Observations/Finding

As requested, our AS Engerineering and Consulting (ASEC) representative visited the site for the purpose of providing quality control inspection and testing services, visual observation techniques were employed to assure compliance with project drawing/specifications, applicable codes, and materials submittals. The following observations were observed on site this day:

Contractor continued to work on Lot #53 and Lot #54.  Compaction was performed using a sheeps-foot roller.

Density testing was performed using a Troxler nuclear gauge (#3430, serial #85759). 

Density test results indicate that the compacted materials met project specifications of 90% of the maximum dry density obtained by the (Standard Proctor ASTM 698). See attached photos for approximate test locations.

Note: the moisture contents were found to measure higher than optimum.

Density testing result:

Moisture-Density Relationship (proctor) = 96.5 @ 22.2%

T1-elevation -1′ from finish grade, Yd 88.2, M%30.3, Compaction: 91.4%

T2-elevation -1′ from finish grade, Yd 90.7, M%30.5, Compaction: 93.4%
