AMENDED CLAIMS

received by the International Bureau on 2 December 2013 (02.12.20 3).

1. A method of forming an improved asphalt sealer for repairing cracks in a paved surface, comprising:

providing an air cooled blast furnace sand;

providing a conventional asphalt sealer;

mixing said conventional asphalt sealer with approximately 40-55% by weight of said air cooled blast furnace sand;

whereby said resultant asphalt sealer has improved structural integrity.

2. (CANCELED)

3. (CANCELED)

4. The method of claim 1 , wherein said conventional asphalt sealer is mixed with approximately 48% by weight of said air cooled blast furnace sand.

5. The method of claim 1 , wherein the paved surface is an asphalt surface.

6. A method of repairing cracks in a paved surface, comprising:

identifying at least one crack in a paved surface to be repaired;

substantially filling said at least one crack with an asphalt sealer including approximately 40-55% by weight of an air cooled blast furnace sand; whereby said asphalt sealer can withstand large temperature deviations without failing.

7. (CANCELED)

8. (CANCELED)

9. The method of claim 6, wherein said asphalt sealer includes approximately 48% by weight of said air cooled blast furnace sand.

10. The method of claim 6, further comprising:

partially filing said crack with a grout material; and placing said asphalt sealer on said grout material.

1 1. The method of claim 10, wherein said grout material, includes class F fly ash in a range of approximately 0 to 30% by weight of said grout material and cement kiln dust in a range of approximately 50 to 90% by weight of said grout material.

12. The method of claim 6, wherein said paved surface is an asphalt surface.
