Hong Kong-Zhuhai-Macao Bridge
At 50km in length, China’s Hong Kong-Zhuhai-Macao Bridge is currently the world’s longest sea-crossing bridge and the third longest bridge structure in the world.
The super structure is expected to reduce travel times from over three hours by land or one hour by ferry to just 30 minutes.
Protecting the superstructure
The chosen waterproofing solution would need to meet the construction standards of China, Hong Kong and Macao and offer the highest quality and durability. The waterproofing system also needed to withstand the warm marine climate both during application and for the long term.
The chosen provider would need to be able to meet the huge capacity of the structure within a tight delivery programme, and manage aspects the project’s commercial, logistical and technical support and quality assurance.
After extensive review and analysis of bridge deck waterproofing systems, the Hong Kong-Zhuhai-Macao Bridge Authority found that the ELIMINATOR® system was the ideal waterproofing solution.
ELIMINATOR® bridge deck waterproofing system
The ELIMINATOR® bridge deck waterproofing system was applied to approximately 500,000m2 of the three steel navigation bridge sections in mainland China waters. The use of Zed S94 enhances the strong bond of the ELIMINATOR® membrane to the deck.
Working in Asia’s warm climate means that the fast curing, flexible resins harden within minutes and are fully cured in just half an hour. The membrane can be trafficked if needed after just one hour, allowing trades to carry on working.
To complete the waterproofing, a thinner layer of red Tack Coat No.2 was applied. This tack coat dries quickly to a hard surface, which is resistant to the wheel loads of the asphalt paving plant. When the 230°C hot-poured asphalt is applied directly to this heat-activated tack coat, as it cools a strong chemical bond is formed, allowing the whole surface pavement system to work compositely in transmitting and dissipating the considerable stresses and strains induced by traffic loading and structural movements.
Such a momentous project relied on the highest levels of integrity, performance, service and quality, and GCP Applied Technologies proved that it was able to deliver.
