New Honeywell polymer additives for asphalt decrease paving energy costs and pollutant emissions
11 March 2013
Honeywell has introduced a line of additives for asphalt aimed at helping the paving industry decrease energy usage, reduce emissions and save money while helping meet demanding road specifications. The new Honeywell Titan additives for asphalt have been shown in real-life paving trials (subject to weather and paving practices) to reduce the fuel required to mix asphalt by 13% and harmful emissions generated by road paving by as much as 82%, while helping to minimize rutting. Depending on the asphalt’s composition, using Honeywell Titan can also reduce the amount of additive required by nearly 30%.
By adding small quantities of Honeywell Titan additives, asphalt flows as much as 60 to 80% more easily compared with asphalt modified with traditional technologies. Improved asphalt fluidity allows for temperature reduction during both the manufacturing and paving processes, so less energy is needed and costs are reduced for both asphalt manufacturers and road pavers. In addition, asphalt formulated with Honeywell Titan doesn’t require high shear mix equipment, making it easy to handle and use.
Decreased rutting could help roads last longer and decrease the amount of maintenance required.
Honeywell Titan’s unique properties have also been demonstrated in a paving trial with the Texas Department of Transportation to decrease fuel usage by 13%, and decrease the number of paving roller passes by one-third, which in turn reduces the time required to pave roads. Peer-reviewed data demonstrate that adding Honeywell Titan to asphalt can reduce paving-related emissions of sulfur dioxide by 82%, NOx by 43%, volatile organic compounds by 19%, and carbon dioxide by 18%.
Honeywell Titan additives for asphalt have low viscosities above their melting point and high heat resistance. They are available in a variety of product forms and packaging.
So... if these additives help the ashpalt to flow better at lower temperatures wouldn't those temperatures be easier to reach on a hot day with heavy traffic (like 30-wheeled trucks heading to the landfill that are typical in metro-Detroit)? If the answer is yes, then how would "rutting" be minimized? Besides, around here rutting is not the reason roads are replaced, first they bust apart from the high loads, excessive salt and freeze/thaw cycles getting into the cracks.
In higher traffic states with snowy seasons, an ashpalt that holds onto salt better would reduce the damage due to freezing and make for safer roads.

Reduced emissions and cost for an equivalent or better quality product is a win-win-win?
