Recycling apparatus for particulate asphaltic concrete

In a drum for gradually heating particulate composition between an input and output end and having a port at said output end for recovering composition therefrom, the improvement comprising

• a retractable chute extendable into said port, having temperature sensing means for sensing the temperature of said composition in said drum in contact with said chute,
• drive means for selective extending and retracting said chute into said drum, and
• thermostat means for sensing a product temperature to be recovered from said drum whereby said drive means causes said chute to be extended into said drum to recover composition having a selected temperature.

Apparatus for recycling asphaltic concrete composition comprising:

• a rotatable elongated cylindrical drum having a first port at a first end thereof open to atmosphere through which hot gases of combustion and composition are introduced,
• a second port at a second end thereof for recovering heated composition therethrough, and closure means for maintaining said second port closed except to recover composition,
• a retractable recovery chute extending into said second port having temperature sensing means thereon for sensing the temperature of composition in said drum, and means for selectively inserting and retracting said chute into said drum, said drum having an interior length:diameter ratio of between about 2:1 to about 4:1, respectively.
