2. PMB in wearing course can increase life of
pavement by 50 – 100%.
Cost of road increases by 1.5 – 2.5% by using
PMB in place of conventional bitumen.
Cost of PMB is 25% - 40% more than that of
conventional bitumen.
3. Asphalt reinforcement interlayer(ARI) is a
combination of Glass Grid and Stress
Absorbing membrane interlayer(SAMI).
Use of ARI can increase the Axle passes by 2
to 5 times.
Cost of ARI is equivalent to 15mm to 25mm of
Bituminous concrete.

29. Reinf material – high tensile strength (100 KN)
Made of glass fiber with polymer coating
Self adhesive & recyclable
Arrests reflective cracks
Increases axles passes by 2 to 5 times
Ideal for joints along widening of pavement
Cost ≡ 15 to 25mm of Bituminous concrete
Glasgrid ®
37. Adulteration of Bitumen
Initial cost vs Life Cycle Cost
Funds ? Reduce length, Not Quality
Item of Work – BOQ Specs ? (ER, Softening
point & Viscosity)
PMB - Elastomeric vs Plastomeric
38.
39. Modification without High Shear Mixer,
Curing, Monitoring of quality including
Viscosity
≡
Adding Crumb Rubber / Polymer as filler
in Pug mill of hot mix plant
43. Flexible pavement preferable to rigid
- Life Cycle Cost, QA, Skid resistance
- Repair during operations
Pavement life is extended with the use of
PMB (Adv) & ARI
44. Better adhesion, rut/creep /fatigue
resistance Longer Life.
Suitable in all climatic conditions
Environment Friendly - Saves Minerals,
Binder, Fuel, Human Resources
