An Expansion Joint is a mechanical feature used to absorb the expansion and contraction of materials due to temperature changes or other forces. These joints are essential in structures like bridges, highways, and buildings to prevent damage caused by thermal expansion, settling, or vibrations. Features: 1. Absorbs thermal expansion. 2. Reduces stress and pressure on structural components. 3. Prevents cracks and structural damage. Advantages: Expansion joints ensure structural integrity by accommodating movement, making them indispensable in maintaining durability and longevity of infrastructure. Applications: Commonly used in construction of highways, bridges, railway stations, and in industrial structures where temperature fluctuations are significant. These joints protect the surface from cracking and deterioration, extending the lifespan of the structure.
