bridge structures, runways, flyovers, overpasses, tunnels and other similar structures. The device for drainage, containing flat and protruding elements, is made of a polymeric material having a transition temperature to a viscous-flow state above 200°C and a tensile modulus of at least 2500 MPa, is made in the form of a rectangle with longitudinal sides and end sides, with flat and the protruding elements are mated with each other, and the protruding elements are made trapezoidal and have inclined lateral and upper surfaces connecting them, and form trapezoidal channels connected to each other.
EFFECT: highways and bridge construction improvement.
