Bitumen Truck Cleaning

The road surfacing industry is a massive business here in Australia.


 “Sprayed Seal” is often used in Road resurfacing and pavement refurbishing.

A sprayed seal is a thin layer of binder sprayed onto a pavement surface with a layer of aggregate incorporated and which is impervious to water. A Sprayed Seal is sometimes referred to as a “Spray Seal”, a “Bitumen Seal” or a “Chip Seal”.

The trucks and equipment used to apply the spray seal can, over time, become heavily contaminated with a build-up of bitumen spray which can be extremely difficult and messy to remove.

Dry Ice Blasting remove the hardened layers of bitumen without damaging the sensitive and nozzles and control lines.

Dry Ice Blasting offers a relatively fast and less hazardous method of cleaning which can achieve excellent results.

How Does Dry Ice Blasting Clean?

The Dry Ice Pellets are propelled at supersonic speed by compressed air. Upon impact, the Dry Ice creates a “micro-thermal shock” (caused by the extreme cold of the pellet @ -79.5° C), which breaks the bond between the coating and the substrate. The high-pressure air stream removes the dirt from the surface and the Dry Ice pellets vapourise (sublimate) before your eyes.
