This article summarises the main points of presentation about the use of concrete block paving for aircraft pavements made by john emery at the annual conference of the aerodrome owners association, jersey, September 1988. Concrete aircraft pavements are prone to cracking and when overlaid with asphalt this may also crack and will in addition be susceptible to attack from fuel and oils. The author suggests that this is an ideal application for concrete blocks and describes trials carried out at Luton international airport. The properties required of an aircraft pavement are listed and include durability, strength, rapid drainage of surface water and rapid repair. Concrete blocks are found to have many attributes of conventional pavements without some of the disadvantages, e.g. Curing time, joints. Concern that jointing sand might be removed by jet blast has been overcome by the use of a low viscosity polymeric binder. During resurfacing at Luton the load classification number (lcn) of the concrete blocks was assessed and found to have increased the pavement lcn by 14%. The Federal aviation administration's flexible design method has been modified based on experience at Luton and research by emery and knapton so that 80 mm concrete blocks bedded on 50 mm sand may replace the 125 or 140 mm asphaltic material specified.
