Section 329IAC10-17-12. Protective cover component of the liner; construction and quality assurance/quality control requirements

   (a) The protective cover must be installed in a single lift with no compaction. Quality control and quality assurance testing on the protective cover must include the following tests conducted at the indicated frequencies during installation of the protective cover:

(1) Grain size distribution to the number 200 sieve must be performed for every one thousand five hundred (1,500) cubic yards of protective cover placed on the liner system.

(2) Any additional tests as specified in the construction plans or as determined by the commissioner to assure quality control and quality assurance.

  (b) If the geotextile described in section 11(b) of this rule is used as an alternative to the protective cover, the project engineer shall ensure the following:

(1) Proper quality control and quality assurance testing is performed on the geotextile, and adequate results are obtained for the following tests, where applicable, or equivalent tests, performed in accordance with section 17 of this rule:

(A) Grab elongation test.

(B) Grab tensile strength test.

(C) Puncture resistance test.

(D) Trapezoidal tear test.

(E) Ultraviolet (five hundred (500) hours) resistance test.

(F) Abrasion or tumble test.

(G) Other tests that may become necessary as determined by the commissioner to demonstrate the integrity of the geotextile.

(2) The following criteria are addressed when determining the quality of the geotextile:

(A) The nature of the fibers (i.e., continuous filament or stable fibers).

(B) The chemical compatibility of the geotextile.

(C) The polymer composition.

(D) The structure of the geotextile (i.e., woven or nonwoven).

(E) Thermal degradation and oxidation in extreme acidic conditions.

(F) pH resistance of the geotextile.

(G) Creep.

(H) Resistance to extreme temperatures.

(I) Resistance to bacteria.

(J) Resistance to burial deterioration.

(K) Other criteria that may become necessary as determined by the commissioner to determine the quality of the geotextile.
