U-Turn Bridge Bottom Slab Strengthening in Ratchaburi Province with SMARTFIBER-SHEET UT70-30
Project Overview
This project involved the structural enhancement of a horseshoe-shaped U-turn bridge in Ratchaburi Province. Engineering assessments found that the precast concrete bottom slabs did not meet the load-bearing requirements set by the Department of Highways.
To resolve this, the design engineers specified the use of SMARTFIBER-SHEET UT70-30, a carbon fiber reinforced polymer (CFRP), to strengthen the underside of each precast slab.
Material and Application Details
✅ Material Used: SMARTFIBER-SHEET UT70-30
- High-strength CFRP sheet applied to the underside of precast slabs
- Tensile strength exceeding 3,100 MPa
- Lightweight, easy to install, and highly resistant to moisture and corrosion
- Ideal for bridge and infrastructure applications requiring fast, non-invasive strengthening
🛠️ Installation Process
- Structural evaluation and reinforcement layout design
- Concrete surface cleaning and preparation
- Installation of SMARTFIBER-SHEET UT70-30 using epoxy adhesive
- Final inspection through Non-Destructive Testing (NDT)
✅ Project Outcomes
- Structural load capacity brought up to code with minimal disruption
- Reinforced slabs now safely support ongoing traffic and environmental loads
- Durable, cost-effective solution with reduced maintenance requirements
- A model application of CFRP technology in civil infrastructure strengthening
