On the Assinie Highway in Ivory Coast, we executed the supply and installation of expansion joints across multiple bridge sections and roadway transitions. The key challenge was ensuring long-term durability and flexibility in a coastal environment subject to heavy traffic loads and extreme temperature variations. We selected high-performance joint systems designed to absorb movement, reduce vibration, and prevent water ingress. Our team ensured precise alignment and secure installation, delivering a robust, low-maintenance solution that enhances the safety and longevity of the highway infrastructure.
