3 REJUVENATORS Why You Need To Use Them Fact is Liquid AC cost hit $ in California in Dec/10 Fact is Liquid AC cost hit $590 plus in California in Dec/11 Fact is Liquid AC cost hit $560 plus in California in Dec/12 Fact is Liquid AC cost hit $590 plus in California in Dec/13 How long will your agency wait before implementing a preservation program?

4 Any agency can implement the use of Rejuvenators by simply deferring a small amount of resurfacing.

5 KNOW YOUR LIFE CYCLE COSTS INPUTS FOR CITY STREETS HMA Rejuvenator= $16,000 per mile (Lasts 3-5 years) HMA Chip Seal = $33,000 per mile (Lasts 5-7 years) HMA Milling and Overlay = $187,000 per mile (Lasts years) HMA Full Depth Reconstruction = $550,000 per mile (Lasts 20 Years) A 500 mile Local Road Network has a current worth of $175,000,000! (And some say that is a low number)

20 Are typically engineered cationic emulsions containing maltenes, saturates (light fractions) and possibly modified with asphalt and polymer The primary purpose is to soften the stiffness of the oxidized AC pavement surface and co-mingle or hydrate with the asphalt binder to extend the life of the pavement surface by adjusting properties of the AC mixture. Maximum absorbance of the rejuvenator is expected.

21 What is a Rejuvenating Seal? Are typically engineered cationic emulsions containing maltenes, saturates (light fractions) and possibly modified with asphalt and polymer The primary purpose is to soften the stiffness of the oxidized AC pavement surface and co-mingle or hydrate with the asphalt binder to extend the life of the pavement surface by adjusting properties of the AC mixture. Maximum absorbance of the rejuvenator is expected.

22 WHAT IS AN ENGINEERED ASPHALT REJUVENATOR EMULSION? Asphalt consists of two main fractions: asphaltenes which are the hard brittle component, insoluble and not affected by oxidation and the highly reactive subfractions: maltenes These maltenes are oily and resinous in appearance

23 Criteria for a Rejuvenator? Penetrate Contain Maltene Fraction AND Replace Lost Maltene Fraction Flux with Binder to Adjust Viscosity & Penetration Values

25 What is a MALTENE BASED REJUVENATOR? PC + A 1 S + A 2 Replace the Lost Maltene Fractions

32 The loss of the liquid asphalt oils the maltenes in the upper 3/8-1/2 of the asphalt pavement begins the deterioration process.

33 Reactive components deteriorate causing an imbalance with the asphaltenes. The loss of the liquid asphalt oils the maltenes in the upper 3/8-1/2 of the asphalt pavement begins the deterioration process.

34 Measuring the Aging Process Binder aging is measured by checking Viscosity and Penetration values. Viscosity- How fluid the oil is Penetration- Softness

35 Measuring the Aging Process Penetration numbers go down Asphalt cement hardness goes up

36 Measuring the Aging Process Penetration numbers go down Asphalt cement hardness goes up

37 Measuring the Aging Process When viscosity goes up. Asphalt cement hardness increases & pavement flexibility goes down

38 Measuring the Aging Process When viscosity goes up. Asphalt cement hardness increases & pavement flexibility goes down

39 Measuring the Aging Process The Result A Failed Glue

41 Benefits of an Asphalt Rejuvenator:

42 Benefits of an Asphalt Rejuvenator: 1 Increases penetration value of the asphalt cement in the top portion of the pavement which extends the pavement s lifecycle. 2 Seals pavement against intrusion of air and water, thereby slowing oxidation, preventing stripping and raveling and protects the pavement in-depth. 3 Increases the durability of the asphalt in the top portion of the pavement by improving the chemical composition of the asphalt cement.

43 Where and When to Use a Rejuvenating Seal? Construction seal to new asphalt pavements. Rejuvenating seal to pavements to extend pavement life before the use of a wear course seal is required. To correct pavements exhibiting minor segregation, raveling, poor compaction. Note: A rejuvenating scrub seal should be considered on pavements exhibiting more distress than a straight maltene rejuvenator seal could address.
