Recycled asphalt pavement plant cleaning

Benefits of RAP Plant Cleaning

1. Faster and more effective than mechanical cleaning.
2. Less costly than mechanical cleaning.
3. Reduced operational disruption.
4. Safer than mechanical cleaning.
5. Reduced dust pollution problems.
6. Less risk of damage to machinery.

How is it done?

 Most asphalt recycling plants incorporate a hot recycling drum system.

This is a large rotating heated drum that breaks down recovered asphalt and mixes it with new aggregate to create the new RAP product. These hot recycling drums need to be regularly cleaned as part of planned maintenance to ensure they are working efficiently.

Hydroblast carries out this task using its remote high pressure water jetting tank cleaning system.

The water jetting equipment is set up inside the recycling drum. It can then be controlled remotely by a Hydroblast water jetting operative.

A rotating nozzle delivers high pressure water that removes bitumen and stone stuck to the sides of the RAP drum. The nozzle is designed to ensure all surfaces inside the RAP recycling drum system are jetted and cleaned.

Reduced pollution

Water jetting reduces pollution and health risks because it causes very low dust emissions. All smaller residue particles are suspended in the water jetting water which contained in a bunded area.

This water can then be filtered on site, to remove particulate material, then transported off site, if necessary, for safe disposal.

Recycled Asphalt Pavement and sustainability

Recycled Asphalt Pavement (RAP) is asphalt that has been recovered from roads and pavements and put through a recycling process, combining it with fresh aggregates, so it can be reused.

Using more RAP in road repairs and new road construction is quickly becoming an urgent priority as governments across Europe look for ways to meet their CO₂ reduction targets to tackle global warming.

Using more RAP reduce CO₂ levels and is more sustainable because it:

• Reduces the amount of material that needs to be quarried.
• Uses less energy than the process to create new asphalt.
• Reduces road stone transport costs.
• Reuses material that would otherwise be sent to landfill.
