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
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.
