2.2.1. The Anchored System Installation The Defender 100LDS™ has been tested on 150mm asphaltic concrete over / 150mm granular subbase. The system is anchored to the road surface using two steel ground anchor pins, each 30mm x 500mm, in every second barrier to a maximum of 9.15 metres between anchor locations. -
Page 11: Installation Termination And Crash Cushions
Crash cushions can be used for both uni-directional and bi-directional traffic flows. The TAU- II® crash cushion has been crash tested for use with the Defender 100LDS™ system. Figure 2.2 below shows the TAU-II® crash cushion. The connections and transition details can be found within Appendix B. -

2.3.1. Point of Need The tested length of Defender 100LDS™ is twenty (20) barrier segments or 78.0m. The TAU-II end terminal is a Non-Gating re-directive terminal which establishes the length of need location at the nose of the TAU-II end terminal. If an installation is to be less than 78 m, contact Safe Barriers for further advice. -
