Scope

Main technical content: The increasing demand for improving the durability of bridges, reducing traffic noise and maintenance costs of highway bridges, and the growing awareness of environmental protection have made the need for seamless bridges or low-noise seamless expansion devices increasingly urgent. By collecting and analyzing the experience of existing application projects of modular seamless expansion devices, as well as relevant research results, test and inspection results, and feedback information from users in the industry, this standard was developed. This standard can standardize the materials, production, construction, acceptance, maintenance, and repair of modular seamless expansion devices for bridges, ensuring the safety, reliability, and durability of these devices.
