constructed using 8 rigs. Trackway The Royal Engineers use a variety of aluminium and fabric systems that can be joined to form a trackway, enabling rapid deployment and recovery of temporary roads and reinforced surfaces for existing roads, easing the movement of heavy and tracked vehicles, and reducing damage on the ground. Some can be laid by hand or by machine, however, the heavier aluminium versions are laid with specialist mechanical equipment. Class 30 Trackway The Class 30 Trackway can be laid in 15 minutes either from a 4 tonne truck with Launching and Recovery Equipment or from a Medium Wheeled Tractor with a Hydraulic Dispenser. Recovery is by hand onto the 4 tonne LRE or hydraulically using the "Beach Dispenser". Class 70 Trackway The Class 70 Trackway is made of heavy aluminium planking, with each roll of trackway weighing 2.4 tonnes. Rolls can be launched mechanically using plant equipment or by hand. The planking is attached together by fradrick along the sides. Recovery is by hand or using the Medium Wheeled Tractor (MWT) and beam dispenser. Logistic Trackway (Mammoth Mat) The Logistics Trackway is in rolls 30m long, 4m wide and weigh 1.8 tonnes which can be man handled into position and are only suitable for wheeled vehicles. They also can not be used in sandy conditions. See also British Army Royal Engineers Modern equipment of the British Army References Military bridging equipment equipment United Kingdom
