what is novachip
What is NovaChip
  • Ultra-thin polymer modified asphalt

surface treatment.

  • Combines open graded hot mix asphalt

with emulsified asphalt polymer-modified

membrane.

features benefits
Features & Benefits
  • Superior bond to the existing surface
  • Increases skid resistance, reduces noise
  • Ultra-thin application eliminates the need for utility adjustments.
  • Minimal traffic disruption, requires a single lane closure
  • Expected life cycle of up to ten years with crack sealing.
features benefits cont
Features & Benefits (cont..)
  • Does not affect overhead clearances on bridges, overpasses, signs, and other structures.
  • Reduces hydroplaning and reduces spray on wet roadways.
