Design Practices

Stages of design:

  1. Evaluate surface texture;
    • Sand Patch Method
    • Visual Texture Analysis
  2. Evaluate traffic conditions: volume, speed, etc.;
  3. Evaluate climatic and seasonal characteristics;
  4. Evaluate and select type of chip seal;
    • Single Chip Seal
    • Double Chip Seal
    • Racked-in Seal
    • Cape Seal
    • Inverted Seal
    • Geotextile-Reinforced Seal
    • Sandwich Seal
  5. Evaluate aggregate selection;
    • Maximum particle size—gradation shows 10mm maximum
    • Overall gradation—one-size, uniformly graded
    • Particle shape—cubical or pyramidal and angular (one fractured face of 70%)
    • Cleanliness—less than 2% passing the 75 µm sieve
    • Toughness to abrasion—abrasion not to exceed 30%
  6. Determine binder application rate.
