Joint Sealer Sample Clauses
The Joint Sealer clause specifies the requirements for materials and methods used to seal joints in construction projects. It typically outlines the types of sealants permitted, the preparation of joint surfaces, and the application procedures to ensure a watertight and durable seal. By clearly defining these standards, the clause helps prevent water infiltration, material degradation, and structural damage, thereby ensuring the longevity and integrity of the finished work.
Joint Sealer. The joint sealing material must be resistant to oil, the most common chemicals and sunlight. It shall be of permanent elasticity, be suitable to carry the structural deformations and must possess an outstanding adhesion to the concrete. The elastic extension must be at least 150 % and the resistance to heat shall be between 50 degrees Centigrade and +120 degrees. Centigrade, which are to be confirmed by submission of verified test certificates. Joint sealer shall be the make of a recognised manufacturer, such as THIPFLEX 600 of EXPANDITE or equivalent approved. Joint sealer shall be supplied with primer coats, backing material and/or bond breakers to the joint fitter, as required by the manufactures recommendations. The Contractor shall submit to the Engineer a statement from the manufacturer(s) of the joint filler and sealing materials, that these materials are suitable under the prevailing local and structural conditions.
Joint Sealer. THE LAST SENTENCE OF THE SECOND PARAGRAPH IS CHANGED TO: If splicing of a sealer is allowed, ensure that the sealer at the splice point has no significant misalignment at its sides or top and that misalignment at the bottom does not exceed half of the bottom wall thickness.

A. Requirements for HMA Mixing Plants.
A. Scope. This test method is used to determine the susceptibility of HMA specimens to fatigue or reflective cracking. This test method measures the number of cycles to failure.
B. Apparatus. Use the following apparatus:
1. Overlay Tester. An electro-hydraulic system that applies repeated direct tension loads to specimens. The machine features two blocks, one is fixed and the other slides horizontally. The device automatically measures and records a time history of load versus displacement every 0.1 sec at a selected test temperature. The sliding block applies tension in a cyclic triangular waveform to a constant maximum displacement of 0.06 cm (0.025 in.). This sliding block reaches the maximum displacement and then returns to its initial position in 10 sec. (one cycle).
Joint Sealer. Sealers shall be either hot or cold applied. Hot applied sealers shall comply with B.S. 2499. Cold mastics shall be applied by gun and where more than 12 mm deep shall include filling with loose packing yarn to within 2 mm from the outer face. All joint sealers are to be approved by the Engineer prior to their use.
Joint Sealer. Joint sealant shall be a multi-component polyurethane type and shall comply with ASTM C920 Class 25. Joint sealants shall be installed according to the manufacturer’s recommendations.
