Nova Chip

The City of Sunset Hills Public Works Department will be applying a Nova Chip to Deane, Monica, Floralea, Lynstone, Windward Ridge, Homecrest, Tolstoi, and Spears in 2017. 

Nova Chip is a product the City has used successfully on numerous asphalt pavements, including West Watson from I-270 to Rott Road by the old Rott School, then on Rott Road from Pickle Hill to S. Lindbergh, including the entrance to the rear of Sunset Plaza, among other streets throughout the City.

2017 Nova Chip
A Nova Chip is a type of asphalt, typically more porous, but has a different application of the bonding agent that is immediately before the placement of the material. You can drive on it almost immediately after rolling it out. You'll note this material used by MoDOT on I-44 and I-270, north of I-44.
Here are some pictures of the process as applied in 2010 to Lombardy Lane in Sunset Hills:
