Abstract:
An apparatus for pyrolysis of a bituminous paving mix containing aggregate and a combustible asphalt binder, said apparatus comprising:an oven having a bottom wall, a top wall, and side walls defining a combustion chamber; a sample support provided within said combustion chamber for receiving and supporting a sample of the paving mix; an infrared heater mounted within said oven and arranged for emitting infrared radiation toward said sample support so as to heat the sample of paving mix to combustion by means of infrared radiation heat transfer; an air inlet positioned for admitting air into the combustion chamber; an outlet positioned for discharging combustion gases from the combustion chamber to thereby provide for the circulation of air and combustion gases through the combustion chamber; and a blower cooperating with said combustion chamber for causing air flow into the combustion chamber via said inlet and out of said combustion chamber via said outlet.
