What is it...

Community, environmental and municipal relations are important for HMA producers and when they have and odor problem, they address it!
Roof Odor 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.
Roof Odor Solutions® is a patent-pending 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.
Finally, there's a cost-effective solution!
Asphalt Solutions, Inc. was recently awarded the 2004 NOVA Award from the Construction Innovation Forum (CIF) for innovative ideas and new technology in the construction industry. A.J. Ronyak, President and CEO of Asphalt Solutions, Inc. of Lichfield Park, Arizona accepted the NOVA Award on April 29th, in Dearborn, MI. The CIF is an international nonprofit organization that was formed in 1987 to recognize innovations in the construction industry that improve quality and efficiency, and reduce the cost of construction.
Asphalt Solutions, Inc. eliminates odors from several different materials, and one particular material is asphalt roofing. We feel that when our AS-Roofing Additive is added to hot mix at the manufacturer in liquid form, it becomes hassle-free for individual roofing contractors that would be mixing the solutions themselves. When added to liquid asphalt, it has no effect on changes from liquid-solid-liquid form. It would be more economical for refineries to add the solution to the mix prior to sale for the use of asphalt roofing.
Upon mixing with asphalt cement, it has the chemical properties to act as oxygen neutralizer to eliminate the fumes and smell of asphalt in all stages of production, mixing, and paving. When mixed with the hot asphalt, the active ingredient in AS Roofing additive will exhaust all oxygen available in the mix for its oxidation process. The hot asphalt then, lacks enough oxygen to undergo its own oxidation process which would normally result in fumes containing sulfur – the main cause of bad asphalt odor. The product was tested at the National Center for Asphalt Technology (NCAT). All tests confirmed that the AS Roofing Additive reduces asphalt fume emissions and eliminates its odor.
