Hot Applied Joint and Crack Sealant shall meet the requirements of AASHTO M 324 (ASTM D 6690) for Type I Sealant, or Type II Sealant. Hot Applied Joint Sealant shall be selected from the Department's LIST III-4, "Joint and Crack Sealants". Refer to Subarticle 106.01(f) and ALDOT-355 concerning this list.
Cold Applied Joint and Crack Sealant shall be a resilient adhesive compound capable of effectively sealing joints from infiltration of incompressible materials and water throughout repeated contraction and expansion cycles. The sealant, when delivered, shall be capable of being used on the job site and may be placed by machine, pressure gun, or by hand. The compound, when used in other than horizontal joints, shall be capable of conforming to the slope face without sagging. Cold Applied Joint Sealant shall be selected from the Department's LIST III-4, "Joint and Crack Sealants". Refer to Subarticle 106.01(f) and ALDOT-355 concerning this list. The sealant shall be a homogeneous blend of materials, which may or may not require a primer. The sealant shall meet the requirements given in ASTM D 5893.
832.03Preformed Elastomeric Joint Seals
Compression type elastomeric seals shall consist of an approved seal shape formed from elastomeric material, designed to be installed and function in a compressed state. Installation of this type seal requires the use of a lubricant adhesive. This type seal when used on bridge decks will not require the use of a joint filler material unless such is specified by plan details.
Materials used in fabricating the preformed elastomeric seals shall conform to the requirements of ASTM D 2628 for Concrete Pavement and ASTM D 3542 for Bridges and be of the basic shape, dimension, etc. shown by the plan details. No factory or field splicing of seals in transverse joints 50 feet {15 m} or shorter in length will be allowed. On transverse joints over 50 feet {15 m} in length, one field splice will be considered for approval by the Engineer pending written request from the Contractor. This request shall specify the materials and details of performing the splice. Since the intent is to have one continuous seal meeting the above requirements, absolutely no patching of torn or damaged spots in the seal shall be permitted. In addition to the above, seals for bridge joints (including the joint between the bridge end and the bridge end slab) shall have a depth to width ratio of not less than 1 ( D/W 1). The lubricant adhesive used in installing the compression seals in joints shall meet the requirements of ASTM D 2835 for concrete pavement and ASTM D 4070 for bridge joints.
The installation of the seal shall be in accordance with the manufacturer's recommendation, plan details, approved shop drawings, and the following:
classification.
This type seal shall consist of an approved seal shape formed from elastomeric material without metal reinforcement, anchored by mechanical or other acceptable methods to anchor plates cast into or affixed to the joint edges.
The elastomeric material shall conform to the requirements of ASTM D 2628 modified to omit the recovery tests, with or without fiber or other types of acceptable non-metallic CONCRETE JOINT FILLERS, JOINT AND CRACKSEALANTS, AND WATERSTOP MATERIALS 699
reinforcement. The seal shall be of the basic shape and dimensions shown by plan details unless otherwise authorized in writing by the Bridge Engineer. Metal anchor plates shall conform to the requirements of ASTM A 36 or equivalent. Any sealant or lubricant shall conform to the requirements for lubricant adhesive noted in Subarticle 832.03(a) or an approved equivalent.
The installation of the seal shall be in accordance with the manufacturer's recommendations, the plan details, and the approved shop drawings.
This type seal shall consist of an approved shape formed from elastomeric material reinforced internally with metal strips with the seal affixed to the bridge deck by the method indicated in the plan details.
The elastomeric material used in the seal shall conform to the following: ELASTOMERIC SEAL SPECIFICATIONS TEST REQUIREMENT TEST METHOD Hardness, Durometer A 45 ± 5 ASTM D 2240 Tensile Strength 1800 psi {12.5 Mpa}, Min. ASTM D 412 Elongation @ break 400% Min. Compression Set, 22 hrs. @ 158 °F {70 °C} 20% Max.
