Summary: One polymer-modified bitumen PMB 25/55-60 was tested in two stages: original and after the modified Thin-Film Oven Test (TFOT). The time ranges from 1h-5h, and temperatures from 120°C-200°C were used. The Fourier-Transform Infrared (FTIR) Spectroscopy and Dynamic Shear Rheometer (DSR) with parallel plates were conducted. Test temperatures range from 30–70°C for a 25 mm diameter plate and 0–30°C for an 8 mm plate with 10°C intervals and angular frequency range of 0.1, 1.0, and 10 Hz.

This research was conceptualised and developed as part of activities related to project No. 2021/03/Y/ST8/00079, funded by the Polish National Science Centre (NCN), under the Weave-UNISONO 2021. The dataset was used for analyses for the journal paper titled "Investigating the ageing process of polymer modified bitumen using a modified Thin-Film Oven Test in the aspect of recycling purpose", which is available on http://dx.doi.org/10.7409/rabdim.023.020
