abstract = {The most important mechanical factors in an impact scenario of a vehicle into a concrete safety barrier are vehicle speed, the impact angle, the static stability factor of the vehicle as well as the concrete safety barrier design and conditions. Concrete safety barriers (CSB) are primarily designed to minimize vehicle damage by allowing the vehicle to be lifted when riding up on the lower slope and then redirected back on to the road. In some cases, though, the vehicle-CSB contact might end up with a rollover often with fatal consequences. To reduce the rollover risk, different concrete barrier shapes were designed in the past while omitting the importance of the friction coefficient between the tyre and barrier. Therefore, the aim of this paper is to research and emphasize the importance of the friction coefficient between the vehicle tyres and the CSB in rollover accidents. For that purpose, a series of Finite Element analyses were performed using different values of the friction coefficient between the vehicle tyres and the CSB. Experimental measurements of the coefficient of friction between the rubber and CSB blocks of different surface were additionally performed in dry and wet conditions in order to examine the real onsite friction characteristics. The results show that the coefficient of friction can have a crucial impact in vehicle rollover scenarios and should therefore be kept as low as possible by the concrete safety barriers manufacturers and maintainers.},
