Project Background:
The modern traffic with high volume, heavy load and vehicle channelization causes premature problems such as potholes, cracking and raveling on the asphalt pavement. Therefore, the performance of existing asphalt pavement materials needs to be further improved to meet the increasingly harsh service environment requirements. As an emerging carbon-based material, graphene has been used as an important nano-filler to improve the service performance of asphalt materials due to its unique two-dimensional structure, high mechanical strength and high specific surface area.
Aims & Goals:
1. To develop a preparation technology of hydrocarbon-based graphene modified asphalt admixture with cross-scale and precise regulation of composite structure.
2. To development the preparation technology of low-cost large-scale graphene modified asphalt materials and investigate the effects of graphene properties, content, structure and interface configuration on the properties of asphalt and its mixture.
3. To establish the structure-activity relationship of ‘composite configuration-mechanical properties- multifunctionalization-long-term service’ and realize the engineering demonstration application of graphene asphalt mixture.
