Field Observations and Comments
Observed the Hydration and compaction effort of native soil structural fill with excavation areas A and B,(Please see
the attached map for locations). Centerline Construction used a bulldozer mounted sOil-ripper bar to np the first 11ft
(approximately 1-2 feet thIck) of native soil fill above subgrade Water was applied to the surface of this 11ft from
Ambleside Drive with a side-spraying water truck.
Performed field nuclear mOisture-density test on the first lift of native soil fill Based on the AASHTO T-99 theoretical
""'axlmum dry denSity and optimum mOisture for this matenal, this 11ft IS unacceptable at this tIme In conducting three
,Jloratory test pitS within excavation A, It was revealed that the subgrade had been npped up by the hydration effort
applied to the first 11ft. The mixing of material Into the first lift made achieving a uniform above optimum moisture
condition difficult. In discussing this Situation with Mr. Glenn Ling (Project Engineer), Troy Hull (PSI), and Mike
Kirkpatrick (Foreman, Centerline Construction) it was deCided that a shallow ripping and application of two full water
trucks of water to this lift would be followed by moisture-density testing again on Monday 10/11/99.
