Sample Asphalt Binder Contents. ... Each sample is then heated to the anticipated compaction temperature and compacted with a Marshall hammer, a device that applies pressure to a sample through a tamper foot (Figure 1). Some hammers are automatic and some are hand operated. Key parameters of the compactor are:

Standard Test Method for Marshall Stability and Flow of ...

4.1.3 Marshall flow is a measure of deformation (elastic plus plastic) of the asphalt mix determined during the stability test. In both types of failure, the Marshall flow is the total sample deformation from the point where the projected tangent of the linear part of the curve intersects the x-axis (deformation) to the point where the curve starts to become horizontal.
