The standard Rolling Thin-Film Oven test is: The control system comprises of a microprocessor digital controller and overheat thermostat with calibrated scale and tamper proof lock.

The exterior is constructed from sheet steel finished in an easy clean powder coated paint and the interior chamber is made from stainless steel. The RTFO also provides a quantitative measure of the volatiles lost during the aging process. Asphalt binder is exposed to elevated temperatures to simulate manufacturing and placement aging. The Rolling Thin-Film Oven (RTFO) procedure provides simulated short term aged asphalt binder for physical property testing. Temperature is controlled and pre-set at 163✬ The control system comprises of a highly accurate PID temperature controller and an independent overheat thermostat with calibrated scale and tamper proof lock. Heated by Incoloy sheathed elements positioned in the base of the oven offering natural convection. Two rotating turntables of 13.5in diameter are supplied to perform both tests The unit is well insulated and has a double glazed window to view the test chamber. The interior chamber is made from 304 stainless steel. The exterior is constructed from sheet steel finished in an easy clean powder coated paint.

This dual purpose oven is designed to perform Loss On Heat and Thin Film Test for bitumin and asphaltic materials and complies to the requirements of BS2000 ASTMD6, D1754 & AASHTO T47, T179 Oven trending is displayed for up to 48 hours and optional upgrades are available for alarm outputs. Advanced features can be turned on and off to suit bespoke heating applications and tailored to customer preference. The control system comprises of a bespoke touch screen user interface that offers both accurate temperature control and an integral overheat system by using 2 individual PT100 sensors. Air is then continuously circulated around the chamber with around 15% expelled through the top vent which is replaced with the incoming air. Fresh air is entered into the oven and passed across the heating element and into the chamber. Heated by Incoloy sheathed elements positioned in the either the base or side of the unit. The interior chamber is made from mild steel coated with aluminium (CLAD).įitted with fixed shelf runners and removable chrome plated wire grid shelves.
