Figure A 2: Examples of marginal cases of prepared granular pavements

~2616751

~8219634

  • Hard and dense surface.
  • Some variability in surface texture/finish but mostly uniform.
  • Hard, tight surface. Aggregate visible.
  • Highly variable surface texture.

~9082693

~3494937

  • 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.
