Observations/Finding

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

The contractor continued work on the keyway.  Fill was placed and spread using a dozer.  Compaction was performed using a sheeps-foot roller.

Density testing was performed using the Standard Test Method for Density of soil in place by Drive-Cylinder (ASTM D 2937).

Test results indicated that the compacted material met project requirement of 95% of the maximum dry density obtained by the (Standard Proctor ASTM 698). See attached picture for approximate test locations.

Density testing result:

P-2 Moisture-Density Relationship (proctor) = 99.5@22.1%

T1-elevation -10.’ from the top of keyway, Yd 103.3, M%23.6, Compaction: 103.8%

T2-elevation -10.’ from the top of keyway, Yd 99.5, M%23.3, Compaction: 100%

T3-elevation -9.5.’ from the top of keyway, Yd 103.2, M%21.5, Compaction: 103.7%

T4-elevation -9.5.’ from the top of keyway, Yd 101.9, M%22.6, Compaction: 102.4%
