Subject	Civil and Structural Engineering
Specific subject area	Calcium bentonite, Sodium bentonite, Road stabilisation, Unbound granular materials, Repeated load triaxial test
Type of data	Table Image
How data were acquired	The dataset was formed by performing Repeated Load Triaxial Test (RLTT) in the laboratory.
Data format	Raw
Description of data collection	Repeated Load Triaxial Tests (RLTTs) were performed according to the standard EN 13286–7. A total of 12 samples was tested considering two types of bentonite (calcium based and sodium based) as stabilizing technologies and two types of aggregates (crushed rocks and natural gravel) as construction materials to be stabilized. 2 replicate samples were tested dried (w = 0%) for each combination. The deformations of the tested samples were assessed using six Linear Variable Differential Transducers (LVDTs).
Data source location	The testing campaign took place at the Department of Civil and Environmental Engineering, Norwegian University of Science and Technology (NTNU), Høgskoleringen 7A, Trondheim 7491, Norway. Aggregates came from local quarries in Trøndelag region, Norway. Bentonite clays were provided by industrial suppliers (see Acknowledgments section).
