Nova Chip

PROJECT UPDATES AT BOTTOM OF PAGE

The City of Sunset Hills Public Works Department will be applying a Nova Chip to several streets to be determined in 2019. 

Nova Chip is a product the City has used successfully on numerous asphalt pavements, including the Sunset Manor neighborhood, connector routes like Rott Rd., (including the entrance to the rear of Sunset Plaza), Mentz Hill Rd. and other streets throughout the City.

These streets will be done in 2019

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.
