Asphalum powder use in asphalt crack sealer

Crack sealer produced by blend of bitumen with SBS, asphaltum, rubber process oil, crumb rubber in special temperature and pressure and using as sealing cracks and joints for the asphalt pavement and parking also cement pavement.

Asphalt sealer

It is use to seal expansion and longitudinal and transverse crack and construction joints between concrete and asphaltic shoulder. asphaltum is one of the most environmental friendly products to repair and seal the asphalt.asphaltum joint sealer and crack sealer is widely used in the world.

Roof seal additive

The preferred embodiment of the invention employs a roofing adhesive or cement for filling the parking lot crack, either asphalt or concrete after it has been thoroughly cleaned either with air or water. The adhesive is preferably a modified bitumen rubber asphalt normally used for bonding roofing materials.

Instead of ripping up an entire paved surface, various less expensive methods have been employed to repair cracks that may develop in these surfaces. One known process is to fill the cracks with an asphalt sealer.

While this often serves to fill the cracks at least temporarily, the utilization of current asphalt sealers to repair cracks suffers from some significant disadvantages.

Initially, Asphaltum asphalt sealers are susceptible to melting when subjected to high temperatures, which results in the sealer flowing away from a crack filling position. For example, when the asphalt sealer heats up, it becomes softer and can be squeezed, such as by a vehicle passing there over, so that it no longer properly fills the crack.

Asphalt crack filler

Additionally, because of their composition, current sealers can be slippery, which is undesirable. As existing asphalt sealers have very limited durability when serving to fill cracks, if the sealer no longer serves to fill the crack, additional crack repair services are required.

Accordingly, existing crack repair methods and systems are costly, both in terms of material and labor.

In some instances where the crack is deep enough, a grout material, such as a mortar or cement, is used to assist in filling these cracks. In these instances, the grout material is placed in the crack and allowed to harden.

Surface sealer

Thereafter, the asphalt sealer is placed in the crack over top of the grout material to completely fill the crack and level out the paved surface. This can also create durability issues in that existing grout fillers that are used in crack repair applications often have significant shrinkage issues.

Thus, while an asphalt sealer used to help fill a crack may initially be level with the surface being repaired, when the grout material shrinks, the asphalt sealer will drop into the crack as the level of the grout material recedes.

The asphalt sealer thus is no longer flush with the upper paved surface and often falls into the crack itself. In an effort to address some of these deficiencies, aggregates such as sand or limestone, were added to the asphalt sealer to provide it with more substance.

Advantage of asphaltum in crack sealing

However, these efforts were unsuccessful as these aggregates would release from the sealer, such as when contacted, and they would therefore eventually fail.

Thus, while they provided some increased durability, they ultimately suffer from the same disadvantages as asphalt sealers without an aggregate.

Crack seal system

It would therefore be advantageous to provide an improved asphalt sealer for paved surfaces that overcomes these disadvantages. It would also be advantageous to provide an improved crack repair system that overcomes the failings with current systems.
