摘要
This paper is about a kind of asphalt crack self-healing material upon exposure to UV light. In this work, the OXE-CHI-PUR networks self-healing agent are synthesized by the photocatalytic-based chemical method. It is a kind of asphalt crack self-healing material upon exposure to UV light. Fourier transform infrared spectroscopy is used for characterization of the self-healing agent. TG analysis shows self healing agent has good thermal stability. Beside, this paper reveals the repair mechanism, validation and studies the influence of self-healing agent on the properties of asphalt. The result shows that this OXE-CHI-PUR network preferably synthesized self-healing agent for road materials. Self-healing agent can improve the low-temperature property, construction property and anti-aging property of asphalt. But high-temperature property of the asphalt has slight effect.
