on Ambleslde at lots 132/133, 134/135, 136/137, 138/139. Based on the newly available proctor curve for the
matenal of 97.5 Ibs/cu ft. @ 26 5% mOisture, thiS 11ft was unacceptable The measured dry densities were below the
Job specificatIOn of 95% of the theoretical maximum dry denSity and mOisture contents were above the theoretical
optimum moisture. Field density test results WIll be reported under separate cover.
Genterllne Construction foreman, Mike Kirkpatrick was informed of these results. He indicated that ripping thiS 11ft up
.nd hydrating it continuously until the correct mOisture condition could be achieved by tomorrow morning
