Hunterdon County expands road preservation program with micro surfacing set to begin Aug. 18
HUNTERDON COUNTY, N.J. — Hunterdon County is continuing its investment in long-term infrastructure savings through its pavement preservation program, which will expand this summer with new micro surfacing projects beginning in August 2025, officials said.
The initiative, launched in 2021 by the Hunterdon County Board of Commissioners, uses a cost-effective and environmentally friendly approach to extend the lifespan of existing roadways—reducing long-term repair costs while improving surface conditions for drivers.
“What began as a pilot project in Kingwood several years ago has grown into a countywide initiative,” said Commissioner Zach Rich. “More miles, less dollars, faster construction, and better for the environment—pavement preservation has been a home run for Hunterdon County’s roads.”
Hunterdon County primarily uses a method called slurry seal, which can extend the life of asphalt by six to ten years at a fraction of the cost of traditional hot-mix repaving. By delaying full road reconstruction, officials say the strategy frees up capital funding for other infrastructure needs.
In advance of the micro surfacing, crews will seal cracks and patch asphalt as needed. Work on several roads is scheduled to begin on or about Aug. 4, with micro surfacing expected to start on or about Aug. 18. Temporary traffic disruptions and limited on-street parking should be expected during the work period.
Roads scheduled for micro surfacing in 2025:
- County Route 523 – Dvoor Route 12 Circle to Stockton Borough
- County Route 641 – County Route 626 to High Bridge Borough
- County Route 626 – Overpass to I-78
- County Route 633 – Entire Length
Pavement preservation has shown a high return on investment by improving the average pavement condition while reducing the average cost per square yard, according to county officials.
