Clackamas Community College, Douglas Loop Reconstruction, Oregon City, OR

With almost no structural base under the existing road, Douglas Loop had become cracked and worn, and exceed its useful life. A phased replacement was necessary. For the northern-end segment, a modified version of Full Depth Reclamation (FDR) was utilized, which required less haul off and a lower quantity of soil and rock material for the base.

Replacement of the NE and NW quadrants was completed in two phases to allow continued access to the campus. Work was completed over the summer in time for the start of school in the fall. In total, 3,478-LF of roadway was replaced in this phase of development.

The Southern portions of the loop road were replaced in phases as well, in conjunction with other facility updates and campus improvements. The replacement was part of the College’s bond program, with the new loop road now having a 40-year design life. The entire loop included 7,128 LF.
