Abstract
An apparatus which monitors and controls the mass flow rates of two or more fuels and air is connected to a burner of a conventional asphalt drum mixer. Several fuels are combined and ignited to produce predictable burner temperatures. In this manner, fuels which ordinarily burn inefficiently can be used in conjunction with other more combustible fuels to produce hot mix asphalt. The regulation of the total fuel to air ratio results in controlled combustion which reduces overheating of the asphalt.
