First UK Install of New P4 Terminal

Highway Care, working in partnership with InterRoute Area 2, has supplied the first UK Xtension 110 P4 terminal along the M4.  Installed by Barrier Services, the new P4 terminal was chosen by InterRoute Area 2 for use on a maintenance contract for the Highways Agency. 

The Xtension 110 is currently the only universal handed D1.1, P4 system available and offers many advantages to contractors and installers.  The Xtension 110 can be connected to W2, W3, W4 and W5 barrier systems which include ‘W’ beam and Open Box Beam barriers.  Options include socketed posts and surface mounted posts, while the system is made up of fewer parts than other similar systems.  Therefore installation can be carried out quicker, reducing stock requirements and repair costs.

The Xtension 110 is fully tested to EN1317- 4 and is fully approved for use on Highways Agency roads. Under test, the system proved its capability to redirect a 1500kg vehicle, when a side impact occurred, safely redirecting the vehicle at a shallow exit angle and also absorbing the energy from a 1500kg vehicle impacting ‘head on’ at up to 110km/h.  When impacted, the system engages with the impacting vehicle, influencing deceleration and direction of the errant vehicle, bringing it to a safe halt.  This compares favourably with a conventional ramped end which can potentially launch errant vehicles into the obstruction being shielded or into an adjacent carriageway.  Its overall length and low displacement make it particularly suitable for restricted sites.
