micro-XRCT data sets of a stone mastic asphalt drill core before and after a uniaxial compression test (sample 2)

The drill core was part of a large drill core (sample 2), taken from a test track by the "Intstitut of Highway Engineering (ISAC)" at the RWTH Aachen and subsequently cut into three parts (sample 2-1 to 2-3) by the "Institute of Urban and Pavement Engineering" at the Technische Universität Dresden (TUD) for further analysis.

This data set contains two micro X-ray Computed Tomography (micro-XRCT) data sets resulting from region of interest scans (diameter 58.32 mm, height 46.06 mm) of the center region of a stone mastic asphalt (SMA) drill core. The drill core was scanned with identical scanner settings before ("reconstructed_20200429_01.tar.gz") and after ("reconstructed_20201015_01.tar.gz") a uniaxial compression test. <br><br> The sample had a diameter of 75.12 mm and a height of 70.93 mm before, respectively a diameter of 78.05 mm and a height of 67.11 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 load with the following procedure:<br> <ul> <li> Starting the measurement at a contact load of 10 N.</li> <li> Increasing the load to 500 N (stress around 0.11 N/mm²) with a speed of 100 mm/min.</li> <li> Holding the load at 500 N (stress around 0.11 N/mm²) for 600 s.</li> <li> Increasing the load by another 500 N (stress around 0.11 N/mm²) with a speed of 100 mm/min and holding it for 600 s.</li> <li> Repeating the procedure of adding load in 500 N (stress around 0.11 N/mm²) increments, until the maximum load of 5000 N (stress around 1.13 N/mm²) is reached and held for 600 s.</li> </ul> During the test, time (s), distance (mm), and load (N) were logged at regular intervals and can be found in "2_1_compression_test_data.csv". A visualization of the test procedure is shown in "test_procedure.pdf".<br><br> NOTE: It turned out that the specimen top and bottom surfaces were not exactly plane-parallel which led to an non-uniform transmission of the load, which lead to a first full-surface contact between the load plate and top surface of the specimen when the 1500 N load increment was reached.
