ARMY & PRIVATE VEHICLES on PERMATRACK SURFACING

PERMATRACK ROAD OVERLAY

Still resisting heavy armoured tanks after 12yrs wear & tear

PERMATRACK HM Road Surfacing material was laid as a 40mm thick overlay protection layer on a Dorset County Road in 1998. The intention was to  prevent the destruction of normal road surfacing whenever the  British Army tracked vehicles [Which have to pass over this public road, as part of their driver training programme]

A 40mm thick road surfacing, that can resist a nominal 60 tonne tracked vehicle [like a centurion tank] that is stopped at a halt sign, on an incline, awaiting to turn sharp right, with a learner driver at the controlls, has to be tough. If after eleven years use, with thousands of such vehicles exerting very high shear stresses and still the 40mm thick surface is in very good condition. This material has to be very, very, good.

PERMATRACK HM being a HAPAS CERTIFICATED MATERIAL is one of the toughest materials  available

Permatrack is ideal for long lived highway /Overlays / Inlay crack repairs / High stress areas such as Road junctions /Round abouts.

Large road areas, including bridge decks, maybe machine layed to exacting tolerances over varies types of  WPM

PERMATRACK HM INLAY REPAIR TAKES THE STRAIN

‘PERMATRACK HIGH MODULAS’  Inlay crack repair system was the preferred material chosen to permanently repair a cracked major trunk road in the  HIGHWAY AGENCY’s MACS Area 7.

This high stressed road [A1] requires the toughest of products to effect a long lived repair to the ‘live’ longitudinal crack that is located in the wheel track area. No compromise on quality of materials or workmanship was allowed. The specified inlay crack repair system must be HAPAS approved. Have been previously tried and tested on several of the UK’s most exacting motorways for a number of years past. Ultra heavily trafficked roads such as  M4  Heathrow junctions-Contract -14 kilometers of longitudinal cracks. Which we routed out to a profile of 320mm wide x 140mm deep, and this section was fully trafficked within 1 hour of completion. Other contracts RAB have completed include the M6 / A1[M] / T junctions / London’s Waterloo roundabout. These completed contracts are just a sample of PERMATRACK HM inlay crack repairs  RAB have completed over the past 9 years.

RAB offer the Extrusion of various kerb sections throughout the UK.These continuous kerbs can be installed to meet the designer requirements and criteria, ranging from a straight line to the more complex of curves.  RAB kerbing is suitable for both Highway or Landscape situations. They are all completed with minimum disruption and maximum choice of profile, colour or texture.

Heavy duty kerbs can be steel reinforced and dowelled onto the base structure in order to prevent vehicle dis-lodgement of finished kerbs.

To prevent traffic nudging installed kerbs

Twin steel tendons are fed into the casting chamber in a continious line

LANDSCAPE areas including /shrubberies / flower beds / trees /ponds etc are completed with minimal disturbance. Mowing machinery is allowed to cut right upto the kerb profile without damage to machine or kerb.

No curve is too dramatic for us to follow

Permatrack HM joints are suitable to be overlaid with any new thin surfacing during planned highway maintenance

giving economic and aesthetic advantages over other jointing systems 

Minimal future joint replacement costs

No added traffic management costs

Fast open programmes achieved

Smooth ride for all traffic conditions

Deck joint surfaces match adjoining surface

Same skid resistance as main surfacing

Suitable for most surfacing specifications

Reduce the whole-life-costing of your asphaltic plug joints from an average of 8 years to 12 years, saving over 35% on your maintenance costs. The Permatrack Heavy Duty Bridge Expansion Jointing System is manufactured using the same Permatrack high modulus material that meets the BBA Agrément (HAPAS) Certificate number 02/H072.

The busy A55 Chester to Bangor trunk road, along the pretty North Wales Coast, takes a constant stream of heavy goods vehicles to and from the sea port ferry at Holyhead. As well as being a major tourist route, this road has to take local industrial traffic.

Many of the inspection chambers, which have been sited in the wheel track area, require constant re-bedding in order to prevent the dislodged, loosened cover and frames from becoming a safety hazard. These repairs require carrying out every 18 to 24 months and Conwy County Borough Highways Department obviously considered this too often! Therefore, they called in RAB Associates to advise, design and specify a cost-effective, long-term solution. Keep reading »
