Product Description
China’s railways have evolved over 140 years, since the first official line opened in Shanghai in 1875. Railway lines are primarily composed of roadbeds, bridges, and tunnels. With the expansion of China’s rail network, the number of railway bridges and tunnels has grown steadily. In particular, high-speed railways and passenger dedicated lines—known as “China’s miracle”—require exceptional stability and speed, resulting in bridges accounting for over 50% of total line length. Thus, bridge deck waterproofing is a critical component of concrete bridge engineering. How can water penetration into bridge decks be effectively blocked to slow concrete aging and steel reinforcement corrosion, thereby improving the durability of concrete bridge structures? This is an area where "Jinzun" Waterproofing devotes significant research efforts.
