Utility of Aramid, Polyolefin and Polypropylene Combination in Hot Mix Asphalt as a Fiber Material

Fibers are very useful for improving the strength of the hot mix asphalt mixtures. However, the homogenous distribution in the mixture is an important factor of the usability. Therefore, a combination of aramid, polyolefin and polypropylene is used in the market. The polyolefin fibers in the combination are used to ensuring the homogenous mixture. In this study, the utility of the fiber combination in hot mix asphalt as a fiber material is examined. Therefore, the fibers are added into the mixture in three different rates (1, 3 and 5‰ by weight of the mixture). Firstly, the optimum binder rates are determined, and the specimens have been tested for the indirect tensile strength and tensile strength ratio values in accordance with the modified Lottman test. As a result, fiber-reinforced mixtures have less moisture susceptibilities than the reference mixture.
