NRC 210
Rotating cylinder ageing test for bitumen (RCAT method)
STANDARDS
EN 15323
SCOPE
This test method is intended to measure the ageing affect of heat and air on a moving film of semi solid asphaltic material in the environment conditions
MAIN CHARACTERSTICS
The standard test conditions adopted are : 500 g of binder, oven heated up to 85 °C, oxygen flow rate of 4.5 L per h, and a rotation speed of 1 rev./min. At predetermined intervals, 25 to 30g of binder is sampled for characterization tests.
The control board includes electronic temperature controller with digital display and setting at 85 °C ± 0.1° for RCAT or 163 °C± 0.5 °C for RTFOT, two factory calibrated flow meters for adjusting oxygen flow at 4500 ml/min ± 500 ml for RCAT and 4000 ml/min ± 200 ml air flow for RTFOT. An electronic safety valve prevent from blowing oxygen into the cylinder while operating above 100 °C. The oven has built in horizontal carriage to hold one stainless steel sample cylinder rotating at 1 rpm for RCAT or 5 rpm for RTFOT. It is equipped with air and oxygen jets for blowing into the cylinder. A stainless steel roller is inserted in the sampling cylinder through the front opening to distribute the binder into an even film on the inner wall during rotation.
