LIFE+ New Jersey Project has entered its final stretch, with the installation in a road of a section of the concrete with end of life tires (ELTs) barrier developed by SIGNUS and tested in Cidaut facilities.

Shortly after the broadcast event held in the Committee of the Regions in Brussels, last March, Project Consortium proceeded to the start of the final milestone of the project, the installation, in the M-511 highway of the Community of Madrid Road Directorate, a stretch of concrete safety barrier with ELTs chips in concrete composition.


This barrier proves to be safe in the corresponding full scale crash test (according to the EN 1317 standard for road restrain systems), it has a lower density when compared to equivalent barriers made of conventional concrete. Furthermore, its lower density contributes to a lower transport costs and therefore a lower carbon footprint.

The use of ELTs chips in the concrete composition, as well as providing mechanical properties equivalent to those of conventional concrete, also the detached elements are reduced, since the elastic properties of the ELTs chips contribute to better hold of the cracked areas after an impact.

The project partners visited in mid-June the pilot stage to check in detail the good adaptation of the new barrier installation developed highway.

LIFE + New Jersey Project that started in September 2011, ends within June 2015, proving that residues such as those coming from the tire’s end of life can be used to improve the mechanical properties of concrete.
