Precast prestressed concrete bridges have become the mainstream choice in the construction of highways, municipal and intercity transportation bridges in China.

In the past five years, the proportion of precast bridges in newly built highway bridges has skyrocketed from 18% to 46%.

By 2023, 14000 fully precast precast bridges will be completed, with a total output value exceeding 120 billion yuan.

In the field of medium and small span bridges, the proportion exceeds 70%, significantly higher than cast-in-place concrete bridges, steel bridges, composite bridges and other types.

The formation of this proportion advantage is not driven by a single factor, but the result of the multidimensional synergy of technological maturity, economic rationality, policy orientation, and engineering applicability, which is in line with the development trend of modern bridge construction towards “industrialization, greening, and efficiency”.
