Operating Instructions for the Asphalt Softening Point Tester
Place the metal ring onto a glass plate coated with a glycerin-talc powder separator (glycerin : talc = 2:1). Heat the bitumen (for petroleum bitumen, heat to ≤ the estimated softening point + 90℃; for coal bitumen, heat to ≤ the estimated softening point + 50℃), then pour the heated mixture—after thorough mixing and sieving—into the metal ring, slightly higher than the surface of the ring.
