The drill core was scanned with identical scanner settings before ("reconstructed_20200505_01.tar.gz") and after ("reconstructed_20201016_01.tar.gz") a uniaxial compression test.

The sample had a diameter of 75.33 mm and a height of 70.64 mm before, respectively a diameter of 76.71 mm and a height of 67.40 mm after the compression test (measured by caliper). The asphalt mixture is a stone mastic asphalt with a nominal maximum aggregate size (NMAS) of 11 mm (SMA 11 S). It contains diabase aggregates and a 50/70 bitumen binder. The material is described in detail by <a href="https://doi.org/10.1007/s11709-017-0407-9">Hu et al. (2017)</a>.<br><br>
The compression test was performed by controlling the displacement with the following procedure:<br>
<ul>
<li> Starting the measurement at a contact load of 10 N, where the displacement is set to 0 mm.</li>
<li> Increasing the displacecment to 0.1 mm (strain around 0.14 %), with a speed of 50 mm/min.</li>
<li> Holding the displacement at 0.1 mm for 300 s.</li>
<li> Increasing the displacement by another 0.1 mm (strain around 0.14 %) to 0.2 mm (strain around 0.28 %), with a speed of 50 mm/min and holding it for 300 s.</li>
<li> Repeating the procedure of adding displacements 0.1 mm increments (strain around 0.14 %), until the maximum load of 3.7 mm (strain around 5.24 %) is reached and held for 300 s.</li>
</ul>
During the test, time (s), distance (mm), and load (N) were logged at regular intervals and can be found in "2_3_compression_test_data.csv". A visualization of the test procedure is shown in "test_procedure.pdf".Image dataThe material is a stone mastic asphalt with a nominal maximum aggregate size of 11 mm (SMA 11 S).
