The unit has been developed to simulate the accelerated ageing of bitumen and bituminous binders after 5 to 10 years. The sample is exposed to high pressure and temperature for 20 hours, to simulate the effect of a long time oxidative ageing by verifying the penetration and softening ...
VDO removes air bubbles created during the in-service oxidative ageing of asphalt binder by the PAV. VDO Feautures include: 3 operating modes: Fully Automatic, Semi-Automatic and Manual. Temperature is measured by Platinum RTD. Over temperature limit switch. Automatic release of the pressure ...
