Product Description Experience superior structural integrity with our Bridge Expansion Joint and Modular Expansion Joint, paramount in ensuring reliability.Haider's premier expansion joints encompass both single rail and modular types, offering unparalleled versatility and strength.Our expertly engineered expansion joint system facilitates seamless bridge deck movements while preserving a flawless, watertight riding surface for enhanced safety and comfort. Crafted for durability, these joints surpass the lifespan of bridge decks through a robust steel support system. They expertly blend strength to withstand traffic impacts with the adaptability to handle diverse deck movements, accommodating a movement range from 80 to 640 mm.Optimized both technically and economically, our expansion joint system is the quintessential choice for the vast majority of bridges, mastering the art of movement accommodation.Featuring a streamlined design where rubber resides between steel rails, this system adeptly handles expansion and contraction due to temperature fluctuations or impact loads, driven by the elasticity of the rubber.Enhanced with a support box bearing, the conventional assembled rail has evolved into a monolithic rail, significantly boosting durability and stability against cumulative fatigue while offering excellent waterproofing properties.Standard JT/T4-2004BS5400 Section 9.2 RubberNatural RubberNeopreneCRNaturalRubberNeopreneCRHardness(IRHD) 60±560±550±5/60±5/70±5Tensile Strength (M Pa)≥ 18171715.5Ultimate Elongation (%)≥ 450400450/400/350400/350/300Compression Set70 o C×22h70 o C×22h100 o C×22h<30<15<30<35Heat ResistanceTest Condition70 o C×168h100 o C×70h70 o C×168h100 o C×48hChange in Hardness-5,+100,+10<10<15(IRHD)Rate of Tensile Strength Reduction(%)<15<15Rate of Ultimate<20<40<20<40Elongation Reduction(%)Ozone Resistance25~50pphm,20% strain25~50pphm,20% strain40 o C×96h30 o C×96h No CracksNo Cracks
