-------------------------------------
This dataset contains data collected for the investigation of moisture diffusion in aged bitumen and the ageing kinetics in the presence of moisture.

It is being made public both to act as supplementary data for publications and the PhD thesis of Lili Ma and in order for other researchers to use this data in their own work.

The data in this data set was collected in the Pavement Engineering Laboratory of the Delft University of Technology between 2022 and 2023.

This research project was made possible by a grant from the China Scholarship Council (CSC).

-------------------------------------

All the results were performed in the equipment Dynamic vapor sorption. Detailed settings of drying methods, testing temperatures, and relative humidity can be obtained in the raw files.

For files starting with "3", which describe moisture diffusion in aged bitumen, Q460, T710, T1015, T1620, and V710 represent different bituminous binders. 20P, 40P, 80P refer to 20, 40, and 80 hours of PAV ageing. "80%" is the measuring relative humidity. "60mg" refers to sample mass. "C" represents temperature.

For files starting with "6" and "7", which describe ageing kinetics in the presence of moisture, "RH" denotes relative humidity, "Dry" denotes 0 relative humidity, "air" represents using air as carrying gas, and "nit" represents use nitrogen as carrying gas.

For details regarding post processing and analysis, readers are referred to the paper "Thermodynamics and kinetics of moisture transport in bitumen" and the PhD thesis "Interactions of moisture and oxidative ageing mechanisms in paving binders: towards improving durability of pavements"
