Abstract

One of the conductive fiber types used in the mixtures in order to provide the desired performance by reducing the deterioration of asphalt concrete coatings during the project is steel fibers. In recent years, studies on the use of steel fiber to provide self-healing property by heating the layers during the repair phase have attracted attention. In order to evaluate the economy of steel fiber layers, it is necessary to know the mechanical properties of these layers before they come into repair. In this study, the abrasion made Marshall design to binder mixtures, according to the design result, at the rate of 0.1%, 0.15% and 0.2% of the total weight of aggregate and bitumen, a steel fiber of 10 mm length and 1 mm diameter was added to the mixtures. After the first Marshall stability, conditioned indirect tensile strength tests on the mixtures, the same tests were applied again without removing the samples from the device. As a result, the highest Marshall stability and conditioned indirect tensile strength were obtained in binder mixes with 0.10% steel fiber compared to the unadulterated, while in the additive wear mixture tests, close to the additive-free or lower results were obtained.
