|a Flaky aggregate is normally avoided in bituminous mixtures because it influences the aggregate gradation, reduces interlocking characteristics and due to that it should be therefore limited. This thesis presents a study of laboratory evaluation on the effects of flaky aggregates in asphaltic concrete, AC14. Three types of proportion flaky aggregates in the mixture were considered under this study which 8 percent, 16 percent and 24 percent. Laboratory Marshall Mix Design System was used for all mix design. The objective of this study is to study the effect of flaky aggregates on the optimum bitumen content and Marshall Properties of AC14. Flow and stability (ASTM D 1559-89) test was used in this study to determine the value for all parameters needed. It is found that bitumen content will increase with increase the proportion use of flaky aggregates in the mixture. Besides that, the value of Marshall Properties for AC14 such stability, VTM and stiffness are reduced with increase the flaky aggregate content while, the value of flow and VFA is increased. As a conclusion, the presence of flaky aggregate is affected the asphalt content and Marshall Properties for AC14 mix.
