SOUP Cold Asphalt Solutions

RAP based pothole repair and new road construction - FAQ

What is SOUP?

SOUP is a unique rejuvenating liquid to be mixed with recycled asphalt aggregates (RAP) to create a strong, inexpensive patching mixture

How much SOUP do I need?

SOUP is mixed with RAP at a ratio of approximately 1:50. To make 1kg of finished material, 97-99% RAP should be mixed thoroughly with 1-3% SOUP. The exact amount depends on the application, climate, type of RAP aggregates and their size

Can I use SOUP with normal aggregates?

No. SOUP is a rejuvenating agent that only reacts with RAP. Combinations of RAP + Aggregates + SOUP work, however RAP must be included

What is the recommended RAP aggregate size?

We recommend working with filtered RAP aggregates, not larger than 12mm. Larger aggregates could be used if the pothole is very deep.

Is the material workable under any climate?

Yes! When the stones are already mixed with SOUP, potholes can be fixed even while it’s raining or snowing. Pouring the cold asphalt mix into a water filled pothole simply displaces the liquids and patches the hole. With SOUP, potholes in Siberia, Russia were repaired under -30C; Just make sure the RAP is dry before mixing.

When can the road be re-opened for traffic?

Immediately! The pothole is ready for traffic immediately after patching.

Do I need to compact the patch?

Generally no. The passing cars will do the work for you; just make sure you use enough of the mix so it is just above the road surface to allow setting. However, if you wish to compact, this will only improve the quality of your patch and make it more even. The more compaction, the better the results.
