micro-XRCT data sets of a stone mastic asphalt drill core before and after a uniaxial compression test (sample 2): sample 2-3

The compression test was performed by controlling the displacement with the following procedure: Starting the measurement at a contact load of 10 N, where the displacement is set to 0 mm. Increasing the displacecment to 0.1 mm (strain around 0.14 %), with a speed of 50 mm/min. Holding the displacement at 0.1 mm for 300 s.

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. 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. 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".
