In 2007 Aggregate Industries developed an innovative new product designed to use warm mix technology by incorporating Sasobit wax in their liquid asphalt binders that would enable the company to enter the pavement maintenance market, which primarily consists of products such as chip seal, micro-pavements, and slurry seals which typically do not yield any structural improvement to the existing paved roadway surface.

Thin Lift benefits

Aggregate Industries Thin Lift surfacing solution is a hot mix asphalt surfacing material that was developed in conjunction with a leading university specializing in asphalt technology research.

The product is capable of fulfilling the same applications as chip seal, micro-pavements or slurry seals but does so in a more cost-effective fashion.

In addition, the product can incorporate warm mix technology which affords it some specific benefits unique to this particular product. Those include:

• Minimal road preparation prior to installation
• Utilization of a polymer modified asphalt binder which ensures good performance at both low and high temperature conditions and greater rut resistance
• Quicker opening to traffic, which reduces public inconvenience
• Greater integrity then alternative maintenance products currently available as a result of the aggregate composition of the material
• The ability to cover greater roadway surface with less material, significantly reducing job costs
• Ability to incorporate higher percentages of Recycled Asphalt Pavement (RAP)
• Minimal smoke emissions from manufacturing
• Reduced emissions and energy costs

The product developed by Aggregate Industries serves as an extremely robust alternative to typical roadway maintenance products and applications where traditional HMA overlays may not be necessary. It is most effective on residential and secondary roadways where moderate to well traveled usage is customary.
