During testing, a contant load (0 to 450 g) is applied to a asphalt beam for a selected duration.

The deflection of the beam is measured and monitored continiously by PC. Further the test parameters are set by the PC, which displays & prints a plot of load vs. deflection and calculates the stiffness at the lowest temperature anticipated.

For tests acc. ASTM D 6648 an auxiliary cooler is required to cool down the molds, so that the sample is stiff enough to be demolded without distortion.
