Second Jiao Jiang BridgeOverview
The Second Jiao Jiang Bridge and the project for a further connection link are located in the mouth of the Jiao Jiang River of Taizhou Bay in the Zhejiang Province.
The main bridge features a length of 3’702 m and it has been designed according to the 1st Road Building Standard. The bridge was officially opened to traffic in 2014.
Being designed as a cable stayed bridge of composite girder structure with dual-pylon and dual-cable plane, each pylon features a length of 153 m and is designed as diamond-cut. The main span is 480 m.
Its construction has vital importance on promoting balanced infrastructure development among Chinas’s regions.
In 2014, mageba manufactured four TENSA-MODULAR expansion joints of type LR15, each with 15 individual gaps between surface beams and accommodating longitudinal deck movements of up to 1’200 mm.
The expansion joints feature anti-skid coating ROBO-GRIP that consists of five layers of low-viscosity resin and high-friction additive. The use of this material improves tyre grip and consequently safety as skidding of vehicles in wet conditions will be prevented. Being originally developed for building structures where high friction and high durability under extreme conditions are required, the excellent properties also proved to be a huge benefit for large bridge structures.
