The impact of using three contents 1, 3 and 5 % nano CaCO3 on the composition asphalt binder mechanical properties Hot Mix Asphalt (HMA) wearing course was studied. Laboratory tests were performed to examine physical rheological characteristics nanomodified binder. In addition, Superpave Indirect Tensile Test (IDT) conducted evaluate mechanistic moisture susceptibility HMA. test findings pointed that modified with 5% CaCO3, decreased temperature sensitivity due stiffening improved resistance permanent deformation. Additionally, HMA mixture performance exhibits a substantial increase in moduli value at temperatures varying from 40 oC increased flexibility lower testing as compared neat mixture.
