714.02 Geocomposite Drain. Furnish a prefabricated geocomposite drain composed of a drainage core and a nonwoven geotextile that permits in-flow from both sides. Geocomposites that only permit in-flow from one side may only be used directly against a concrete surface. Furnish geotextile and drainage core manufactured from long chain synthetic polymers composed at least 95 percent by mass of polypropylene, polyester, polyamide, polyvinyl chloride, polyolefin, or polystyrene. Build the core up in thickness by columns, cones, nubs, cusps, meshes, stiff filaments, or other configurations. Fabricate the core in sheets, panels, or rolls of adequate strength to resist installation stresses and long-term loading conditions.

Property values, with the exception of fungi resistance, in these specifications represent MARV in the weakest principal direction (that is average test results of any roll in a lot sampled for conformance or quality assurance testing must meet or exceed the specified values).

Furnish a nonwoven encapsulating geotextile meeting requirements of Table 714-1. Firmly attach the encapsulating geotextile to the core at the manufacturing plant, so that folding, wrinkling, or other movement cannot occur during handling or after placement. Use a nonwater-soluble adhesive, heat sealing, or other methods recommended by the geotextile manufacturer. Do not use adhesive on areas of the geotextile where flow is intended to occur.

If heat sealing is used, do not weaken the geotextile below the required strength values. Extend the geotextile beyond the core length on all sides sufficiently to encapsulate the core and collector pipe.

714.04 Reinforcement Geotextile and Geogrid. Furnish reinforcement geotextile manufactured using long-chain, synthetic polymers, composed at least 95 percent by mass of polyolefins or polyesters. Form the geotextile, including selvedges, into a stable network such that the filaments or yarns retain their dimensional stability relative to each other.

Furnish reinforcement geogrid manufactured as a regular network of integrally-connected longitudinal and transverse polymer tensile elements with a geometry that permits significant mechanical interlock with the backfill. Provide geogrid composed of fibers or ribs that are at least 95 percent by mass polypropylene, polyethylene, or polyester. The geogrid structure must remain dimensionally stable under construction stresses and have a high resistance to damage during construction, to ultraviolet degradation, and to chemical and biological degradation encountered in the soil being reinforced.

Conform to Tables 714-5 and Table 714-6. Property values represent MARV (that is average test results of any roll in a lot sampled for conformance or quality assurance testing must meet or exceed the minimum specified values).

The nominal long-term strength (Tal) is based on:

Tal = Tult/RF where RF = RFID × RFCR × RFD.

RFID, RFCR, and RFD values must be substantiated by evaluation of independent test results by Highway

Innovative Technology Evaluation Center (HITEC), AASHTO National Transportation Product Evaluation

Program (NTPEP), or an equivalent third party report. Provide a copy of the report to the CO. Determine

RFID, RFCR, and RFD according to the following:

South Fork Road 40N26 Construction, AG-9AC7-S-15-0052 30 | P a g e

(a) RFID: Determine the reduction factor for installation damage from the results of full scale construction damage tests conducted according to ASTM D5818. Conduct the tests with a soil having the same maximum particle size, D50, and angularity as the soil to be used for construction. Tests using coarser soils (same or larger maximum particle size and D50) may be an acceptable substitution. The

CO will make the final determination as to whether the test data based on the substitute soil is acceptable. Interpolation of RFID will not be allowed, the results for the coarser soils will be used. The

Contractor may elect to perform a test using project specific fill, placement, and compaction techniques and equipment to determine the RFID. Use a default value of 3.0 if no installation damage testing has been conducted. The minimum value for RFID is 1.1.

(b) RFCR. Determine the creep reduction factor according to one of the following:

(1) Conventional creep testing according to ASTM D5262; or

(2) A combination of Stepped Isothermal Method (SIM) according to ASTM D6992 and conventional creep testing. Perform testing and determine creep reduction factors for a 75 year design life according to the procedures in Appendix D of FHWA-NHI-10-025, Design and

Construction of Mechanically Stabilized Earth Walls and Reinforced Soil Slopes – Volume II. If testing has not been conducted, default values for RFCR are 2.5 for polyester polymer, and 5.0 for polypropylene or polyethylene polymer.

(c) RFD. For polypropylene or polyethylene geosynthetics conforming to the requirements of Table

714-5, a default reduction factor of 1.1 may be used for RFD. For polyester geosynthetics conforming to the requirements of Table 714-5, a default reduction factor of 1.15 may be used for RFD if the soil has a pH between 5 and 8; and a reduction factor of 1.3 may be used if the soil pH is between 3 and 5 or between 8 and 9.
