Rheological Properties and Anti-Icing Performance of Asphalt Modified with Hydrophobic and Salt-Storage Components
Description
This dataset contains the experimental data supporting the manuscript “Rheological Properties and Anti-Icing Performance of Asphalt Modified with Hydrophobic and Salt-Storage Components”. The data include the screening results of hydrophobic and salt-storage materials, contact-angle and conductivity measurements, rheological test results obtained from temperature sweep, frequency sweep, MSCR, BBR and LAS tests, response-surface and multi-objective evaluation data, and mixture-scale anti-icing test results including ice accumulation, freezing temperature and apparent ice-pavement shear strength. The dataset is provided to support the reproducibility and verification of the results reported in the manuscript.

Steps to reproduce
The dataset contains the raw and processed experimental data used in the associated manuscript. Hydrophobic and salt-storage materials were first screened using contact-angle, ice-melting, apparent-loading and conductivity tests. Modified asphalt binders containing different dosages of hydrophobic and salt-storage components were then evaluated using contact-angle, conductivity, temperature-sweep, frequency-sweep, MSCR, BBR and LAS tests. Response surface methodology and entropy-weight-based multi-objective evaluation were used to compare formulation-dependent responses. At the mixture scale, Control, hydrophobic-only, salt-storage-only and composite-modified asphalt mixtures were evaluated using ice-accumulation, surface-water freezing-temperature and apparent ice-pavement shear tests. Detailed specimen preparation, test conditions, equipment and calculation procedures are provided in the associated manuscript. The spreadsheets contain the numerical data used to generate the corresponding figures and tables.
