Expansion joints play a crucial role in accommodating thermal expansion and contraction of concrete and asphalt pavements, thereby preventing structural damage and ensuring smoother travel for vehicles. However, inconsistent quality and improper installation of these joints have been a longstanding concern, leading to road hazards and maintenance issues.

The certification process will involve rigorous testing and adherence to specific standards for materials, design, and installation methods. This measure is expected to curb substandard practices and promote uniformity in road construction projects nationwide.

Industry experts welcome the initiative, noting that standardised certification will not only improve road safety but also bolster the durability and longevity of highways and expressways. By ensuring that expansion joints meet prescribed quality benchmarks, authorities aim to reduce maintenance costs and enhance the overall reliability of India's road infrastructure.

Implementation of the new certification requirement is set to begin in the coming months, with regulatory bodies working closely with stakeholders to streamline compliance and ensure effective enforcement across all road expansion projects.
