general asphalt binder properties
General Asphalt Binder Properties
  • Adheres well to most rock
  • Waterproof
  • Fairly durable
  • Resistant to reaction with most acids, alkalis, and salts
  • Temperature sensitive

Types and Uses

slide8
Asphalt Components

Asphalt binder is broken down into 3 components:

  • Asphaltenes
    • Dark brown friable solids
    • Control viscosity and adhesive properties
  • Resins
    • Dark solid or semi-solid
    • Greatly affected by temp.
    • Disperse the asphaltenes
  • Oils
    • Colorless or white liquids
    • Oxidize and harden into asphaltenes and resin molecules

* These three components are Blended to produce asphalt binder of desired properties

Types and Uses

asphalt types used in pavement
Asphalt Types Used in Pavement
  • Asphalt cement (asphalt binder)
      • Used for HMA, patching
  • Asphalt emulsion (residue + water + emulsifying agent)
      • Used for cold mix & maintenance applications
  • Asphalt cutback (residue + solvent)
      • Used for cold mix & maintenance applications

Types and Uses

hot mix asphalt hma
Hot Mix Asphalt (HMA)
  • HMA = Asphalt concrete = binder + aggregate
    • Used mainly for hot mix pavement surfacing
  • Asphalt concrete
  • Asphalt paving mix
  • Asphalt mix
  • Asphalt
  • Bituminous concrete
  • Bituminous paving mix
  • Bituminous mix

Types and Uses

cutback asphalts
Cutback Asphalts
