DOWSETT'S MINI CONCRETE PAVING TRAIN AUGERS WELL AT LEEDS AIRPORT

Following problems on a trial run with a full scale sgme paving train, an american-built allen auger paver has been used as part of the train replacing the main compactor/ finisher and diagonal finisher. The smaller train was more suited to the seven-day curing time on the 604 m long 45.7 M wide extension to the airport runway. In the machine, the two lower faces of a triangular space frame are plated with angle iron to form a double-edged tamp carrying a series of closely spaced high frequency piston vibrations on leading and trailing edges. Concrete is levelled out by the auger before the advancing rows of vibrators. The hard aggregate used in the pavement quality concrete has had an abrasive effect on some components, but Dowsett claims that the machine has performed the equivalent of two years work. Initial trials indicate good compaction down to 350 mm, although the runway extension was constructed in a 300 mm single pass slab. Hundreds of cores taken from the slab are said to be within the required tolerance and the surface regularity is within the specified plus/minus 3 mm over a 3 m length. (TRRL)
