  • Patent number: 5895171
    Abstract: A process for heating an asphalt surface and an apparatus therefor. The process comprises the steps of: igniting in a burner (30) a combustible mixture comprised of a fuel (50) and oxygen (60) to produce a hot gas; and feeding the hot gas to an enclosure having a radiative face (200) disposed above the asphalt surface (280). The asphalt surface heating apparatus comprises a hot gas producing burner (30) and an enclosure (25) comprising an inlet (120) for receiving hot gas from the burner and a radiative face (200) having a plurality of apertures. The apertures in the radiative face are of a dimension such that the hot gas: (i) heats the radiative face to provide radiation heat transfer to the asphalt surface; and (ii) passes through the apertures to provide convection heat transfer to the asphalt surface.

  • Patent number: 5653552
    Abstract: A process for continuously heating an asphalt surface is described. The process comprises moving a heater over the asphalt surface in successive forward and backward directions. The forward stroke of the heater is effected over a second distance and the backward stroke of the heater is effected over a first distance. The ratio of the second distance to the first distance is in the range of from about 0.10 to about 0.90. Preferably, the heater comprises at least two independent heaters arranged in series.
