|Abstract:||The size effect of specimens, 4-, 5-, and 6-in. in diameter, of asphalt mixtures on the resilient modulus, indirect tension and Marshall tests was studied. Four asphalt mixtures (B1 mix, Airport, W3 and W6 mixes) with different top stone sizes were used. The effect of the ratios of the specimen diameter to top stone size were determined for the resilient modulus and the indirect tension test. A trend suggested that 5- and 6-in. diameter specimens give more realistic values of tensile strength and stiffness for mixes using large stones (larger than 1-in.). When larger diameter specimens are used, the results obtained from the resilient modulus and the indirect tension test are more representative of the behavior of the mixtures.|
