Nonmetallic Water Seals Art. 1054.01
d.Anchor Bolts, Threaded Rods, Washers, and Nuts. Anchor bolts, threaded rods, washers, and nuts shall either be stainless steel meeting the requirements of ASTM A 193 (A 193M), Class 2, or shall be according to the requirements of ASTM F 3125 Grade A 325 (F 3125M Grade A 325M), zinc- coated according to Article 1006.08(a).
e.Automatically End Welded Threaded Studs, Washers, and Nuts. Automatically end welded threaded studs, washers, and nuts shall be stainless steel meeting the requirements of ASTM A 193 (A 193M). Welding and inspection of the threaded studs shall be according to Article 505.08(m).
1052.03 Certification. The Contractor shall furnish a certification by the
manufacturer stating that the neoprene expansion joint and the accessory items meet the requirements approved by the Department. This will not constitute a waiver on the part of the Department of any requirements with respect to samples or samplings, and the right is retained to perform any test deemed by the Department as necessary to qualify the materials. SECTION 1053. PREFORMED ELASTOMERIC SEALS FOR CONCRETE
1053.01 Preformed Elastomeric Joint Seals For Pavement. Preformed
elastomeric joint seals used in pavement shall be according to ASTM D 2628. The lubricant-adhesive used with the seals shall be according to ASTM D 4070.
1053.02 Preformed Elastomeric Joint Seals For Bridge Decks. Preformed
elastomeric joint seals used in bridge decks shall be according to AASHTO M 297. The lubricant-adhesive used with the seals shall be according to ASTM D 4070.
1053.03 Preformed Elastomeric Strip Seals For Bridge Decks. Preformed
elastomeric strip seals shall be according to ASTM D 5973. The seal shall have a shallow “v” profile and shall contain “locking ears” that form a mechanical interlock when inserted in the steel locking edge rails. The size of the seal shall accommodate the rated movement shown on the plans. The lubricant-adhesive used with the seals shall be according to ASTM D 4070. SECTION 1054. NONMETALLIC WATER SEALS
1054.01 Description. Nonmetallic water seals shall be either thermoplastic or
rubber. All nonmetallic water seals shall be produced by a process that will provide a dense, homogeneous material free from imperfections. The cross section of the water seal shall be such as to ensure anchorage into the concrete by means of enlarged ends and/or fins and shall be approved by the Engineer. Nonmetallic water seal shall be capable of effectively sealing the joints in concrete against the infiltration of moisture. 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
