construction. SUBSTANCE: proposed process has the following stages: kindling of fuel mixture in burner to obtain hot gas, mixture consisting of fuel and oxygen, delivery of hot gas into chamber which is provided with perforated surface placed over asphalt coating. Asphalt coating heating device has burner to produce hot gas, chamber with inlet hole to take in hot gas from burner, and radiating surface with great number of holes. Sizes of holes in radiating surface are made to provided heating of radiating surface for creating radiating heat transfer to asphalt coating, with hot gas passing through holes and creating convective heat transfer to asphalt surface. EFFECT: provision of uniform and effective heating of asphalt coating. 10 cl, 3 dwg
