Utilizing a large dozer (DO), the contractor spread recently placed/stuckpiledhcrmed <br />imported soils from the Highway 9 widening site (bluish gray SILT to brownish gray silty SAND with few gravels) into an approximately .5.1' <br />loose lift and compacted the material via large vibratory roller. The compacted material was observed to be unyielding under the continue([ <br />wheel weight of truck/trailer assemblies. Further, the compacted soil was probed, with the full weight of the observer on a .5" diameter steel <br />f-probe, and proved fimt/unyielding with average pencimtions of I". A series of in place density tests were conducted to con Firm the spccif ed <br />minimum compaction (95% ASTM 1557). The contractor was notified of all density results listed below. The contractor noted that some areas <br />of fill near the cast end of the proposed disposal area appeared wet upon import. These areas, the contractor noted, would be further aerated to <br />allncar optimum moisture condition before being compacted.
