Increased Efficiency

 Asphaltica has patented a process to condition RAS and RAP, allowing time for osmotic reactions to take place inside a protected pellet.

Due to the hardness and the high temp temperature-viscosity curve, it is well known in the asphalt technical arena that ground untreated RAS and RAP does not combine with the virgin binder and therefore is not effective asphalt in the hot mix.

Asphaltica has patented a process to condition the RAS and RAP allowing time for the osmotic reactions to take place inside a protected pellet. This reaction ensures the softening of the highly oxidized bitumen allowing it to soften to a paving grade asphalt.

Along with the rut resistance of the fiberglass fibers in the ground shingles, the bitumen present in the shingles is a higher grade than what is often used in pavements, thereby improving the asphalt hotmix.

The #4 hard aggregates in the shingles are often needed in mix designs as well, to promote higher VMA.
