this oven indicates approximate change in properties of asphalt during conventional hot-mixing ar about 150℃ as indicated by viscosity and other rheological measurements.it yields a residue which approximates the asphalt condition as incorporated in the pavement.if the mixing temperature differs appreciably from the 150℃ level. more or less effect on properties will occur. this oven also can be used to determine mass change,which is a measure of asphalt volatility
KN-2872 Rolling Thin Film Oven
Overview
KN-2872 Rolling Thin Film Oven is designed on the requirements of the instrument according to ASTM D2872 Standard Test Method for Effect of Heat and Air on a Moving Film of Asphalt (Rolling Thin-Film Oven Test). This oven is used to indicate approximate change in properties of asphalt during conventional hot-mixing at about 302℉(150℃) as indicated by viscosity and other rheological measurements. It yields a residue which approximates the asphalt condition as incorporated in the pavement. If the mixing temperature differs appreciably from the 302℉(150℃) level, more or less effect on properties will occur. This test method also can be used to determine mass change, which is a measure of asphalt volatility.
