5. Concrete + Asphalt = Degradation

6. Today we will discuss the different types of concrete vs.
asphalt damage and offer suggestions for solving those
problems.
The three most common locations for adjacent asphalt
and concrete breakdown are bridges, driveways and
parking lots.

7. To begin repairing damage or filling joints between
concrete and asphalt you must decide what color you
want your final repair to be.
Black
• FloMix
• PolyFlexDS Black
Gray
• FlexSet
• Concrete Welder Gray
• PolyFlexDS Gray

8. To Begin Your Repair
Make sure your repair is not on a slope of more than 20°

9. Preparing Your Repair
• Cracks under 3/8 inch should be widened to create a reservoir for the
material to penetrate.
• Clean joints with a diamond blade and a shop vac
• Use 4-inch tuck point grinder to clean uneven edges

10. Preparing Your Repair
Once clean, you can pre-fill with sand, keeping within ½
inch from the surface and sweep away excess sand.

11. Tip
Widening the top of the crack will allow for better flow

12. Preparing Your Pavement
Cracks and joints must be clean and dry. Sweep or blow out the cracks.

13. Preparing Your Pavement
• If there is water present, use a heat lance or a propane torch to dry the
pavement.
• Do not overheat the pavement as this can cause structural damage.
• If you have missed some of the moisture, the material will bubble. If this
happens, we recommend scraping the surface and adding another layer of
polyurethane.

14. Bridges
Asphalt and Concrete contact coupled with bridge expansion and contraction
causes the asphalt to curl, creating a bump at the approach and departure of the
bridge.
• Grind the asphalt lip
• Clean the surface and crack
• Apply a layer of FloMix, a flexible material that will allow for expansion and
contraction

15. Driveways
• Cracks should be filled from the bottom up if there is a slope
• Pre-place sand
• The grade should be 20 ° or less so that material will not flow too
quickly or too far.

16. Parking Lots
If the damage is more on the asphalt, fill all small cracks off of the joint with
PolyFlexDS Black mixed with sand first. If the repair is on the concrete side, use
PolyFlexDS Gray to fill the cracks first. Next, if the joint is larger than ¾ of an
inch, use FloMix to repair the damage.

17. Concrete Welder Gray
• Used for cracks in concrete slabs
• Can be used indoors or outside in warehouses, parking lots, sidewalks,
playgrounds, walkways, loading docks, driveways and more.

18. PolyFlexDS Gray
• Used to repair expansion joints or control joints on highways, bridges,
runways, patios, warehouses, parking lots, sidewalks, playgrounds,
walkways, loading docks, driveways and more.
• Also used for utility cuts.

19. PolyFlexDS Black
• For use in asphalt cracks on
highways, bridges, runways, patios, warehouses, parking
lots, sidewalks, playgrounds, walkways, loading docks, driveways and more
• Can be used in utility cuts
• Ideal between concrete and asphalt joints
