Proper Mold Base Plate Orientation
The picture shows the mold base plate upside down to display the pocket (the dull spot in the center of the plate). Properly orient a base plate in the mold by having the pocket on the surface facing away from the asphalt material.
The Impact of an Improperly Oriented Mold Base Plate
- Installing the mold base plate upside down, the pocket towards the asphalt, causes height measurements to be incorrect. This leads to higher density and lower air voids in a specimen.
- Excess lubricant and debris beneath 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 helps maintain a consistent internal angle of gyration by …
- Allowing space for excess grease and debris to collect.
- Offsetting the impact of a carriage base (125X) or crowned ram foot (G1 and G2).
