# Data repository

## Content

This repository consists of data of different Dynamic Shear Rheometer tests (DSR) using different bitumen materials.

The stiffness behavior was examined using a temperature-frequency sweep, and the deformation behavior was examined using an adapted Single Stress Creep Recovery (SSCR) test. 
These tests were carried out on Anton Paar's DSR utilizing the plate-plate geometry. 
The Anton Paar DSR was also employed to assess fatigue and low-temperature behavior, utilizing a solid-sample geometry.

The output is stored in Hierarchical Data Format ([HDF5](https://www.hdfgroup.org/solutions/hdf5/)).
[HDF5](https://www.hdfgroup.org/solutions/hdf5/) files can be accessed by software tools like [HDFView](https://www.hdfgroup.org/download-hdfview/) or coding languages, e.g. Python using package [`h5py`](https://docs.h5py.org/en/stable/index.html).
