PAVING AT SPEED

A description is given of the design and operation of the prototype blaw know BK106 tracked paver being used to lay a wearing course on the RN27 improvement project in Brittany. The fully hydrostatic tracked paver has high flotation and extra traction which gives the equipment an advantage over wheeled pavers where roads are being constructed on softer, less stable bases. The machine has a minimum basic width of 2.5 M making it suitable for smaller road projects. Extensions can be bolted on so that it can lay mats up to 8 M wide. The screed control on the machine can operate with most base and wearing course materials including crusher-run stone and dry lean concrete. Although the machine has a maximum laying capacity of 750 T/H, the BK106 was operated at 200 T/H on the project described due to limitations in delivering the volume of mix required to the site.
