The rolling thin-film oven test (RTFOT) method determines the resistance to hardening of asphaltic materials, bitumen or bituminous binders under the combined effects of heat and air.
UTB-0340A-T
UTB-0340A-T Bitumen Oven uses the rolling thin-film oven test (RTFOT) method to determine the resistance to hardening of semisolid asphaltic materials/ bitumen or bituminous binders under the combined effects of heat and air.
The Internal chamber of the UTB-0340A-T Bitumen Oven is insulated with fiberglass or similar, is made out of stainless steel, and has a door with a a symmetrically located window.
The oven has a programmable temperature controller which has a digital display system and works in PID mode. The oven uses a temperature sensor instead of the ASTM 13C thermometer. The digital unit on the oven displays the temperature and the temperature can be controlled by a mechanic switch on the oven. Conforming to the CE Directives.
Air Compressor and Air-Drying Unit (UTGE-3572) should be ordered separately. Maximum pressure should not exceed 2 bar when an air compressor is used.
The Bitumen Oven for RTFOT is supplied complete with;
UTB-0345-T
UTB-0345-T Bitumen Oven can be used to measure two different things, and uses two different methods to do so. Firstly, it is used to measure the loss in mass of oil and asphaltic/bituminous compounds by using the loss on heating test method. Secondly, it is used to measure the effect of heat and air on semi-solid asphaltic/bituminous materials with the thin film oven test (TFOT) method.
The internal chamber of the UTB-0345-T Thin Film Bitumen Oven is made of stainless steel and the door has a panel window.
The oven has a working temperature ambient to 200ºC , a digital PID controller and a circulation fan.
Rotating shelf and sample cups should be ordered separately according to the test type.
