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


Types uses of asphalt materials

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
