GROUNDSLEEVE PRODUCT TEST
Numerous tests and load tests were carried out on various road barrier posts connected to the GroundSleeve system:
- Dynamic tests were carried out on the new GROUNDSLEEVE in Norway, August 2022;
- Both static and dynamic load tests along the A12 motorway with the creation of an FEM model;
- Test with “MARTE” equipment on the A22 – Mantua motorway;
- ANAS test on post C ” 160 x 120 x 4 ” (H3) on the state road SS309 “Romea”;
- Both static and dynamic Push-Pull tests at the CSI laboratory in Milan, Bollate;
- Test at the Consorzio Autostrade Siciliane on sections of the A18 and A20 motorways in Sicily.
All tests have been successfully passed, ensuring in particular that the plastic yield point of the post conforms to the crash test.

Plasticization of the HEB120 upright
Test of the CONCRETE SLEEVE product in Tor Vergata
The tests were performed in the laboratory of the Department of Civil Engineering and Computer Engineering of the University of Rome Tor Vergata” – Prof. Alberto Meda.
Several static thrust tests were carried out on a post in S355 to verify the behavior of the ConcreteSleeve pocket. In addition to the excellent resistance, the test also demonstrated a surprising response of the resistance by the fiber-reinforced concrete curb.
The interlocking constraint at the end of the slab is composed of a system of HEB 300 beams compressed by 2 hydraulic jacks of 2000 kN each.
The rigid joint has been set up to support the maximum load on each jack with a total action of 4000 kN.

Crash Test of the CONCRETE SLEEVE product at CSI Milan
On 20 and 21 June 2019 at the test field of the CSI laboratory in Bollate (MI), 2 Crash Tests (TB11 and TB81) were carried out in real life on the ANAS barrier called ‘H4BPSMC-CL M4’, inserted in the ConreteSleeve pocket which in turn was immersed / embedded in the fiber-reinforced concrete curb.
All tests were performed according to EN 1317-1 and EN 1317-2.
The ConcreteSleeve anchoring system has successfully passed this test as well, without breaking and / or deforming, allowing the post to deform exactly at the predefined height. The fiber-reinforced concrete foundation resisted without showing any kind of fracture and / or cracking.
