Accelerated ageing protocols for (polymer modified) PA to obtain representative (rheological) properties, mimicking field aged materials
conference paper
In this work ageing protocols for asphalt and mastics were developed and investigated; i.e
representation of the field ageing and their acceleration degree. Here it was aimed to age laboratory
prepared specimen analogous to naturally aged materials in the field and compare their material
properties. Such simulation of ageing is of importance in order to potentially specify and objectively
assess the properties of (novel) binders and asphaltic materials for Porous Aaphalt (PA). Hence, two
ageing protocols were developed and investigated; one ageing protocol for asphalt mixtures and one
for asphalt mastics. The rheological (DSR) properties of binders from the laboratory aged materials
have been evaluated in comparison to binders from field aged specimen.
