JSP has worked with MIRA, ‘the UK’s only full scale aerodynamic wind tunnel’, to test and further develop our road safety products.
The Safety at Street Works and Road Works: Code of Practice require barriers to withstand BS8442 Class C and Class B winds. Working with Mira we have been able meet these requirements and in some cases exceed them. It has also given us the raw data and insight to develop new products designed to offer the maximum wind stability possible.
Class C
Barriers must be capable of withstanding class C winds (31 km/h) blowing from any direction. The code suggests it may be necessary to use ballast or cross-bracing as a means to achieve stability.
Class B
In Scotland, there is a further requirement: Barriers must be capable of withstanding winds of class B (63km/h) blowing from any direction, where a site is unattended for 24 hours or more.
The Safety at Street Works and Road Works: Code of Practice
Code of practice to help utility companies and highway authorities carry out signing, lighting and guarding of street works and road works. The code of practice applies on highways and roads, except all motorways and any dual carriageways with a speed limit of 50 mph or more.
We have developed two products to fit with our barriers -SureFoot Bloc™ and SurePole™.
The SureFoot Bloc™ is a heavy duty recycled PVC foot weighing 6.5kg. Adding weight to a barrier rather than the traditional use of sandbags.
The Surepole™ telescopic stability poles can be added to the Frontier® Cross-Link® barrier to increase wind stability by bracing two barriers together or attaching it to a Surebloc™.
We perform testing on barriers including the Surefoot Bloc™, SurePole™ and without.
JSP is committed to improving the design and manufacture of road safety products worldwide through the innovation of intuitive products and investment in the latest manufacturing processes and state-of-the-art machinery.
