Principal component analysis of rheological and hardening data from bituminous binders

Danish Road Institute has started a project where rheological profiles of bituminous binders (in three stages: original, RTFOT and PAV material) are measured by DSR in the temperature range of 30-100°C. Traditional binder tests are also collected. To evaluate the hardening behaviour and/or addition of different modifications, infrared spectroscopy (IR-spectra) is used on the same samples to deliver a “chemical” profile.
