Critical assessment of new polymer-modified bitumen for porous asphalt mixtures

Construction and Building Materials, 2021
New experimental polymer-modified bitumen with a high-vinyl content polymer was fabricated for porous asphalt (PA) mixtures. The bitumen with maximum stability was achieved using storage stability, gelation criteria and physical bitumen tests.

Impact of molecular structure of PP on thermo-rheological properties of polymer-modified bitumen

Construction and Building Materials, 2021
Polymers have been widely used to improve the performance of bitumen. Polypropylene (PP), one of the most common plastomer for bitumen modification, is utilized specially in roofing application adding up to 30 wt% to bitumen.
