Method for Determining the Sensitivity to Oxidation of a Bituminous Binder by Electron Spin Resonance
27 Jan 22
This invention concerns a method for analysing the ageing stability of a bituminous binder, in particular by reference to its susceptibility to oxidation, by analysing a sample of the bituminous binder by means of electron spin resonance and measuring the integral of the signal of the carbon-centred stable radicals; accelerated ageing of the bituminous binder, comprising: i) heating the bituminous binder, followed by ii) heating the bituminous binder resulting from step i) under pressure; analysing a sample of the aged bituminous binder obtained from step b) by means of electron spin resonance and measuring the integral of the signal of the carbon-centred stable radicals; and comparing the integral of the signal of the carbon-centred stable radicals of the bituminous binder obtained from the first step and that obtained from the previous step.
