In progress: Krause and Jaster roads.
Whatโs that sign mean ?
When the final grading is finished, and the roadway is ready for paving; a prime oil is applied to both seal the surface of the sub-grade and create a better bond for the final chip seal pavement. The product we refer to as โprime oilโ is a water-based emulsion that dries quickly. When you encounter this on our county roads the product is safe for your vehicle to drive on slowly. If any of the prime oil transfers on your vehicle it is easily removed with soapy water.
