Core Pavement Base Number Station Thickness Thickness Remarks

1 58+00 Left 6 ¾” 6 ¾ - 12” Refusal on large rock, good granular material.

2 79+00 Right 5 ¾” 5 ¾ - 13” Good granular material in hole .

3 112+00 Left 7 ½” 7 ½ - 13 ½” Good granular material to 13 ½”, dense, hard hand auger continues in hole.

4 129+00 Right 4 ¾” 4 ¾ - 13 ½” Good granular material dense, hard auger continues in hole.

5 193+00 Right 8” 8 – 13” Good material, solid base continues, refusal on larger stone.

6 216+00 Left 7 ½” 7 ½ - 13” Good base, refusal @ 13” w/ large rock.

Pavement in pieces, delaminated.

7 226+00 Right 6 ¼” 6 ¼ - 13” Good base, very hard, difficult hand auger, very dense, granular material in hole, transition to small aggregate – hard.

8 265+00 Left 8 ¼” 8 ¼ - 13” Dense base, hard base, granular still in hole.

9 315+00 Right 7 ½” 7 ½ - 12” Hard coarse base, refusal @ 12” granular material in hole.

10 358+00 Left 7” 7 – 13” Hard base, difficult to auger. Hand auger difficult. Used core drill to get to 13”.

Larger stone encountered at 13”.

11 386+00 Right 6 ½” 6 ½ - 13” Very hard base, refusal @ 10 ½”, probe to 13”, dense granular still in hole.

12 439+00 Right 6 ¼” 6 ¼ - 12” Very hard base, refusal of auger @ 9 ½”.

Hard, dense base, probed to 12”.

Core Pavement Base Number Station Thickness Thickness Remarks

13 476+00 Left 8” 8 – 14” Hard base, dense, refusal @ 12”, probed to 14” granular material.

14 533+00 Right 5 ¾” 5 ¾ - 15” Dense Base, hard hand augering. Refusal @ 13”, probe to 15”.

15 557+00 Left 6 ¾” 6 ¾ - 15” Auger to 13” hard base. Probed to 15”, hard granular material.

16 588+00 Right 6 ½” 6 ½ - 13” Hard Base, refusal @ 11” on large aggregate probed to 13” with granular material.

17 630+00 Left 5 ¾” 5 ¾ - 14” Base not as dense, smaller aggregate. Hand auger to 14”, granular material in hole.

18 660+00 Right 5 ¼” 5 ¼ - 15” Delamination of top lift appears stripped.

Base not as dense, easier augering. Finer granular base, auger to 15”.

19 695+00 Left 6 ¾” 6 ¾ - 13” Hard base, difficult augering. Larger aggregate, refusal @ 11”, probed to 13”, solid dense material.

20 743+00 Right 7 ¼” 7 ¼ - 14” Stripped pavement @ 2 depths, cracks noted in core hole. Base not as dense, auger to 14”.

Not as large aggregate, granular material in hole.

21 839+00 Left 8 ¼” 8 ¼ - 14” Top lift debonded. Hard Base difficult augering, refusal on rock @ 12”, probed to 14”, solid granular material.
