Raw stereo-photogrammetric orthophotos and height maps and pendulum test value (PTV) and Traction Watcher One (TWO) friction measurements from 45 asphalt pavement test sections

This dataset contains orthophotos and height maps of 45 asphalt pavement test sections (20 measurement points each, 900 locations total), reconstructed by stereo-photogrammetry from overlapping images captured with a full-frame camera and macro lens. Each test section is divided into two parts (01 and 02), corresponding to measurement points located before and after a reference steel plate. This plate served as a fixed reference marker for reliable identification of measurement locations during continuous friction coefficient measurements. The rasters have a resolution of 2500 × 1520 pixels and are referenced, with a pixel size of 0.05 mm — covering the 126 × 76 mm area of the pendulum slider contact patch. The height map is the direct photogrammetric reconstruction of the surface as exported from the Structure-from-Motion / Multi-View Stereo pipeline. Data are provided in raw, unprocessed form to allow independent analysis with user-defined filtering, descriptor extraction, and modeling workflows. No filtering, levelling, truncation, or descriptor extraction has been applied. Friction measurements. Pendulum Test Value (PTV, EN 13036-4) and the Traction Watcher One (TWO) longitudinal friction coefficient µ are provided as companion files, semicolon-delimited in a section–position–point ID format (e.g. "01P0101;0.310"). Documentation. The AI model trained on these data, the full training methodology, performance metrics, and the MATLAB analysis code are documented in a separate Zenodo record: https://doi.org/10.5281/zenodo.21247668 Funding.
