Through the use of the Roadstone’s research and development laboratory in Dublin a wide range of trials were conducted to assess both the plastic and hardened properties of the concrete mixes including workability, workability retention and compressive strength.

Upon the completion of laboratory trials, operational trials were conducted to further assess the plastic and hardened properties. In addition Roadstone worked with other parties involved in the construction of the bridge to assess other parameters such as the pumpability of the different mixes.

Project Objective

Extending more than 300m over the River Barrow and with a 36 metre clearance the bridge is a key link for the surrounding communities and also for shipping navigation to the port of New Ross.

On completion, the bridge will be a three tower 887m long extrados bridge, the longest of its type in the world.

Our Role

Roadstone has designed these high strength concrete mixes for which in excess of 90% of the constituent materials were produced locally. The aggregates were sourced from Roadstone’s Kilmacow quarry in south Kilkenny and cement was sourced from Irish Cement’s Platin Works.

With construction nearing completion in excess of 4,000m³ of C80/95 concrete has been supplied to the Rose Fitzgerald Kennedy Bridge to date.
