✦ Synopsis

Visbreaker and straight-run bitumens with the same commercial characteristics were produced in a refinery from four topping residues, in order to study the influence of the visbreaking process on the behaviour of bitumens. Besides the conventional standard tests, road tests and differential scanning calorimetry (DSC) were employed. Differences in temperature susceptibility, oxidation resistance, melting characteristics and glass transition temperature TG were measured. Such differences are not revealed by the routine tests.

A simple and quick test method was developed to distinguish thermally cracked materials, especially visbreaker residues and bitumens, from untracked products, such as straight-run distillation bitumens and residues. The method is based on the reactivity of thermal residues and bitumens with phosphor
