Abstract
A melter and applicator (10) is shown for applying liquefied paving material to damaged pavement. The applicator (10) reduces the problems which occur due to the unintentional solidification of the paving material within the hose (74) of either the heated or unheated type. A cabinet (44) is provided which is selectively able to maintain the temperature of the unheated hose (74) during periods of non-use. In addition, a wand access port (100) is provided which allows either type of hose (74) to be run continuously, directing material back to a supply bin (26). In addition, a chimney (40) is provided which vents the by-products of combustion generated while melting the paving material. This chimney, (40) is fluidly coupled to the bin (26) which contains the paving material so that noxious fumes produced during the melting are drawn off.
