The Importance of Concrete Barriers

The Importance of Concrete Barriers Increases Every Day: While the metrobus that crossed the opposite lane with the rupture of the steel barriers in the metrobus accident in Istanbul recently caused many injuries and material damage, the road safety problem came to the fore again.
Concrete barriers that are mandatory to be used in England and Ireland during the accident; While preventing the vehicle from passing to the opposite lane, it also contributes to the environment and traffic safety with its sound insulation feature. According to researches, concrete barriers; psychologically, it also enables drivers to drive more carefully.
While discussing the sociological and humanitarian dimensions of the traffic accident with the discussion of the Metrobus driver and the passenger; The safety of roads separated by steel barriers was brought to the agenda. Cement Manufacturers Association of Turkey (CBT) CEO Ismail increasing clouds with steel barrier breaking injured in accidents with property damage and loss of life advocated concrete barriers can be reduced with the number.
Cloud; “We regretted how insufficient the steel barriers were in the metrobus accident in the past days, and we have seen again in the country. In places where such accidents are at high rates, we should consider once again that concrete barriers should be a necessity for both life safety and property safety. Concrete barriers, which have been used in the middle refuges for many years, although there is no legal obligation in the UK and Ireland and in European countries, prevent the accident vehicle from leaving the road and cause greater accidents; It helps to minimize loss of life and material damage. Concrete barriers in the central reserve prevent a colliding vehicle from rolling over and going in the opposite direction, and more effectively prevent damage to vehicles in the opposite direction. Especially in accidents involving heavy tonnage vehicles, we see an increase in loss of life and material damage due to crossing the opposite lane. The ability to hold the striking vehicle by the barrier, the lateral deformation of the barrier, the stability of the striking vehicle, the direction of movement of the vehicle after the collision and the impact effects of the passengers give positive results with concrete barriers. In addition, according to researches, concrete barriers enable drivers to drive more carefully, psychologically. said.
Tumble-throwing, rolling into the abyss, violent impact, concrete barrier against crossing the lane
Concrete barriers; While it is designed to reduce the impact of the impact on the vehicle, it keeps both traffic and environmental safety at the forefront in order to prevent the traffic noise from spreading to the environment and to shield the traffic lights from the opposite direction. Concrete roads are placed in front of roadside obstacles to ensure more safety of traffic; In addition to the dangers that may occur in the event of an accident, the vehicle is used against roll-over, rolling into the abyss, violent impact, and crossing the counter-lane.
Concrete barriers are more economical than steel barriers
Cement, which is the main material of concrete, is a completely domestic product which can be easily obtained from factory and grinding plants scattered around the country. Concrete barriers are easily produced as prefabricated or in-situ castings. Prefabricated concrete barriers are placed in place by crane. There is little to no risk of assembly. The lifetime of the concrete barriers is 40-50 years. Due to its high strength and mass, it is not affected by the impacts during its service life and does not wear out. Therefore, it is much more economical in long term than steel barriers. Even if the initial construction cost is higher than that of steel barriers, it is economical in terms of useful life compared to steel systems due to low maintenance and operation costs in long term. In case of using a barrier for heavy vehicles (heavy-duty barriers), the concrete barrier is more economical both in the initial installation phase and in the long run than in the steel system. Concrete barriers can also safely stop a second vehicle that crashes into the same area after an accident.

    1. Each concrete barrier cannot be a suitable barrier for transport routes. The type of concrete barrier, developed by yıl Stewens Institut of Technology tipi in New Jersey in the USA in the 1950 and entered as New-Jersey Barieri and Jersey-Barrier in the literature, has been used in all advanced countries since 1959. In parallel with the highway manufacturing in our country in the following years, it has been standardized and implemented by TC Highway in the name of Standard-Highway-Barrier. This barrier, which resembles an inverted mushroom, is available in various sizes (base 60, 81,5, 100 cm). The base height of the barrier is approximately 20 cm, which is then obliquely bent upward, and the post is a conical wall (height 80, 100 cm, etc.). This barrier type, due to its geometry, prevents the friction damage on the side of the crashing vehicle in the event of a lateral vehicle crash. It permits collision damage in parts of the cross-border container, just like the front / rear. Due to its own weight on the minimum 1 tone and its anchoring on the road floor, it prevents the passage of the barrier by the vehicle at normal speeds. The system is highly rigid, ie the flexural coefficient is negligible.
      In Istanbul, on the Metrobus roads; This Jersey type concrete barrier (Roadway Standard Concrete Barrier) is an inevitable necessity to replace the steel short poles and the steel wire rope between the strips of the lane and the right / left sides of the lane.
      Another unavoidable measure is that it is inevitable that many parts of the metrobus line need to be switched to a Guidance-Path system (which has a forced routing guide on the road in the development of metrobus starting in 1979)!
