基于感应加热的融冰除雪抗滑罩面性能劣化机理及抑制方法研究

基于感应加热的沥青抗滑罩面具有路面养护、融冰除雪及自愈合等功能，但其在融冰除雪过程中所面临的性能劣化问题阻碍了该材料的应用。本项目以该抗滑罩面为研究对象，研究因融冰除雪导致的层间抗剪失效、沥青膜剥落及冻胀损伤等问题的形成机理，并提出相应的性能劣化抑制方法。首先，采用有限元模型模拟温度场，结合微米CT扫描方法，研究层间接触状态劣化机理并总结层间抗剪性能失效性为。然后，采用偏光显微手段，研究水对高温沥青膜的细观侵蚀机制，总结沥青膜粘附性能的衰减规律。同时，使用CT扫描探究空隙水冻胀导致的结构损伤机制，发展结构疲劳规律。最后，提出基于层间抗剪性能的材料优化设计方法，并研究决定沥青膜剥落及结构损伤的材料关键参数，寻求基于参数协调的感应加热耦合调控方法，提出抗滑罩面性能劣化抑制方法。研究成果对解决感应加热沥青路面的性能劣化问题具有参考意义和研究价值，助推融冰除雪抗滑罩面的实际应用工作。

The asphalt anti-skid cover based on induction heating has the functions of road maintenance, ice and snow melting and self-healing. But its performance deterioration in snow and ice melting process is an obstacle to the application of this material. This project takes the anti-skid overlay as the research object, studies the formation mechanism of interlayer shear failure, asphalt film peeling and frost heave damage caused by snow and ice melting process, and puts forward the corresponding performance deterioration inhibition method. Firstly, the finite element model was used to simulate the temperature field. Combined with the micron CT scanning method, the deterioration mechanism of interlayer contact state was studied. Then, by means of polarized light microscopy, the meso-erosion mechanism of water on high-temperature asphalt film was studied, and the attenuation law and failure threshold conditions of adhesion performance of asphalt film were summarized. At the same time, this project intends to explore the mechanism of structural damage caused by frost heave and the law of structural fatigue damage. Finally, the material optimization design method based on the interlayer shear performance was proposed, and the key material parameters determining the asphalt film spalling and structural damage were studied. The induction heating coupling control method based on parameter coordination was sought, and the performance deterioration inhibition method of the anti-skid overlay was proposed. The research results have reference significance and research value to solve the performance deterioration problem of inductively heated asphalt pavement, and the practical application of the anti-skidding overlay surface can be promoted.
