The expansion device "Hybrid Joint Type 3LII" from Crittec Industrial has been proven to have a durability of 100 years! A fatigue loading test was conducted by a third-party organization. It successfully withstood repeated harsh loading, clearing the equivalent of 12 million cycles, which corresponds to 100 years. This aligns with the 100-year design supply period for bridges. Since there is no need to replace the expansion device for 100 years, it reduces lifecycle costs. Additionally, as it is a maintenance-free joint that eliminates the need for sound inspections associated with regulations, it also reduces maintenance costs. This is a revolution in expansion devices! The "Hybrid Joint Type 3LII," with its ultra-long-term durability of 100 years, is not a new product; it has already been widely adopted across national highways as a product that meets NEXCO specifications. We encourage you to adopt the "Hybrid Joint Type 3LII," which contributes to the longevity of bridges.
