To construct the highly durable pavement which has a sufficient resistance to plastic flow is very important in airport asphalt pavements，because the pavement has to support approximately 400tf of aircraft weight. It is effective for this case to use the asphalt mixture that has a high stability in the surface course and/or binder course，and one of promising mixtures is the large stone asphalt mixture，which has continuous grading with maximum size of more than 25 mm.
　In this paper，applicability of the large stone asphalt mixture in the surface course of airport asphalt pavements was evaluated by carrying out laboratory tests and field loading test. In the laboratory tests，the direct tension test and the cyclic bending test were also conducted in addition to standardized mixture tests. The experimental pavements were constructed and a loading cart with same weight of B-747 type landing gear was used in the field test.
　From the discussion of test results，the following conclusions were obtained.
1)Plastic flow resistance of the large stone asphalt mixture is considerably higher than that of ordinary surface mixture.
2)Fatigue resistance and tensile strain at failure of the large stone asphalt tend to be somewhat below those of ordinary surface mixture at low temperature.
3)The large stone asphalt mixture can be applied in surface course as the durable surface material if the maximum size of aggregate is about 30 mm.
