N.S. GEOGRID (01-26)
1 DESCRIPTION
This item consists of furnishing and placing geogrid reinforcement in the areas shown on the
plans, and as directed by the project engineer, prior to placement of base course.
2 MATERIALS
General Requirements: The geogrid will be a biaxially oriented polymer grid structure
composed of polypropylene or high density polyethylene with apertures designed to interlock
with the surrounding fill material. Weld or interweave the joints at the crossover points in such a
manner that the elements will not separate under handling and construction activities or under
dynamic loads anticipated over the life of the structure. The geogrid will be resistant to damage
during construction, including ultraviolet light degradation, and have long-term resistance to
chemical and biological degradation caused by the fill materials being reinforced.

Detailed Requirements:
Property Test Method Requirements
Aperture Size, in. I.D. Calipered 1.0 - 1.5
Open Area, percent COE Method 70%
Flexural Rigidity, lb-ft ASTM D1388 0.018
Tensile Modulus at 2%

All numerical values represent minimum average roll values required in the designated
direction.
Submit a Certificate of Compliance that the geogrid meets the physical properties outlined
above. The department reserves the right to randomly sample and test geogrid material.
3 CONSTRUCTION
Place the geogrid in continuous sheets parallel to the centerline. Overlap adjacent sheets of
geogrid a minimum of eighteen (18) inches. Ensure that geogrid sections do not separate
during construction.
Cut the geogrid to conform to curved sections so as to maintain placement parallel to the
centerline. Ensure that excessive buckling of the grid material does not occur. Excessive
material quantity, if any, required for making curves shall be at no direct pay.

This specification is for informational and illustrative purposes only and a bidder for a State Project should not rely on the substance
or content of this document for any purpose. This specification document is not a contract document unless expressly included as
part of a Construction Proposal by the Department.
Tracked equipment will not be allowed to operate directly on the geogrid. Remove and replace
damaged geogrid with new geogrid or cover with a second layer of geogrid extending three (3)
feet (1 m) in each direction from the damaged area.
Label or tag each geogrid roll to provide product identification sufficient for field inventory and
quality control purposes. Store rolls in a manner which protects them from the elements. If
stored outdoors, elevate and protect from ultraviolet light.
4 MEASUREMENT
Geogrid reinforcement will be measured by the square yard of covered area.
5 PAYMENT
Geogrid reinforcement will be paid for by the square yard of covered area at the contract unit

NS-830
Carbon Fiber Reinforced Polymer Repairs
PART 1 - GENERAL
1.01 DESCRIPTION
This system consists of furnishing all labor, materials, tools, and equipment, to perform all
work necessary for and incidental to repairing or strengthening timber piles with a Fiber
Reinforced Polymer (FRP) System and adding a protective top coating in accordance with
the plans and specifications.
The FRP system comprises reinforcing fabrics and resin components installed using hand
or mechanical wet lay-up methods on the surfaces of concrete members. When the plans
do not provide the number of plies and/or ply thickness, determine the required number of
plies and/or ply thickness in accordance with these specifications and manufacturer's
specifications.
1.02 RELATED WORK
Refer to the applicable sections on bridge rehabilitation, erosion control, and maintenance
of tra3ic for coordination.
1.03 SUBMITTALS
A. Product Data: Manufacturer's specifications, material safety data sheets, and
structural data sheets for the FRP laminates, structural bonding epoxies, spacers, and
annular grout.
B. Design Calculations: Structural design calculations and shop drawings sealed by a
Registered Professional Engineer licensed in the State where the bridge is located.
Calculations must demonstrate that the combined host timber pile residual section,
annular grout core, and field-fabricated structural jacket satisfy the dead and live load
demands under AASHTO LRFD specifications.
C. Contractor Qualifications: Written documentation proving that the installation
contractor and crew have been explicitly trained and certified in writing by the FRP
system manufacturer within the last 3 years.

1.04 QUALITY ASSURANCE
A. Ensure compliance with all environmental regulations regarding timber pile repair and
strengthening using structural composite.
B. Inspector shall inspect FRP repair as required by manufacturer's recommendations.
C. Contractor shall avoid damage to any structural components during timber pile repair
operations.
D. Inspector shall inspect all bridge structures prior to and after repairs.
PART 2 - PRODUCTS
2.01 MANUFACTURERS
A. PileMedic(R) by QuakeWrap, Inc. (Baseline System)
B. Approved Equal satisfying all performance and material criteria of this specification.
C. Provide a structural pile repair jacket system from any manufacturer capable of meeting
or exceeding the minimum material, physical, and performance criteria defined in this
specification to ensure open, fair bidding competition. The system must supply
structural confinement (hoop strength) and flexural reinforcement, acting as a
structural containment mold that works compositely with the high-strength annular
grout filler to restore or exceed 100% of the pile's original design load capacity.
2.02 MATERIALS
A. Structural FRP Laminate: * The laminates shall be pre-manufactured in a controlled
factory environment using carbon or glass fibers embedded in a vinyl ester or epoxy
resin matrix.
B. The sheets must feature a textured or polyester scrim surface on both faces to
maximize chemical adhesion with the bonding resin and the annular grout.
