MICRO SURFACING EMULSIONS
The humble chip seal and other road surface treatments that use asphalt emulsions are being taken to new heights by a variety of modifiers that enhance performance, albeit at a higher price.
Thus polymer-modified asphalt emulsions can improve performance to the point that with the right design, they can challenge hot-mix asphalt as an overlay option for high-level, high-traffic pavements
Polymer modifiers are extremely common as binder modifiers because they enhance aggregate/binder bonding and other benefits. The tradeoff is a higher quality, typically about 40% over non-modified emulsions.
Polymer modifiers are taking the chip seal well beyond its classic application on low-volume roads. For example, polymer modification allows the use of emulsions in new, robust applications such as microsurfacing, ultrathin bonded wearing course,and macrosurfacing.
One of the most versatile tools in the road maintenance arsenal, Microsurfacing is a polymer-modified cold-mix paving system that can remedy a broad range of problems on today's streets,highways, and airfields. Microsurfacing has added capabilities, thanks to the use of high-quality, carefully monitored materials, including advanced polymers and other modern additives.
As usual our desire to move beyond the conventional products and constant endeavor to be the pioneers in the Industry had led to collaboration with flsamex(Europe} for manufacturing high quality Polymer Modified Bitumen Emulsions used for National Highways and Airport Runways.
