NovaChip: SR-17, City of Soap Lake, MP 75.44 to MP 76.15

Description: An experimental 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 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.
