Abstract: An infrared asphalt heating and repair apparatus includes a converter having downward facing slits cut therein to provide enhanced durability over prior art ceramic blanket or metal ribbon style heaters. In embodiments, the slits are cut by a milling machine, which may be an automatic milling machine, a band saw, or a laser. Embodiments also provide for more uniform heating over prior art solutions, while largely preventing damaging and costly flame-through events. Because the heat is more uniform than that of the prior art, lower temperatures can be used to achieve similar results, thereby extending equipment life, lowering fuel costs, and reducing warm-up times.
