CHANNEL-DRAIN PREFABRICATED PAVEMENT OF AIRFIELD RUNWAYS, METHOD OF ITS HEATING AND SURFACE SIGNALLING ACCENT LIGHTING Russian patent published in 2013 - IPC E01C9/00 

FIELD: construction.

SUBSTANCE: pavement of airfield runways is laid in the upper tier with rectangular boards and comprises an inner storm water sewage network, which communicates with the working surface of the pavement via a grid of vertical drainage holes. The pavement is laid with single-layer arrangement of rectangular cellular boards with continuous channels inside them, where contours of surfaces are formed by a channelled bottom part with elements inclined relative to the working surface, flat side walls, which are vertical or truncated towards outer sides, and a ceiling of an arc section with parallel elements relative to the working surface of the board. The pavement is mounted in the cross section of the runway from different boards with serially increasing depth of channel installation from the axis of the runway to the sewage headers near its sides with formation of serially falling steps in direction of drain in joints between these profiles of channels in adjacent boards. The method for heating of walls of vertical drain holes of the pavement and signalling accent lighting of the runway surface through them consists in the fact that all cavities of the channel-drain system of the pavement from the sewage headers near the runway side to vertical drain holes are used for periodical pumping of air from heaters, and also for installation of glass fibre light guides from sources of light outside the limits of the runway to the ends of the glass fibres fixed inside the specified vertical holes in the pavement boards.

EFFECT: increased safety of air transport operation.
