Abstract

The present invention relates to the field of recycling, in particular, to a method and apparatus for recycling asphalt pavement. The method comprises contacting the asphalt pavement with one three or more solvents (n-pentane, cyclohexane, and butanol) to form a mixture, subjecting the mixture to an elevated temperature of 50-100 ºC, and separating the mixture into a solid component and a liquid component.

Claims (6)

1. A method of isolating constituent materials of asphalt pavement, the method including the steps of: a. contacting the asphalt pavement with three or more solvents to form a mixture; b. subjecting the mixture to an elevated temperature of between about 50ºC and 100 ºC; and c. separating the mixture into a solid component and a liquid component, wherein the three or more solvents comprise n-pentane, cyclohexane and butanol, to thereby isolate the constituent materials of the asphalt pavement.
2. The method of claim 1, wherein the constituent materials is asphalt and/or aggregate material.
3. The method of claim 1 or 2, wherein the elevated temperature is between about 75ºC and about 95ºC.
4. The method of claim 3, wherein the elevated temperature is between about 85ºC and 95ºC.
5. The method of claim 4, wherein the elevated temperature is between 90ºC and 95ºC.
6. The method of any one of the preceding claims, wherein step b. occurs for greater than 10 minutes, greater than 20 minutes, greater than 40 minutes, greater than 90 minutes or greater than
