bitumen 85/25
Bitumen 85/25, characterized by its sol structure, undergoes a semi-hardening process through vacuum fractionation under oxidation or air blowing. This involves passing air through heated bitumen to achieve the desired viscosity, resulting in a flexible yet non-flowing bitumen at ambient temperatures. The air-blowing process modifies viscosity, leading to variations in equilibrium.
