Research on Measurement of Aggregate Micro-structure Using Laser and Fractal Theory and the Relationship with Asphalt Pavement Performance of Anti-slide

Based on aggregate micro-structure measurement, combined with fractal theory and frequency analysis, the paper carried out on the road of anti-sliding performance, including the extraction of aggregate indoor micro-structure, the corresponding value of the wear and polishing of raw materials and on-site road aggregate micro-table. We also discussed the morphology based on aggregate micro-structure and properties of anti-slide important relationship, and use artificial intelligence to predict and evaluation and so on. Using high-precision laser texture sensor rapidly acquainted aggregate surface structure, using digital graphic images of the microscopic analyze and calculate fractal dimension. We could assess aggregate with the micro-structure, and through theoretical and practical method to measure a combination of anti-slide projections law with attenuation performance.
