The modern road network is of the most important requirements of the present life. The filler is regarded as one of its major components, and it has great importance in the mixture. When improving its properties and specifications, the hot mixing properties of the asphalt mix are improved . The results of the tests conducted for this research showed that the addition of 1.5% H.L to the control mixture led to a significant increase in the stability of Marshall and air voids, with a rise in (20.4 and 7%), respectively, with an increase in the optimum asphalt content. Moreover, the increase in the tensile strength ratio (TSR) was at the same rate and amounted to 13.6% when compared to the control mixture. The mixtures containing cement kiln dust also led to an increase in the stability of Marshall and air voids. The most significant increase was when replacing it by 50% (23.5 and 6%), respectively, with an increase in the asphalt content. The ratio of indirect tensile strength to tensile strength when CKD is 25% and 50% increases by (6.4% and 12.3%) respectively. These properties deteriorate when the cement kiln dust content increases or hydrated lime increases. |
