ASTM STANDARD REQUIREMENT Durometer - Shore A D 2240 50 min. Tensile Strength D 412 1500 psi (10,300 kPa) min. Ultimate Elongation D 412 200% min. Compression Set 22 Hours @ 212 °F (100 °C)(Method "B") for Polychloroprene D 395 35% Max. @ 158 °F (70 °C) (Method "B") for EPDM 25% Max. Low Temperature Brittleness (Method "A") D 2137 Pass Non-brittle after 3 min. @ 34 °F (1 °C) Ozone Resistance Procedure "B" D 1149 No Cracks - D 518 100 PPHM Ozone for 70 Hours @ 100 °F (38 °C) Sample Under 20% Strain Bond During Vulcanization (Method "B") D 429 80% R When test specimens are cut from the finished product, a ten percent variation in "Physical Properties" will be allowed.
b.Steel reinforcement in anchor blocks. The steel reinforcement in anchor blocks shall be bonded to elastomer during the vulcanization process and shall be according to ASTM A 1011 (A 1011M), Grade 36, SAE 1020, or equal.
c.Adhesive and Sealant. The adhesive/sealant bedding compound for bonding the expansion joint seals to the concrete or steel seats shall be a polysulfide grout meeting the requirements of Federal Specification MMM-G- 650B, Grade C with 50 percent filler material allowed. The sealant for sealing between the ends of elastomeric anchor blocks, between edges of concrete block-out and anchor blocks, and for filling bolt hole cavities shall be a one or two part, non-sagging polysulfide or polyurethane black sealing compound meeting the requirements of Federal Specification TT-S-00230C, Type II. Bedding and sealing compounds that do not meet the specifications shall not be used without prior approval of the Department. Other compounds submitted for approval will be evaluated on their ability to provide equivalent physical and functional properties. 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.
