- Angular surface provides a kneading action as it passes through the grooves
- Tapering flat surface at the back of the plates provides a smooth finished surface
- Confined mixing action manipulates aggregates to reduce air voids and increase density while creating a more uniform surface texture
- Optimized aggregate structure promotes surface temperature uniformity for more consistent compaction
- Enhanced structural integrity minimizes roller shoving for better smoothness
- Increased stiffness strengthens unconfined edges, promotes better joint matching
