Construction Testing and Documentation <br />F.1. Excavation <br />A variety of equipment is expected to be capable of performing earthwork and grading . An excavator or <br />backhoe with a smooth-lipped bucket is recommended for completing any excavations. This is intended <br />to limit disturbance to the supporting soils being left in place, while also producing a smooth working <br />surface. <br />F.2. Compaction <br />Fill should be placed in lifts adjusted to the compactor being used and the material being compacted. We <br />recommend limiting lifts to no more than 1 foot, assuming large, self-propelled or tow-behind compactors <br />are used. Thinner lifts should be used for lighter compaction equipment. <br />F.3. Cold Weather <br />If the earthwork occurs during freezing temperatures, good winter construction practices should be used. <br />No frozen fill should be used nor should structural filling take place on frozen ground. <br />F.4. Construction Phase Testing and Documentation <br />The bottom of all excavations, grading, and roadway subgrade should be evaluated and documented by <br />geotechnical personnel after the unsuitable materials are removed and before placement of any fill or <br />pavement. Samples of any fill materials and/or alternative gradations of materials proposed for use <br />should be submitted for approval before use. The City may wish to have, or may be obligated to have <br />tests performed regarding the other various paving components. Specification of such requirements is <br />normally the responsibility of the City and their design consultant. <br />G.
