Placing Grindings on a Roadway
For many years Benton County Public Works has recycled construction materials from other sources such as ODOT, City, and County roadways. Materials such as crushed concrete, asphalt grindings, and crushed aggregate can be reused to add structure to existing roadways or as base material for new roadways or surfacing. The County uses asphaltic grindings with a surface treatment where possible, in place of more expensive Hot Mix Asphaltic Concrete. This process is sustainable and results in economic savings for the public, with the trade off being a slightly rougher running surface than could be achieved using Asphalt. Below is a photo guide to the process the County uses to build a grinding and surface treatment roadway.
Roadway prior to grinding placement
Grinding a roadway prior to an overlay creates grindings which can be applied to another roadway.
The grindings are spread evenly across the road surface and compacted into place.
After the grindings are placed the road is chipsealed to cap the grindings.
A final fogseal protects the roadway from water penetration to help lengthen the life of the roadway.
Road markings are applied and the new roadway is complete

Information is also available on the Adopt-a-Road Program.
Roadside herbicide application starts April 1, and continues until approximately November 1.
The Road Maintenance Division of Public Works consists of three major programs: the Surface/Sign/Traffic Marking Program, the Vegetation Program and the Bridge/Drainage Program.
