Manufacturer of road blockers, bollards and vehicle barriers, ATG Access, has launched its Populus Bollard system which is designed for ridge protection. It is the second bridge security system the company has brought to market.
The new solution is claimed to be the shortest, shallowest and the slimmest solution making it ideal for bridge applications.
The system achieved both the IWA 14 and PAS 68 standards during tests undertaken at the MIRA testing facility in March 2020, and was able to arrest a 7.5-tonne vehicle traveling at 30mph at a 30 degree angle.
The tests simulated the distinctive features of a vehicular attack on a bridge and resulted in minimal penetration damage of under half a metre. Bridge design dictates that vehicular attacks are most likely to be carried out at a shallow angle, as a forward moving vehicle leaves the carriageway to mount the pavement at speed.
Bridges bring specific challenges to security systems such as drainage requirements, expansion joints and depth constraints. Coupled with the inability to close structures for prolonged installation periods, bridge security systems need to operate within strict parameters while delivering robust performance.
Designed for installation within areas with either no depth available or a challenging substructure, the system requires excavation of just 40mm and is installed without bolting, mechanical fixings or any upstand. Furthermore, it requires no finishing surface treatment to the highway to conceal the top of the product.
