Due to cost considerations and the available budget for the project, three options used on SR 66 are not used on SR 87: AR Chip, Slurry Seal, and AR-ACFC. Another major difference between the SR 66 test sections and the SR 87 test sections is that the SR 87 test sections were placed on a 1-year old, 2-inch overlay while the SR 66 test sections were placed over an old chip seal.
