§ 72-702. Density testing.

(a)

Certified testing laboratory. Density tests for determination of the specified backfill, base, etc., compaction shall be made by a certified testing laboratory approved by the CDE and at the expense of the permittee. Test locations shall be at random locations and shall be spaced not more than 300 feet apart where the trench cut is continuous, unless otherwise approved by the CDE. Tests shall be required for the first lift, second lift and the base. A copy of the laboratory report shall be submitted to the CDE.

(b)

Spacing of tests.

(1)

For each test section, a minimum of one test is required for the first lift (up to one foot above the utility). Testing for the second lift backfill under the traveled way shall be a minimum of one test at two-foot vertical intervals for each crossing.

(2)

Tests for second lift backfill in other areas will be at the discretion of the CDE.

(3)

A minimum of one density test for the base course for each 300 continuous feet of each road crossing shall be required.

(c)

Concrete compression. Concrete compressive strength tests may be required at the option of the CDE.

(d)

Unsatisfactory test results. If any test results are unsatisfactory, the permittee shall reexcavate and recompact the backfill at his/her expense until the desired compaction is obtained. Additional compaction tests shall be made to each side of an unsatisfactory test, as directed by the CDE, to determine the extent of reexcavation and recompaction necessary.
