Steel-UHPC Composite Bridge Decks Β· NC-UHPC Composite Structures Β· Bridge Rehabilitation Β· Export Price $280-380/ton
Designed for new long-span bridges. Deck stiffness improved by 50%, self-weight reduced by 30%, weld fatigue issues significantly reduced.
Construction period shortened from 3-6 months to 2-4 weeks. Service life extended from 15 years to 50-year maintenance-free. Validated on 30+ bridges.
π Pavement thickness 35-50mmPrestressed concrete body + UHPC bridge deck combination. Balances structural performance and economy.
Suitable for 20-50m medium-short span new bridges. Prestressed concrete reduces main body cost; UHPC solves bridge deck cracking and durability issues.
π° Best Cost PerformanceMore reliable bonding with original concrete. Solves both bearing capacity and durability deterioration simultaneously.
Excellent fire resistance β carbon fiber fails in fire, UHPC does not. Wet-method on-site construction, no specialized equipment required.
