QUALITY CONTROL METHODS ADOPTED FOR RIGID PAVEMENT CONSTRUCTION AT A DEFENCE AIRFIELD

This paper describes in detail the quality control measures for concrete used for the rigid pavement construction of India's longest runway. It considers: (1) the design of the mix formula; (2) the production of the concrete; (3) the transportation and placement of the concrete; (4) quality control at the site; (5) testing in the field laboratory; and (6) the significance of the test results. For usual concrete work, the 'average method' is used, where test beam samples are cast from a slab, and tested after 28 days of curing. For mass concreting work for runways, the authors decided to use a statistical quality control method, because: (1) it is more realistic; (2) it indicates general trends in quality variations; and (3) it sometimes reveals unexpected causes of variation in quality. The chance of rejection of a slab is very much less if the statistical method is used than if the average method is used. When the average method is used, great care has to be taken with the concrete production and with the preparation and transport of beam moulds.
