Stone Mastic Asphalt Drill Core Micro-XRCT Scans Before and After Compression

Two micro X-ray Computed Tomography scans capture a 58.32 mm diameter region of a stone mastic asphalt drill core before and after a uniaxial compression test. The dataset includes detailed test procedure data logging time, distance, and load at regular intervals. Matthias Ruf from the University of Stuttgart created this data to study material deformation.

Use Cases

• Analyze 3D microstructural damage in asphalt based on pre- and post-compression X-ray CT scans
• Model material behavior under load based on the detailed stepwise compression test procedure
• Validate computational simulations of asphalt mixtures using the provided physical test data
• Study aggregate-binder interface failure in stone mastic asphalt based on the 11 mm nominal maximum aggregate size specification

Strengths

• Provides paired, high-resolution 3D scans of the exact same sample region before and after a destructive test
• Compression test procedure is documented in detail with specific load steps, speeds, and hold times
• Sample material composition is specified with diabase aggregates and a 50/70 bitumen binder, linked to a peer-reviewed publication

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Last update date is unknown; freshness unverified
