Why Tire rubber modification is needed?

• Total crumb rubber volume generated in CA:

• 42 million PTE

= 504 million lb = 252,000 Ton

• Total Crumb rubber used in CA Paving:

• 3.5 million PTE

= 42 million lb = 21,000 Ton

• Total Crumb rubber going to CA landfill:

• 5.3 million PTE

= 63.6 million lb = 31,800 Ton

• Caltrans proposal to use 5% tire

rubber in all conventional grade

bitumen will eliminate all crumb

rubber still going to the landfill

PTE: Passenger Tire Equivalent1 PTE = 12 lb = 5.45 kg of crumb rubber

Common type of crumb rubber modifications

• Dry Process• Specific mixes/gradation. The crumb rubber is added to a heated

aggregates and combined materials are mixed with the bitumen.

• Field Blended Wet Process• Specific mixes/gradation & chip seal. Crumb rubber, extender oil and

bitumen are blended in a reaction vessel. Crumb rubber specifications

requires the use of larger mesh size and high natural rubber

• Terminal Blend Rubber Binder• Utilized in any type of gradation such as gap graded, dense graded (with

RAP also), open graded, porous pavement, chip seal, emulsion & cutbacks. Utilize 100% crumb rubber. Polymer can be added depending on agency

specifications. TBRB is PG graded due to high solubility.

• TBRB utilize:

– 100% crumb rubber

– Locally derived tires• CA derived tires

– Passenger &/or Truck

– 30 – 40 mesh

– Ambient or cryogenic • No fiber• No metals

– Other additives if needed

What are we talking about?

• The crumb rubber is reduced to

micron size

• Have similar mix/comp temp as

conventional

• Standard mix design – Marshall– Hveem– SuperPave

• Comes ready to use upon arrival to

hotplant

• Easy for contractor to incorporate in

their mixing & construction process

• Easy for agencies to incorporate in

their current PG grading

Summary of Fatigue Lives of Flexible Pavements with Neat and Terminal Blend Binders

•The fatigue life of a fle xible pavement constructed with a terminal blend HMA mi xture is 2.5

times the fatigue life of a flexible pavement constructed with a neat HMA mixture.

•The fatigue life of a fle xible pavement constructed with a terminal blend WMA mi xture is 23

times the fatigue life of a flexible pavement constructed with a neat WMA mixture.

•The use of Sasobit as a WMA additive with the neat asphalt binder reduced the fatigue life of

the flexible pavement 9 times.

•The use of Sasobit as a WMA additive with the terminal blend asphalt binder did not impact

the fatigue life of the flexible pavement.

Preliminary summary of the Interlayer Shear Strength of the HPS and SS-1h Tack Coats.

Visual Observations

In addition to the measured ISS values of the HPS and SS-1h tack coats, the following visual observations were

made:.

•The samples treated with the SS-1h tack coat experienced complete separation of the bottom and top lifts after

testing.

•The samples treated with the HPS tack coat did not experience any separation between the bottom and top lifts after

testing. The Pult was determined as the peak load from the load versus time curve.

Testing Setup for the Interlayer Shear Strength

ISS = [Pult/(πD2/4)]

where;

ISS: interlayer shear strength (psi)

Pult: ultimate load applied to specimen (lb)

D: diameter of specimen (in)
