BITUMINOUS MIX DESIGN CONSIDERATIONS IN TURKEY

In this study, both Marshall and Indirect tensile test equipment was used in order to find a relationship between these equipments. Specimens were prepared using Marshall mould and standard Marshall compactor. In order to determine the optimum bitumen content for each grading of granular materials three samples were prepared for each bitumen content. The samples were then tested by Marshall test equipment. After having determined the optimum bitumen content the samples were then prepared according to the optimum bitumen content. Fatigue and plastic deformation test were then carried out on the samples. Samples were then prepared for 5% optimum bitumen content. It was seen that the longer fatigue life was obtained at the optimum bitumen content as compared with the other samples. Therefore, designing the mix with Marshall equipment test results guarantee the longer fatigue life. However, as the Marshall equipment test results does not give any information about plastic deformation life, using indirect tensile test equipment for the determination of plastic deformation helps to develop better bituminous mixtures.
