Abstract

Disclosed are a method and a system for processing an asphalt pavement road for recycling purposes. The method includes steps of treating pieces of reclaimed asphalt pavement to form crushed material blocks; sorting the crushed material blocks based on size; selecting crushed material blocks having a predetermined maximum diameter; and compressing the selected crushed material blocks to form a briquette.

Claims

1. A method for processing an asphalt pavement road for recycling purposes, the method comprising steps of:

treating pieces of reclaimed asphalt pavement by accelerating the pieces of the reclaimed asphalt pavement with centrifugal force and making the pieces to impact a wall and each other, to form crushed material blocks;

sorting the crushed material blocks based on size;

selecting crushed material blocks having a predetermined maximum diameter; and

compressing the selected crushed material blocks to form a briquette.

3. A method according to claim 1, wherein the predetermined maximum diameter is 3 mm.

4. A method according to claim 1, wherein a circumferential speed is 20-100 m/s.

5. A method according to claim 1, wherein a compression force is 10-70 kN/cm.

6. A method according to claim 1, wherein the compression is carried out with a briquette compressing machine.

7. A method according to claim 1, wherein the crushed material blocks comprise rock and bitumen.

12. Use of briquettes obtainable by a method of claim 1 for making asphalt concrete, wherein the briquettes are added in an asphalt mixing process.

13. Use according to claim 12, wherein the amount of briquettes is 1-95%, as replacement or with untreated reclaimed asphalt pavement.

2. (canceled)

8. A system for processing an asphalt pavement road for recycling purposes, the system comprising:

an impactor machine for treating pieces of reclaimed asphalt pavement by accelerating the pieces of the reclaimed asphalt pavement with centrifugal force and making the pieces to impact a wall and each other, to form crushed material blocks;

a sieve for sorting the crushed material blocks; and

a compressor for compressing briquettes from the crushed material blocks.

9. A system according to claim 8, wherein the impactor machine is a vertical shaft impact crusher.

10. A system according to claim 8, wherein the sieve is arranged to sort and feed a predetermined maximum diameter range of crushed material blocks to the compressor.

11. A system according to claim 8, wherein the compressor is a briquette compressor.
