• 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

Mix Type Additive Asphalt Binder Fatigue Life
Grade Type ESALs Ratio
HMA None PG64-22 Neat 1,629,000 --
PG64-28TR Terminal Blend 4,114,000 2.5
WMA Sasobit PG64-22 Neat 174,500 --
PG64-28TR Terminal Blend 4,052,000 23.0
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)
