“Concrete Accessories” for Overhead Noise Barrier on A 86 near Paris

Customized Products by Technique Béton for New Motorway A86, Jouy en Josas, France

As one of the busiest streets in Europe, the Boulevard périphérique, a multi-lane highway that leads around Paris, is notorious for its regular traffic jams.

A new beltway, A 86, is now being built in order to relieve traffic congestion in Paris and to facilitate quick and easy connections between the different Parisian suburbs. The beltway leads around the Boulevard Périphérique at a distance between 5 and 7 km, replacing federal road RN 186, which will no longer be adequate for the high traffic volume.

Since reducing street noise is an important element in this construction plan, an overhead noise barrier is being built on the modern multilane highway between Jouy-en-Josas and Vélizy-Villacoublay. This gallery-like barrier is going to reduce traffic noise to a maximum of 65 Decibels for the adjacent residential areas. The overhead noise barrier’s architecture is appealing and aerial. Furthermore, the barrier will blend in due to its being covered with resilient climbing plants.

Since the construction plan also included finding a solution for an easy and safe crossing of the motorway, a new pedestrian underpass was built.

Technique Béton delivered mould release agents Biodem SI 1 and Cirtec L to the job site. Both allow the easy removal of concrete from the mould while creating a homogenous highquality surface. In addition, Biodem SI 1 is especially environmentally friendly due to its biodegradability of over 60%.

Once again, Technique Béton’s products were chosen by the owner because of their excellent quality and reliability.
