AI Technical Summary
Existing technologies cannot effectively distinguish the contributions of asphalt film stripping and aggregate polishing to pavement texture and skid resistance, and the lack of spatial correspondence in multi-stage test data leads to inaccurate skid resistance evaluation and insufficient interpretability.
By employing a fusion technology of fluorescence tracer imaging and three-dimensional point cloud scanning, a unified in-situ positioning benchmark is established through positioning and calibration molds. Combined with U-Net segmentation model and three-dimensional point cloud data matching, automated zoning and quantitative characterization of asphalt and aggregate areas are realized, and a pavement skid resistance performance prediction model is constructed.
It improves the accuracy and interpretability of pavement skid resistance performance evaluation, reduces repeated positioning errors, enhances the spatial consistency and comparability of multi-source data, and strengthens the independent characterization ability of asphalt and aggregate regional texture parameters.
