Section 329IAC10-17-14. Optional drainage layer filter; construction and quality assurance/quality control requirements

   (a) The project engineer shall ensure that proper quality control and quality assurance testing, where applicable, is performed on the filter materials and that adequate results are obtained for the following tests, or equivalent tests, performed in accordance with section 17 of this rule:

(1) Grab elongation test.

(2) Grab tensile strength test.

(3) Puncture resistance test.

(4) Trapezoidal tear test.

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

(6) Abrasion or tumble test.

(7) Permitivity test.

(8) AOS test.

(9) Long term flow (clogging) test.

(10) Gradient ratio or hydraulic conductivity ratio (clogging) test.

(11) Any additional tests required by the commissioner.

  (b) The project engineer shall also ensure that the following criteria are addressed when determining the quality of the filter materials:

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

(2) The chemical compatibility of the geotextile.

(3) The polymer composition.

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

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

(6) pH resistance of the geotextile.

(7) Creep.

(8) Resistance to extreme temperatures.

(9) Resistance to bacteria.

(10) Resistance to burial deterioration.

(11) Other criteria, as determined by the commissioner.
