Asphalt softening point test has global method and Kesha’s method, zusätzlich zur deutschen DIN, die internationale allgemeine Verwendung der globalen Methodenbestimmung. daher, Unser Land verwendet auch die globale Methode als Standardmethode für den Erweichungspunkttest. Zu den Faktoren, die den Erweichungspunkt beeinflussen, gehört die Wasserbadtemperatur, Wasserbadzeit, Heizrate testen, Testmethode, usw. Das Ergebnis des Erweichungspunkts wird von der Temperatur beeinflusst. Erste, die Anfangstemperatur, wenn die Temperatur hoch ist, has basically no effect on the thick and hard asphalt, and the result is small for the soft asphalt. Zweite, the heating speed, the heating speed is fast, the result is large, and the other is small.

Softening point test sample preparation is very important, special attention should be paid to the process of mold making, scraping process of tiny details to ensure that the sample preparation meets the requirements, in the brushing of the spacer, the isolation layer can not affect the release, and can not make the spacer occupy the space of the asphalt sample, and the selection of the scraper and the control of the heat of the scraper, is an empirical technology. It is necessary to ensure that there are no defects in the softening point sample after the scraping die maintenance.

Tipps: When liquid is added to the beaker of the tester, do not turn on the machine for dry test, the instrument power line should have a good grounding end, the instrument in the test process, the speed of the mixer should be adjusted to the appropriate position, when heating, the speed of the mixer can be faster, when the water temperature is close to the softening point (then the bitumen sample under test begins to drum out), the speed of the mixer should be adjusted to very slow. Even stop the rotation, so as to ensure the accuracy of the test results.
