Abstract: With the shift of China’s transportation infrastructure from large-scale construction to equal emphasis on construction and maintenance, as well as the deepening of policies for building industrialization, the construction methods of bridges are undergoing profound changes.

Plastic Rebar Chairs

As an important auxiliary structure of bridges, the prefabrication and assembly technology of crash barriers is becoming increasingly mature.

This article combines engineering practice and material innovation in recent years to systematically expound the comprehensive advantages of precast concrete guardrails in quality control, construction efficiency, safety management, environmental benefits, and economy, and demonstrate their inevitable trend as the preferred solution for future bridge engineering construction.
