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.

16.  Softening point -VG10/30/40 – 40/47/50⁰C
 Pavement Temp. = Amb. temp. + 20 ⁰C
 Bleeding of Surface, Rutting, Creeping
 Softening Point of PMB

PMB (Adv) – 85⁰C

17.  Cracking – Fatigue, Ingress of water
 Fraass Breaking Point
VG10/30/40 – (+) 4/6/8⁰C
PMB120/70/40 – (-)24 / (-)18 / (-)12 ⁰C
PMB (Adv) – (-) 21 ⁰C

18.  PMB reduces cracks at low temp.
 It completely seals the surface.
 Better adhesion of binder with aggregate. Reduces
stripping.
 Longer life.

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
