AS Additive
by Asphalt Solutions

Community, environmental and municipal relations are important for HMA
producers and when they have an odor problem, they address it!

Asphalt Solutions has developed its new liquid odor-reducing additive that, when mixed with asphalt cement (AC), greatly reduces or eliminates the smell associated with asphalt.

Asphalt Solutions is a patented product whose chemical properties act as an oxygen scavenger with the asphalt to provide an end-to-end solution for asphalt odor: from holding tank to paver. At less than 4 cents per ton of hot mix asphalt (HMA), the additive is an economical answer to improving the environment for workers and neighbors of hot mix facilities.

Don't Mask... Suppress!

Asphalt Solutions comes in cherry or pine scent, but is much more than a mask for asphalt's petroleum odor. The suppressant actually acts as an oxygen scanvenger that significantly retards the release of compounds that are responsible for characteristic asphalt smell. The cost runs about 3-7 cents per ton of mix.

The additive, which is introduced into the asphalt binder at a rate of 1 gallon (3.8 L) to 12,000 gallons (45,424 L) of liquid AC, offers HMA companies and their neighbors the prospect of an improved environment for industry operations. The odor reducer can be added to a drum or batch plant, and comes in a cherry or pine scent. Since the additive is mixed right in with the liquid asphalt, you take care of the odors at the plant's exhaust stack and AC tanks, the solo's load-out, in the haul trucks, and at the back of the paver.

It's a true end-to-end solution for asphalt odor. The odor suppressant not only works with hot-mix asphalt, but cold mix and medium cure asphalt as well. Additionally, as HMA operations mill-off existing asphalt during recycling, asphalt originally treated with Asphalt Solutions have no odor during repaving operations.
