SECTION 1: 9.08.03 Excavations to be Restored. All material excavated for the street cut shall be removed and disposed of by the person, firm, or corporation performing said excavation. All excavations shall be restored with flowable fill to within 2" of the surrounding bituminous riding surface.
* The mix design for the flowable fill will be prepared by the Applicant. The mixture will be proportioned to produce a flowable mixture without segregation, material for one cubic yard, absolute volume, shall be as follows:
Cement - 80 - 100 lbs.
Fly Ash - 220 - 300 lbs.

The cylinder will then be pulled straight up and the flow will be measured by the approximate diameter of the mixture.
