Concrete barrier lumenrt template1/4/2024 Entertainment events and festivals: Concerts have a lot of activities going on at the same time.Barriers are strategically placed to separate the construction site from roadways and pedestrian routes. The use of heavy machinery and equipment can be distracting to the drivers and onlookers. Construction works: Construction sites pose various dangers to the workers and those using the roadways surrounding the area.Among the useful ways concrete barriers promote security are: Safety is the number one function for concrete barriers. The following are ideas you can adopt, or creatively combine to functionally and affordably use concrete barriers and retaining walls to your advantage. Concrete barriers have many uses that can make your life easier. It is impossible to include all the uses of concrete barriers. However, not many people take their time to think about the versatile nature and use of concrete barriers. You probably have concrete retaining walls in your compound or the outside of your workplace. Motorcyclists also support concrete barriers because their smooth face contrasts with the dangerous posts and bolts that are characteristic of other systems.It is hard to cross two streets today without passing by concrete barriers. Concrete barriers are increasingly seen as a way of ensuring free-flowing traffic on major routes as well as giving motorists the highest levels of protection. This usually results in lane closures with all their associated traffic congestion and risks the lives of the workers repairing the barriers. Even when struck by vehicles they rarely require repairs, unlike other systems which have to be repaired after each time they have been hit. In-situ concrete barriers are virtually maintenance-free. It is replacing steel with N2 containment, W3 or W4. For example, specified by the UK Highways Agency, the concrete step barrier has an H2 level of containment (13 tonne coach) and a W2 working width. The barriers do not move under impact, but high vehicles may tilt after striking the barrier, so a measurement of this is made. In-situ concrete barriers have varying levels of containment, but their working width is universally low. This categorises them in terms of containment and working width. Applicationsīarrier systems in Europe have to be tested in accordance with EN1317. They are currently used in the central reservation of motorways and major roads where separation of traffic is of prime importance. Their design life is in excess of 50 years. Sophisticated linkage systems mean long runs of barrier can be achieved where deformation under impact is not an issue and pre-cast systems can be used in semi-permanent or permanent situations.īy contrast, in-situ concrete barriers are completely rigid and permanent. Pre-cast barriers are also used in tidal flow and temporary traffic control situations. At the end of the contract, the barriers can be taken to storage or delivered to the next site. Pre-cast barriers are ideal for temporary traffic situations such as the protection of the workforce during new construction or major maintenance. The first is factory produced pre-cast systems, whilst the second category is slipformed in-situ barrier systems. With traffic volumes increasing across Europe, road authorities are realising the value of concrete systems in keeping opposing lanes of traffic segregated.Ĭoncrete barriers fall into two categories. There will also be more focus on vulnerable road users, motorcyclists in particular.Ĭoncrete barriers offer enhanced safety and reduced maintenance when compared with other systems such as steel and wire rope. The use of passive safety systems and, more specifically, road restraint systems undoubtedly contributes to higher safety. One of the seven strategic objectives, amongst others such as intelligent vehicles and better enforcement, is safer road infrastructure. That is why the European Commission (EC) has adopted challenging plans to reduce the number of road deaths on Europe’s roads by half in the next ten years. With 39 000 road traffic deaths in 2008 and socio-economic costs of € 180 billion, road safety continues to be a priority area for action in the EU.Īlthough the actions taken so far have been effective in several Member States, the numbers of road fatalities remain unacceptably high. Involvement in a road traffic crash is the leading cause of death and hospital admission for citizens of the European Union under the age of 45 years. In this publication you will find, amongst others, the benefits of Concrete Safety Barriers, the History of Concrete Safety Barriers in Europe, a brief chapter on the European Standards: EN1317, etc. EUPAVE is proud to present the brochure on Concrete Safety Barriers.
