More than 170 full-scale crash tests

These systems provide the protective measures required to prevent many road traffic accidents. REBLOC® systems verifiably contribute to increasing traffic safety. They significantly fulfill the prerequisites of modern vehicle restraint systems according to the European standard EN1317 as confirmed in extensive and real-life crash tests. Complying with the requirements of high containment levels guarantees that a breakthrough of vehicles is impeded in the best possible way. The continuously closed surface also increases safety for motorcyclists.

REBLOC® invests a considerable amount of money in research and development anually to guarantee the safety of REBLOC® systems. Our focus during the ongoing new developments is on safety, durability, practicality and economic efficiency. The most modern simulation and calculation processes, complex testing facilities and testing instruments a well as an experienced team of development engineers and material experts are the prerequisites to always be up to date and to design technology innovatively. Short decision processes and our know-how acquired over many years enable us to react at short notice and to offer quick and adequate solutions.

Road restraint systems in accordance with EN1317

In order to improve and maintain highway safety, the design of safer roads requires, on certain sections of road and at particular locations, the installation of road restraint systems. The European Standard  EN1317 specifies requirements on impact performance of safety barriers, including vehicle parapets. These consists of containment level, criteria for test methods, working width, vehicle intrusion and impact severity level.

Containment level

The containment level determines the criterias for the vehicle impact and defines the containment level of the vehicle restraint system on the basis of impact speed, impact angle and total mass of vehicle.

Working width

The working width consists of the system width and the deflection of the vehicle restraint system caused by a vehicle impact.

Impact severity level (ASI)

This theoretical calculated value determines the severity of the consequences of the impact on the car’s occupant and is relevant for the occupant’s risk of injury. They are not allowed to exceed a certain value.
