Abstract

With the continuous development of national construction and the increasing investment in road construction, the research of road materials has become a major research hotspot in road construction. The rise of nanomaterials provides new ideas and possibilities for this. Carbon nanotubes are currently the most potential and valuable road composite nano-reinforcement. In this article, through the analysis of high-strength iron wire-like carbon nanotube materials, the vibration compaction characteristics of road composite materials doped with carbon nanotubes are studied. This article proposes that the doped carbon nanotube material in the road composite material, through different doses of doping, testing and observing the strength of the material, so as to study its vibration compaction characteristics. The vibration frequency and compaction density and porosity value of the road composite material doped with carbon nanotubes are measured, and the main factors affecting the compaction effect are analyzed, which affects the compaction effect of the carbon nanotube road composite material flow and compactness factors under. Experimental results show that the compressive strength of road composites doped with multi-walled carbon nanotubes has increased significantly, an increase of 46.8% MPa year-on-year. Under the same carbon nano-content, as the particle size increases, the density of the composites is more or less will grow with it.
