Density testing was performed using a Troxler nuclear gauge (#3430, serial #29588).

Density testing result:

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

T1-elevation -9′ from top of keyway P-2, Yd 102.4, M%25.4, Compaction: 102.9%

T2-elevation -9′ from top of keyway P-2, Yd 104, M%23.1, Compaction: 104.5%

T3-elevation -9′ from top of keyway P-2, Yd 102.5, M%24.4, Compaction: 103%

T4-elevation -8.5′ from top of keyway P-2, Yd 102.1, M%25, Compaction: 102.6%
