ROAD PAVEMENT Russian patent published in 1998 - IPC

FIELD: construction engineering. SUBSTANCE: this relates to pavement of motor roads, pedestrian crossings, flights of steps and other similar construction objects which are heated in winter period. Load-bearing layer of pavement is made up of separate cast plates, each having recess at side of base. Electric heater component is made in the form of flat panels, each being seated in recess of corresponding plate. Located between each heating panel and base is thermal screen which can be in the form of glass-wool mat with liners made of glass-reinforced plastic. Aforesaid arrangement ensures high repairability due to successive assembly and disassembly of components and at the same time improves efficiency in functioning as heating flux from electric heater can be controlled in value and direction. EFFECT: higher efficiency. 1 cl, 6 dwg
