چکیده مقاله
The link between aggregate gradation and asphalt mixture performance has been recognized since asphalt mixtures were first used Almost all of HMA properties are affected by aggregate gradation of the mix In this study, type 4 and 5 mid limit gradations of Iran Highway Asphalt Paving Code were chosen and adjusted by Bailey method An excel spread sheet was developed so that time was saved in calculations Optimum bitumen content for each mix was determined, using Marshall method Experiments of Marshall Stability and dynamic creep revealed that mixtures using Bailey method gradations were improved, both in Marshall and creep properties
