Abstract

A roller compacted concrete paving sealing method which includes the steps of paving a first area with roller compacted concrete paving, paving a second area with roller compacted concrete paving adjacent to the first paved area, forming a cold joint between the first area and the second area, rolling the cold joint, allowing the rolled cold joint to cure, milling the cold joint and removing any milled material, applying primer to the milled cold joint, filling the milled joint with hot poured filler and finishing the filled joint. The method is done with asphalt paving equipment and specialty milling and hot poured filler equipment.

Claims

1. A roller compacted concrete paving sealing method comprising the steps of

paving a first area with roller compacted concrete paving;

paving a second area with roller compacted concrete paving adjacent to the first paved area, forming a cold joint between the first area and the second area;

rolling the cold joint;

allowing the rolled cold joint to cure;

milling or sawing the cold joint and removing any milled material;

applying primer to the milled cold joint;

filling the milled joint with hot or cold poured filler; and

finishing the filled joint.

2. The method according to claim 1, wherein said paving is done with a high density double tamping bar asphalt paver.

3. The method according to claim 1, wherein adjacent paved areas shall be placed without time restrictions to any previously paved areas.

4. The method according to claim 1, wherein said rolling is done with a tandem type dual steel drum asphalt roller.

5. The method according to claim 1, wherein said rolling is done with a combination type roller with pneumatic tires and steel coated drums.

6. The method according to claim 1, wherein said rolling is done with a combination type roller with rubber coated drums.

7. The method according to claim 1, wherein a white pigmented curing compound and water are applied.

8. The method according to claim 1, wherein joints are thoroughly cleaned and blown out with compressed air after milling.

9. The method according to claim 1, wherein transverse contraction cuts are performed at regular intervals along the milled joint.

10. The method according to claim 8, wherein transverse contraction cuts are filled with an expansive sealant.

11. The method according to claim 1, wherein the formed joint is milled with a milling machine with a specially modified cutting head or a concrete saw.

12. The method according to claim 1, wherein the hot poured filler is a synthetic polymer modified resin containing fillers, sand and graded granite aggregates.

13. The method according to claim 1, said hot poured filler is heated with a polymer aggregate double jacketed boiling pot.

14. The method according to claim 1, wherein finishing is allowing the joint to be air-dried and scraped with a hot concrete scraper.
