ABSTRACT The vast amount of waste materials such as polyester waste fibers accumulating throughout the world is creating costly disposal problem. The use of these materials was proved to be economical, environmentally and effective in increasing the performance properties of the asphalt mixture in new years. The main objective of this research was to determine whether homogeneously dispersed waste polyester fibers improve Marshall stability and rutting resistance of asphalt concrete mixtures containing various lengths and percentages of the fiber. The experimental design included the use of available aggregates, and polyester waste fibers as additives to enhance the properties of asphalt mixtures. Two fiber lengths of 1cm and 2 cm were used with four different fiber contents of 0.2%, 0.35%, 0.50% and 0.65 by weight of total mixture. The results of the experimental work presented in this paper suggested that, in general, the addition of the polyester fiber s was beneficial in improving both the stability and rutting resistance of the modified asphalt mixtures. | ||
