1 Asphalt BinderTypes and Uses 1 Types & Uses of Asphalt Materials HMA Surface

2 Asphalt BinderTypes and Uses 2 + HMA (Hot Mix Asphalt)

3 Asphalt BinderTypes and Uses 3 Bituminous Materials Asphalt Tar Asphalt Cement EmulsionCutback (from petroleum crude) (from coal)

4 Asphalt BinderTypes and Uses 4 Trinidad Lake Asphalt

5 Asphalt BinderTypes and Uses 5 Asphalt Binder is Generally Produced in a Refinery

6 MEDIUM DISTILLATE FIELD STORAGE PUMPING STATION LIGHT DISTILLATE HEAVY DISTILLATE PROCESS UNIT ASPHALT CEMENTS FOR PROCESSING INTO EMULSIFIED AND CUTBACK ASPHALTS STILL AIR BLOWN ASPHALT STORAGE TOWER DISTILLATION REFINERY RESIDUUM OR GAS PETROLEUM SAND AND WATER CONDENSERS AND COOLERS TUBE HEATER Source of Asphalt Cement Oil Well (Gasoline) (Kerosene) (Diesel Oil)

7 Asphalt BinderTypes and Uses 7 General Asphalt Binder Properties Adheres well to most rock Waterproof Fairly durable Resistant to reaction with most acids, alkalis, and salts Temperature sensitive

8 Asphalt BinderTypes and Uses 8 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

9 Asphalt BinderTypes and Uses 9 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

10 Asphalt BinderTypes and Uses 10 Asphalt concrete Asphalt paving mix Asphalt mix Asphalt Hot Mix Asphalt (HMA) Bituminous concrete Bituminous paving mix Bituminous mix HMA = Asphalt concrete = binder + aggregate Used mainly for hot mix pavement surfacing

15 Asphalt BinderTypes and Uses 15 Cutback Asphalts Rapid Curing (RC) Asphalt + Naphtha Surface Treatment RC - 30 RC - 70 RC RC Medium Curing (MC) Asphalt + Kerosene Stockpile Patch Prime Coat MC - 30 MC - 70 MC MC Slow Curing (SC) Asphalt + Oil SC - 70 SC SC SC

16 Asphalt BinderTypes and Uses 16 CUTBACKS - USES Rapid Curing –Tack coats –Surface treatments Medium curing –Prime coats –Stockpile patching materials –Road Mixing Operations Slow curing –Prime Coats –Stockpiling –Road mixing

17 Asphalt BinderTypes and Uses 17 EMULSIONS - USES Slow Setting (SS) –Tack coats, fog seals, dense-graded cold mixes Medium Setting (MS) –Open graded cold asphalt-aggregate mixtures Rapid Setting –Surface treatments
