report – Laboratory Results of Evaluations on Geotextiles and Geosynthetics. The NTPEP testing results must meet or
exceed the requirements listed in Table 712.09-1.
For all tests except Ultraviolet Exposure, the products Minimum Average Roll
Values (MARV), as published in the NTPEP report, must also meet or exceed the
requirements listed in the table. If no MARV value is published in the NTPEP
report, the manufacturer must submit to the Department certified test data showing
the MARV values for the product will meet or exceed the requirements listed in Table 712.09-1.
For
Type E material, supply fabric conforming to the requirements of AASHTO M288, Section 10, Table
8. The Department will accept Type E material based on certified test data.
All
minimum strengths shown are in the weakest principal direction.
Ensure
that the fabric is free of any treatment that might significantly alter its
physical properties.
During
shipment and storage, wrap the fabric in a heavy-duty protective covering to
protect it from UV deterioration, direct sunlight, dirt, dust, and other
debris.
Furnish
materials according to the Department’s Qualified
Products List (QPL).
