Project Description

The 2023-2024 Arterial Grind & Overlays' will take place on:

  • Lincoln Road from North Division Street to North Standard Street
  • East Holland Avenue from North Colton Street to North Nevada Street

Grind and Overlay, also known as milling and resurfacing, is a four-step process widely used in road rehabilitation for its cost-effectiveness and minimal disruption compared to complete reconstruction. This method focuses on targeted repairs and improvements without extensive excavation or full roadway replacement.

The first step involves the removal or lowering of all manholes, surface storm-water, and sewer structures to protect them from damage during the grinding process.

In the second step, the top layer of the existing asphalt is ground down or milled to remove damaged or worn-out material. This milling process creates a smooth, even surface that provides a solid foundation for the new asphalt layer.

The third step involves raising and replacing the surface structures that were removed or lowered in the first step, ensuring they are aligned with the new road surface.

Finally, the fourth step is the application of a new layer of asphalt over the milled surface, effectively overlaying the old pavement. This new asphalt layer restores the road's structural integrity, improves its appearance, and enhances durability. By sealing off cracks and imperfections, the overlay provides a smooth, safe driving surface capable of withstanding traffic and weather conditions.

The Grind and Overlay method is favored for its ability to efficiently extend the lifespan of existing roadways while maintaining safety and aesthetics.
