Radlock Composite Carriageway & Footpath System
SLIDE 2 Radlock Highway Systems Introduction
Although current methods are used across the Industry, these can represent:-
Hazard to both workers and members of the public Removal by vandals especially footpath boards. Cost of replacing footpath boards or steel road plates if they are stolen With steel road plates – cost of repeated anti skid coating renewal No Heavy Lifting equipment required – Simple 2 Man Lift using Manhole Keys. Securing the boards with nails or screws could end up with:
- expensive cutback on reinstatements
- replacement boards
- injuries to members of the public
This method reduces plant, labour and material costs all in one system
National Grid have granted the Radlock acceptance for use (Best Practice)

Radlock Carriageway & Footpath System
Almost 33,000 people get hurt each year walking on the British roads with Falls on Public Footpaths Pedestrian accidents can be avoided. It goes without saying that most of the pedestrian accidents taking place all over the world are caused because of negligence. The injuries caused by faulty footpaths could range from minor bruises to near fatal ones where a person may possibly even lose their life after falling in a deep, open excavation. Injuries caused due to the pavement fall:- Foot injuries Ankle injuries Knee Injuries Back and Neck injuries

Advantages of Radlock:
Robust construction from steel / coated steel legs and norel 6 grade plastic make it durable and hard wearing Quick & Easy to use - simple lock and key mechanism using a standard ‘T’ bar or box key carried by the majority of utility contractors Can be used in any ground type.

SLIDE 5 Advantages of Radlock:
Secure - Once in place it cannot be removed without the key Versatile design for use in excavations
(bespoke designs available) Detaches from board to allow easy stacking when not in use.

The brief - Quick win in reducing congestion QWIRC3
SLIDE 7 Transport for London (TfL) encourages the use of plates to reduce congestion in the capital and other areas of the U.K. They have recently invested over £1million to find a solution for covering excavations, through trials at TRL. (please see TFL website – QWIRC3) When tested road plates needed to be capable of safely supporting a load of 5.75tonnes single wheel load. Any locking mechanism would also need to withstand these loads and directional force in
- rder to maintain a good contact with the road surface at all times. The Radlock Series 15
can withstands this load, and after 65,000 passes there were no signs of any fatigue on the Radlock Locking mechanism.

TRL Product tested on Transport Reserach Laboratory test rig and track
Transport for London have granted the Radlock Carriageway System approval for use across the TLRN.
The ONLY composite carriageway system approved for use by TfL for road crossings, linear trenches and core & vac uses across the TLRN.

- National Grid - Plating Workshop
- Adrian Wathen (Best Practice Engineer)
Adrian Wathen of National Grid has extensively worked towards reducing congestion by utilising existing technology of modular road plates and doing so without the necessary heavy plant that is usually required with heavy steel road plates when delivered and fixed to the road surface. Using Industry experts at Transport Research Labs to assist with the test programme, the testers settled on 4No. Independent tests: PTV skid resistance test 40Kn Central point load test Ultimate Load Test Cyclic load test based on standard axle load

Radlock – helping National Grid (Core & Vac)
During our work with National Grid and the development and supply of a safe workable solution to the problem of open excavations in footpaths and carriageways we were asked to assist in the implementation of a safe working solution for when the Core Vac Excavation System is deployed. A problem occurred with the existing ‘Night Plates’ used to cover the temporary holes when an core drilled hole had been created and required covering . The existing Night Plate system was not secured, and this resulted in an accident when a bus containing passengers travelling over the plate was damaged as the plate lifted and caused significant damage; to the Bus and the Night Plate.

- National Grid ordered several Radlock Carriageway Systems recently in order to alleviate the problem of
plating over Core & Vac holes should the need arise.
- This has reduced the weight of the Core & Vac vehicles as less boards are required due to the configurations of
the Radlock System.
- This has also reduced labour time spent when leaving the site as the board and lock is deployed in less than a
minute.
- Radlock System has also reduced congestion, as holes were sometimes left open due to the unsafe fixing of
the ‘night plates’ and Heras fencing erected around the hole with traffic lights to control traffic flow around the opening.
