ABSTRACT:
An asphalt pavement heating device, for use with an asphalt pavement recycling or repair apparatus which uses heaters to warm the asphalt to a pliable form thereby facilitating the recycling or repair process, wherein a pressurized combustible gaseous mixture of fuel and air is burned in a non-oxidizing blue hot flame which is impinging the pavement surface, said flame being formed in a firebox which is suspended on the front and/or underneath the carriage of the apparatus over the heated surface, said firebox having flexible or "sealing curtain type" side walls which drape to the surface thereby excluding the entrance of ambient air, said device being characterized by its capabilities to rapidly heat asphalt concrete pavement and its smokeless exhaust.
