Full Function Pave (FFP)

region provides water blocking functionality. An asphalt finisher system equipped with an
improved compactor works the pavement to a longitudinally-grooved coarse finish, which
contributes to greater driving safety during rain and other adverse weather conditions,freezing and noise reduction, and visibility improvement. FFP paving also has a data-proveneffect of traffic accident reduction.

Longitudinally grooved, coarse-surface hybrid paving(FFP) ‫ﺗﻌﺒﯿﺪ اﻟﻄﺮق اﻟﻤﺘﻜﺎﻣﻞ اﻟﻮظﺎﺋﻒ‬‫ﺗﻌﺒﯿﺪ اﻟﻄﺮق اﻟﻤﺨﺘﻠﻂ ذو اﻟﺴﻄﺢ اﻟﺨﺸﻦ اﻟﻤﺜﻠﻢ‬Features The single top layer provides both water drainage and water blocking functionality
 Hydroplaning reduction and other safety improvement benefits
 Visibility improvement and road noise reduction achieved by the longitudinallygrooved coarse surface
 Longitudinally grooved coarse finish also contributes to a longer-lasting anti-freezing effect Longer pavement life due to resistance to aggregate scattering Skidding minimization as part of traffic accident reduction measures
Water drainage
The surface region of the Full Function
Pave layer has water drainage
functionality which reduces floating wateron the road surface during rain and otherwet conditions. Such floating water
reduction helps minimize hydroplaning
and water spraying (“smoking”) effects,
contributing to greater driving safety
during rainfall. Floating water reduction
also reduces freezing in wintertime andthus helps prevent “black ice” fromforming on the road.

GranularpavingFFPFreezing reduction
Longitudinally grooved coarse roadsurface, a main feature of the Full
Function Pave, retains antifreezing agent
well, contributing to good salt retention
and thus a longer-lasting antifreezing
effect. Such greater salt retention makes
the road surface more quickly exposable
compared to ordinarily paved roads. Inaddition, the smaller amount of salt loss
to outside the road boundary allows
winter road networks to be maintainedwith a fewer number of antifreezer
applications.

Shown in the diagram is a fatigue destruction test
result where the specimen was loaded at a single
point with both ends supported. Comparison offatigue resistance between Full Function Pave andgranular asphalt composition shows that Full Function
Pave has approximately ten times as much resistanceof a straight asphalt 60/80 binder composition andalso twice as much fatigue resistance as that of TypeII polymer improved asphalt.

The high-strength PRC panel is a paving precast (factory-fabricated) concrete component with long life, highquality and greater durability, making the pavement suitable for heavy loading applications such as airports,
container yards, and busy highways and soft and weak ground conditions and also significantly reducing
work time and the lifecycle cost of the road.

Features Uses high-strength concrete composition (with design
criterion strength of 60 N/mm2).
 Adoption of the lattice truss steel reinforcement structure
contributes to greater displacement conformability, wall
thickness reduction and weight cut.
Panel connection with a cotter joint Inter-panel connection with cotter joints realizes a fully flat
joint and facilitates partial replacement of panels.
