Art. 1054.02 Nonmetallic Water Seals
1054.02 Polyvinyl Chloride (PVC) Water Seal. The water seal shall be
extruded from a specially compounded thermoplastic material consisting of a basic resin of polyvinyl chloride with additional resins, plasticizers, stabilizers, or other ingredient materials needed to provide a satisfactory water seal. Samples taken from the finished water seals shall meet the following requirements.
a.Tensile Strength. The tensile strength shall be not less than 1500 psi (10,300 kPa).
b.Elongation. The elongation shall be not less than 300 percent.
c.Cold Bend. Specimens 1 in. (25 mm) wide and approximately 6 in. (150 mm) long shall be cooled until the material is between 0 and – 10 °F (–18 and –23 °C), then immediately bent 180 degrees around a mandrel 1/4 in. (6 mm) in diameter. The specimens shall show no cracking.
d.The material shall have a low water absorption, a high resistance to acids and alkalies, and little deterioration under accelerated aging tests.
1054.03 Rubber Water Seal. The water seal shall consist of natural rubber or
a high grade synthetic rubber polymer compounded to produce satisfactory physical properties and aging characteristics. Samples taken from the finished water seals shall be according to the following.
a.Tensile Strength. The tensile strength shall be not less than 2500 psi (17,200 kPa).
b.Elongation. The elongation shall be not less than 400 percent.
c.Hardness. The Shore A Durometer hardness shall be 60 to 70.
d.Absorption. The absorption of water by weight shall be not greater than five percent.
e.Specific Gravity. The specific gravity shall be 1.15 ± 0.05.
f.Strength After Aging. The tensile strength after the air accelerated aging test of 48 hours in oxygen at 158 °F (70 °C) and 300 psi (2,100 kPa) shall be not less than 80 percent of the original tensile strength.
g.Test Methods. Tests will be made according to the following methods.
1.Tensile Strength - ASTM D 412
2.Elongation - ASTM D 412
3.Specific Gravity - ASTM D 297
4.Absorption - ASTM D 570
5.Hardness - ASTM D 2240 External Sealing Band Art. 1057.01
h.Test Samples. The nonmetallic water seal will be sampled on the job or at the source of supply, as determined by the Engineer. The Contractor shall furnish 18 in. (450 mm) samples representative of the material being furnished. At the option of the Engineer, the manufacturer of the water seal may be required to submit a statement that the material furnished conforms to these requirements. SECTION 1055. MASTIC JOINT SEALER FOR PIPE
1055.01 Requirements. Cold-applied bituminous sealer for culvert and sewer
pipe joints shall be a bituminous material of such consistency that it can be applied to the joints with a trowel when the temperature of the air is between 20 and 100 ºF (–7 and 38 C). The bituminous material shall adhere to the concrete or clay pipe so as to make a watertight seal and shall not flow, crack, or become brittle when exposed to the atmosphere. The mastic shall also be according to the following specific requirements. Property Value Penetration 77 °F (25 °C), 150 g, 5 sec, with cone, 0.1 mm 175-300 Loss on Heating, 325 °F (163 °C), 5 hr, 50 g, percent 20 max Inorganic content [complete burn, 1200 to 1400 °F (645 to 760 °C)], percent 15-40 Flow at 140 °F (60 °C), centimeters 0 Pliable at 0 °F (-17 °C) Yes The mastic shall be delivered to the project in suitable containers for handling and shall be sealed or otherwise protected from contamination. The container shall show the brand name, net volume or weight, and the requirements for application. SECTION 1056. RUBBER GASKETS AND PREFORMED FLEXIBLE JOINT SEALANTS FOR CONCRETE PIPE
1056.01 Requirements. Rubber gaskets shall be according to ASTM C 443
(C 443M). Preformed flexible joint sealants shall be according to ASTM C 990 (C 990M). SECTION 1057. EXTERNAL SEALING BAND
1057.01 Requirements. External sealing band, mastic, and film shall be
according to ASTM C 877 (C 877M). SECTION 1058. RESERVED SECTION 1059. RESERVED
