2. The storage and handling of the materials is the responsibility of CONTRACTOR
from the time the materials aze manufactured until the time the completed installation is
accepted. CONTRACTOR is responsible for preparing the storage location and far
• the protection of the materials from the elements (e.g. ultraviolet light, moisture,
temperature, etc.).
3. After CONTRACTOR has removed material from storage, CONTRACTOR shall
protect geogrid from puncture, dirt, grease, water, moisture, mud, mechanical abrasion,
excessive heat and other sources of damage.
4. CONTRACTOR shall preserve integrity and readability of the geogrid roll labels, and
store [he rolls such that MANAGER and CERTIFYING ENGINEER have access to
the package slips or roll labels for each roll to verify roll acceptance.
5. The rolls shall be stored on a prepared surface (not wooden pallets) and should not be
stacked more than two rolls high.
PART 2: PRODUCTS
2.01 MATERIALS:
A. Geogrid shall be Tensor UX 1700 HS or equivalent and shall have the following properties:

Notes:
1. Pemen[ open area measured without magnification by Corps of Engineers Method as specified m CW 02215 Civil Works Consruction Guide, November
1977.
2. Lang tens load capacity measlued by through thejunction tensile creep testing to 10,000 hours as described m Gmsynthetic Research Institute test method
GG3-87 "Creep Behavior and Long Term Design Load ofGmgrids."
3. ASTM D 1388-64 modified to account For wide specimen testing as described in Tensar test method TTM-3.0 "Stiffness ofGeosynthetics"
4. Secant modrdus at 2 % elongation measmed by Geosynthetic Research NstiMe test method GGI-87 "Geo®id Tensile Strength" No offset allowances are
made m Wculatrng secant rtwdulus.
5. Geogridjmctron shmgth andjunction efficiency measured by Creos}nthNic Research Irttitim[e test method GG2-87 "Geogrid Junction Strength."
6. The long-term allowable design strength (LTADS) is determined using the method outlined N GRI-GG4 "Detemtination of the Long Term Design Strrngtlt
of Stiff Geogrids." The GRI-GG4 method applies carious partial facrors of safety to account far construction damage, junction strenglb, connections,
chentical and biological degradation.
B. Geogrid shall be capable of retaining its structwe during handling, placement, and long-term
service.
