Abstract:In July & August, 2010, MaineDOT conducted experimental applications of NovaChip on 16 miles
of highway in western Maine. Novachip is a proprietary pavement process that applies an ultrathin,
gap-graded, hot mix wearing course over a polymer rich asphalt emulsion in one pass using a self-priming paver. The process quickly secures the NovaChip to the existing surface and allows for
minimal traffic delays. The polymer rich asphalt emulsion migrates into existing cracks to seal and
fill them. The asphalt emulsion bonds the NovaChip material to existing pavement. The placement
operation moves along quickly using a specialized paver that places material directly behind the
spray bar. A 10 ton steel roller follows the placement to seat the stone immediately after the
placement.
