Observations/Finding

As requested, the site was visited by our AS Engineering and Consulting (ASEC) representative 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.

Compaction for the soils placed at the keyway continued today.

At the time of arrival, the contractor already placed soils and compacted to finished grade.

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

Density test results indicate that the compacted materials met the project requirement of 95% of the maximum dry density obtained by the (Standard Proctor ASTM 698). 

Density testing results:

P-1 Moisture-Density Relationship (proctor) = 97.3 pcf @ 23.7%

T1-elevation at finish grade@ keyway, Yd 100.4 M%26, Compaction: 103 %

T2-elevation at finish grade@ keyway, Yd 99.68 M%26.9, Compaction: 102.4%
