Improvement of Mechanical Properties in Flexible Pavement by using Nanotechnology

In Civil Engineering, vast improvement has been achieved through the production of materials with new purposes or by refining the performance of existing ones. Today Nanotechnology is widely considered as one of the 21st century’s important technologies. In this investigation has been trying to use the Carbon Nanotubes as an additive matter for bitumen, technical characteristics of bitumen and asphalt mixtures as well as to promote. Therefore, in this research, parameters such as bitumen’s permeability degree, ductility and marshal stability, and asphalt specific gravity will be investigated. In our research project we will try to increasing Carbon Nanotubes by 1%, 1.5%, 2%.In this regard we will perform laboratory tests such as Penetration Test, Ductility Test, Softening Point Test, and Marshal Stability Test. The use of these mixtures, in addition to improving asphalt surface properties, we will try to decrease thickness of under layers and cause the decreasing of stone materials consumption as well as economical aspect.
