发明名称 Asphalt imprinting apparatus
摘要 An apparatus for forming a pattern on the surface of asphalt comprising an endless belt having a surface formed of an elastic material and having a pattern in a form corresponding to a pattern to be impressed into the asphalt. The apparatus includes a belt pressing device, which may be in the form of a weighted roller or plate, for pressing the belt into the asphalt; and a pair of rollers spaced from either side of the belt pressing device, and at a higher elevation with respect to the asphalt surface to provide controlled lifting of the belt from the pressed asphalt. The belt is formed of an elastic material which has little compressibility, so that when pressed down by the belt pressing device, it spreads laterally outward to form pattern elements that are wider than when pressure is released, to provide clean separation from the asphalt surface.
