This project was the second phase of improvements to Eagle Creek Road (40040), which is classified as a Rural Minor Collector (FFC 07) located in Chelan County, Washington. It serves residential and school bus traffic, orchardists, outdoor enthusiasts, and logging traffic. The beginning of this project connects to the previous section at MP 3.30 and concludes at the end of the county road at MP 5.81.
The existing roadway structural condition fell below the level of minimal standards (ranging from 0 to 61, evaluated in 2012).
This project used the Full Depth Reclamation (FDR) with a cement treated base method with an HMA overlay to prevent further deterioration of the existing roadway and to maintain it at the least possible life cycle cost. In addition to the pavement rehabilitation, the project assessed mitigation measures for roadside hazards within the clear zone. FDR is not only an economically viable option; it is also a “green” option, since FDR recycles materials from the existing roadway and requires less hauling of materials.
