Abstract

A asphalt pavement recycling device comprising a base frame hingedly secured to a platform, a rotatable drum unit rotatably secured to the base frame, the drum unit having a drum opening and a drum rear, a hopper assembly hingedly secured to the base frame, a burner assembly hingedly secured to the base frame wherein the burner is used to heat the materials which are to be recycled/processed, a fuel source, a plurality of right-handed flights secured within the rotatable drum unit, a plurality of left-handed flights secured within the rotatable drum unit, a plurality of gator plates secured within the rotatable drum unit, a hydraulic unit secured to the device and operationally associated with the base frame, the rotatable drum unit, the hopper assembly and the burner and a control station operationally associated with the hydraulic unit, the base frame, the rotatable drum unit, the hopper assembly and the burner.

Claims (66)

1. A asphalt pavement recycling device comprising:

a base frame hingedly secured to a platform;

a rotatable drum unit rotatably secured to the base frame, the drum unit having a drum opening and a drum rear;

a hopper assembly hingedly secured to the base frame wherein the hopper assembly can be pivoted to engage the drum opening, or pivoted to disengage the drum opening;

a burner assembly hingedly secured to the base frame wherein the burner assembly can be pivoted to engage the drum opening or pivoted to disengage the drum opening,

wherein the burner assembly is used to heat the materials which are to be recycled/processed;

a fuel source;

a plurality of right-handed flights secured within the rotatable drum unit;

a plurality of left-handed flights secured within the rotatable drum unit;

a plurality of gator plates secured within the rotatable drum unit;

wherein the flights and gator plates are operable in the heating, mixing, separating and granularizing the asphalt material to be recycled/processed; and

wherein the flights and gator plates are configured to ensure that the asphalt material does not come into contact with a flame produced by the burner assembly;

a hydraulic unit secured to the device and operationally associated with the base frame, the rotatable drum unit, the hopper assembly and the burner assembly; and

a control station operationally associated with the hydraulic unit, the base frame, the rotatable drum unit, the hopper assembly and the burner assembly.

2. The asphalt pavement recycling device of claim 1 wherein the burner assembly is secured adjacent to the drum opening of the rotatable drum unit and directs heat into the top ⅓ of the rotatable drum unit.

3. The asphalt pavement recycling device of claim 1 wherein the platform is a multi-axel trailer which can be towed behind a vehicle.

4. The asphalt pavement recycling device of claim 1 wherein the platform is a stationary platform.

5. The asphalt pavement recycling device of claim 1 wherein:

the plurality of right-handed flights are secured to an inner surface of the rotatable drum unit;

the plurality of left-handed flights are secured to the inner surface of the rotatable drum unit; and

the plurality of gator plates are secured to the inner surface of the rotatable drum unit.

6. The asphalt pavement recycling device of claim 4 wherein:

the right-handed flights are secured within a front-third inside the rotatable drum unit adjacent to the drum opening;

the left-handed flights are secured within a rear-third inside the rotatable drum unit adjacent to the drum rear; and

the gator plates are secured within a middle-third inside the rotatable drum unit located between the front-third and the rear-third.

7. The asphalt pavement recycling device of claim 1 wherein the device can process asphalt material selected from the group consisting of: recycled asphalt pavement millings, virgin aggregate mix and combinations thereof.

8. The asphalt payment recycling device of claim 1 wherein the device can process an amount of recycled asphalt pavement millings with a combination of 80% virgin liquid asphalt cement, 11% crumb rubber and 9% softeners to produce rejuvenated asphalt concrete.

9. A method for recycling asphalt, said method comprising the steps of:

providing a asphalt pavement recycling device comprising:

a base frame hingedly secured to a platform;

a rotatable drum unit rotatably secured to the base frame, the drum unit having a drum opening and a drum rear;

a hopper assembly hingedly secured to the base frame wherein the hopper assembly can be pivoted to engage the drum opening, or pivoted to disengage the drum opening;

a burner assembly hingedly secured to the base frame wherein the burner assembly can be pivoted to engage the drum opening or pivoted to disengage the drum opening,

wherein the burner assembly is used to heat the materials which are to be recycled/processed;

a fuel source;

a plurality of right-handed flights secured within the rotatable drum unit;

a plurality of left-handed flights secured within the rotatable drum unit;

a plurality of gator plates secured within the rotatable drum unit;

wherein the flights and gator plates are operable in the heating, mixing, separating and granularizing the asphalt material to be recycled/processed; and

wherein the flights and gator plates are configured to ensure that the asphalt material does not come into contact with a flame produced by the burner assembly;

a hydraulic unit secured to the device and operationally associated with the base frame, the rotatable drum unit, the hopper assembly and the burner assembly; and

a control station operationally associated with the hydraulic unit, the base frame, the rotatable drum unit, the hopper assembly and the burner assembly;

pivoting the hopper assembly to engage the drum opening;

receiving asphalt material through the hopper assembly, through the drum opening and into the rotatable drum unit;

pivoting the burner assembly to engage the drum opening;

igniting the burner assembly to heat the asphalt material causing the asphalt material to soften and dehydrate;

rotating the rotatable drum unit to tumble and granularize the asphalt material;

adding a rejuvenate material and mixing the rejuvenate material with the asphalt material;

heating and rotating the asphalt material for a period of time to a desired temperature and consistency resulting in a recycled/rejuvenated material which is ready to be used;

pivoting the burner assembly away to disengage from the drum opening;

pivoting the base frame and the rotatable drum unit to raise the rear of the drum unit and remove the recycled/rejuvenated material;

placing the recycled/rejuvenated material in a desired location; and

compacting the recycled/rejuvenated material resulting in asphalt cement.

10. The method of claim 9 wherein the burner assembly is secured adjacent to the drum opening of the rotatable drum unit and directs heat into the top ⅓ of the rotatable drum unit.

11. The method of claim 9 wherein the platform is a multi-axel trailer which can be towed behind a vehicle.

12. The method of claim 9 wherein the platform is a stationary platform.

13. The method of claim 9 wherein:

the plurality of right-handed flights are secured to an inner surface of the rotatable drum unit;

the plurality of left-handed flights are secured to the inner surface of the rotatable drum unit; and

the plurality of gator plates are secured to the inner surface of the rotatable drum unit.

14. The method of claim 13 wherein:

the right-handed flights are secured within a front-third inside the rotatable drum unit adjacent to the drum opening;

the left-handed flights are secured within a rear-third inside the rotatable drum unit adjacent to the drum rear; and

the gator plates are secured within a middle-third inside the rotatable drum unit located between the front-third and the rear-third.

15. The method of claim 9 wherein the device can process asphalt material selected from the group consisting of: recycled asphalt pavement millings, virgin aggregate mix and combinations thereof.

16. The method of claim 9 wherein the device can process an amount of recycled asphalt pavement millings with a combination of 80% virgin liquid asphalt cement, 11% crumb rubber and 9% softeners to produce rejuvenated asphalt concrete.
