Pine’s 125X, G1, and G2 Superpave Gyratory Compactor mold assemblies all use this 150-mm Mold Base Plate.

Proper Mold Base Plate Orientation

The picture displays the 150-mm mold base plate upside down to show the pocket (the dull spot in the center of the plate).  The mold base plate is in the mold properly when the pocket faces the ram foot and the smooth surface faces the asphalt material.

The Impact of an Improperly Oriented Mold Base Plate

  • Installing the mold base plate upside down, the pocket towards the asphalt and the smooth face towards the ram foot, will cause the height measurements to be incorrect leading to higher density and lower air voids in a specimen.
  • Excess lubricant and debris between the ram foot and the mold base plate with no pocket to escape into may impact the angle of gyration, which may affect specimen density.

The Purpose of the Pocket

  • A pocket allows space for excess grease and debris to collect.
  • A pocket offsets the impact of a crowned ram foot.
