Figure A 2: Examples of marginal cases of prepared granular pavements
| |
- Hard and dense surface.
- Some variability in surface texture/finish but mostly uniform.
| - Hard, tight surface. Aggregate visible.
- Highly variable surface texture.
|
| |
- Aggregate visible and mostly uniform.
- Windrow of excess fine particles swept from the surface resulting in bony and coarse surface finish.
| - Isolated lamination (adjacent to pen) and pockets of tearing of the surface.
- Aggregate still visible with mostly uniform texture.

Figure A 3: Examples of poorly prepared granular pavements
| |
- Slurrying of fines on the surface.
- Non-uniform, soft uneven surface.
- Not level with adjacent kerb and channel.
| - Scabbing and excess fines on the surface.
- Non-uniform texture.
|
| |
- Tearing and delamination of surface after sweeping.
- Non-uniform surface finish.
| - Non-uniform surface finish/texture.
- Scabbing and tearing of the surface.
- Uneven drying indicates non-homogenous material.
