1075Centrifugally - Cast Fiberglass-Reinforced Polymer Mortar Pipe

1075.1 Scope. This specification covers centrifugally-cast fiberglass-reinforced polymer mortar pipe to be used

in pipejacking and microtunneling for horizontal boring applications under roadways.

1075.2 Acceptance. Acceptance of the material will be based on the manufacturer’s certification and upon the

results of any tests required by the engineer.

1075.3 Manufacture.

1075.3.1 Pipe shall be manufactured from polyester resin systems with a proven history of acceptable

performance for the particular application. The historical data shall have been acquired from a composite material of similar construction and composition as the proposed product.

1075.3.2 Pipe shall be manufactured from reinforcing glass fibers of commercial grade E-glass filaments with

binder and sizing compatible with impregnating resins.

1075.3.3 Pipe shall be manufactured from silica sand, with a minimum of 98 percent silica, and a maximum

moisture content of 0.2 percent.

1075.3.4 When used, resin additives, such as curing agents, pigments, dyes fillers, thixotropic agents, etc., shall

not detrimentally affect the performance of the product.

1075.4 Documentation. The manufacturer shall provide certification to the contractor that the material provided

is in accordance with ASTM D 3262 and that pipe joints meet the performance requirements of ASTM D 4161. The certification shall state the manufacturer’s name and shall have attached typical results of tests on the material and pipe joints.

1075.5 Construction Inspection. Pipe will be inspected for defects prior to installation. Damaged pipe will be

rejected. Any pipe that appears cracked near the joint will be rejected.
