Pine’s 100-mm Mold Top Plate is included with 100-mm Mold Assemblies for the Pine 125X Superpave Gyratory Compactors. Pine’s G1 and G2 Gyratory Compactors do not require top plates with their molds. The Pine GB1 Gyratory Compactor does not compact 100-mm specimens.
Proper Mold Top Plate Orientation
The mold top plate is correctly placed in the mold when the pocket and the beveled edge face the ram foot and the smooth surface faces the asphalt material.
The Impact of an Improperly Oriented Mold Top Plate
- Installing the mold top plate incorrectly with the pocket towards the material may cause the plate to bind against the mold and reduce the amount of pressure applied to the asphalt material. This may affect specimen density.
- Installing the mold top plate incorrectly with the smooth face towards the ram foot may impact the angle of gyration if excess lubricant or debris are present. This may affect specimen density.
The Purpose of the Beveled Edge
The beveled edge prevents binding between the mold top plate and the mold wall when the angle of gyration is induced during compaction.
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.
No Pocket in Your Mold Top Plates?
Pockets can be machined into existing mold top plates that do not have pockets.
