Abstract:An experiminetal application of NovaChip® was evaluated on a section of SR-17 through the city of Soap Lake, Washington. NovaChip® was investigated as a possible substitute for Hot Mix Asphalt (HMA) Class G that is normally specified through cities on routes that only warrant a bituminous surface treatment. The NovaChip® was placed in the summer of 2001. Pavement condition survey results and visual observations revealed that the NovaChip® was effective in reducing both the frequency and severity of cracking. Ride quality has remained constant throughout the six year evaluation period and wear/rutting has been minimal. Life cycle cost analysis showed that NovaChip® is comparable to HMA Class G when analyzed on a total project cost basis, but not competitive when only the cost of the overlay is considered.
