What is hot pour crack filler?

Hot pour crack filler is a flexible, rubber-like product that is used to repair cracks in asphalt pavements. It starts out as a solid, rubber block or cube which is melted down in a special kettle. Once melted, the crack filler is applied over cracks in the asphalt pavement as a flat strip.

 

What is the difference between hot pour and cold crack fillers?

Hot-rubberized crack filler is melted and applied with black beauty sand broadcast on top while in liquid form, then it cools to a pliable, rubber-like consistency allowing it to expand and contract with the crack. Cold-putty crack fillers can be a water or asphalt based product that is applied to cracks in cold-putty form, and then dries to a solid. It is a much cheaper filler, but it does not perform nearly as well as the hot rubberized crack filler. It usually pops out by the first frost, therefore leaving cracks open for winter damage to occur. That is why both municipal and state roads only use hot rubberized crack filler, as well as commercial property owners.

 

Why isn't the hot pour crack filler completely hardened?

After it has been applied and allowed to cool, hot pour crack filler is supposed to remain flexible. If you press it with your finger it will flex. If you park on it with your car tires, it will temporarily retain the tread pattern. This is normal for this type of material.

 

How soon can pavement sealer be applied to hot pour crack filler?

Pavement sealer can be applied to hot pour crack filler almost immediately! Hot pour crack filler usually cools enough to apply sealcoating within 5 minutes of being applied to the ground.

 

Some of the hot pour crack filler pulled up! What should I do?

Hot pour crack filler can sometimes pull up as a result of parking directly on it with the hot tires of a car that has just come to rest after prolonged driving at highway speeds. The hot tires can re-heat the crack filler, which then re-cools, adhering to the tire. When the vehicle is later moved, a small portion of the hot pour crack filler pulls up and away with the tire. Although this is a rare occurrence, there is not much that can be done to prevent it except to attempt not to park directly on the hot pour crack filler while the tires of your vehicle are still hot.
