oven ini menunjukkan perkiraan perubahan sifat aspal selama pencampuran panas konvensional sekitar 150 ℃ seperti yang ditunjukkan oleh viskositas dan pengukuran reologi lainnya. Ini menghasilkan residu yang mendekati kondisi aspal seperti yang tergabung dalam trotoar. Jika suhu pencampuran cukup berbeda dari 150 ℃ tingkat. lebih atau kurang efek pada properti akan terjadi. Oven ini juga dapat digunakan untuk menentukan perubahan massa, yang merupakan ukuran volatilitas aspal

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.
