Dynapac leads first graphene-modified asphalt surface overhaul

AFTER 10 YEARS OF SERVICE, THE NANNING BRIDGE, A LANDMARK STRUCTURE IN NANNING CITY, UNDERWENT A COMPLETE SURFACE OVERHAUL AT THE END OF MARCH 2018.
This overhaul, which was the very first comprehensive commercial application of graphene-compound rubber modified asphalt technology in high-class road/bridge surface consutrction all over the world, was completed succesfully on June 4th.
Adding graphene to asphalt significantly improves the durability and sustainability of asphalt road surfaces, thus making the asphalt less likely to soften in warm temperatures or harden and crack in cold ones.

Guangxi University and Guangxi Zhenglu Machinery Technology Co. Ltd. jointly develop this revolutionary technology. During its past twenty-years of growth, Guangxi Zhenglu has been responsible for many high-quality projects with excellent performance thanks to their broad Dynapac fleet. “Dynapac has the same enterprise values as we do and Dynapac compaction & paving equipment are indispensable tools on every one of our high-class construction projects,"explains Mr. Gui Li Fa, the president of Guangxi Zhenglu.

Two SD2550CS pavers with HEE (Hydraulically Extendable Ends) screeds, six CC6200 duplex rollers & two CP275 tired rollers, executed the impressive overhaul of the Nanning Bridge, with a project length of more than 1,000 meters and a width of 35 meters.

This paver is the most optimal and flexible tool for widening sections in highway construction. It is not only suitable for large paving widths, it can also adapt seamlessly to other narrower paving widths of any given highway situation. For example, when using it for the paving jobs in the continuous narrowing or widening of bridge ramps, variable sections or widening sections in tunnels, bus stations on municipal roads, emergency-parking zones on high ways etc., there is no need to re-assemble the screed thus maximizing working efficiency.
