Warren County pavement
Warren County, just South of Cincinnati, is the second fastest growing county in the state. The Long Spurling Road (County Road 171) located in the southeastern part of the county in Harlan Township was chosen by the Warren County Engineer's Office for FDR construction between SR132 and the north driveway to the LM Animal Products Plant.

The failing pavement was 0.4 miles in length, 20 to 21 feet in width with minimal shoulders and had a 2-inch asphalt layer on top of 4 to 6 inches of chipsealed pavement.

The pavement sampling and design was carried out by EDP Consultants under the supervision of OSU. Two sections were constructed as follows:

• 4-percent lime with 6-percent fly ash, 12-inch stabilization depth (0.32 mile)
• 5-inch mill and fill (0.08 mile)

The FDR rehabilitation of the Long Spurling Road was completed in five phases. Beginning in July, Strawser Paving milled and removed 4 inches of the existing pavement asphalt surface.

In the second phase, Base Construction pre-pulverized the remaining pavement materials to a depth of 12 inches. The third phase involved treating the pulverized pavement materials with lime at an application rate of 4 percent and allowing the material to mellow for a 24-hour period.
