Struktur Perkerasan Pemilihan
UMUR RENCANA
• Pemilihan umur rencana didasarkan pada ….
• Disajikan pada tabel 2.1
• Nilai diluar tabel tersebut bisa diambil, jika ….
• Umur rencana versus/dan Kapasitas jalan
Asphalt Concrete
Bitumen Bitumen + Sand Bitumen + Sand + Aggregate
Cement Concrete
Paste = Cement + Water
Mortar = Cement + Sand + Water
Concrete = Cement + Sand + Aggregate + Water (+admixture + additives)
Flexible pavement
perkerasan lentur Rigid pavement
perkerasan kaku
The essential difference: distribution the load over the subgrade.
less stiff material, small area load distribution,
self healing capacity, smooth wheel-road interaction.
higher rigidity + stiffness, wider area load distribution, rough

Flexible or Rigid pavement?
The type of pavement structure to be selected depends on:
the available materials, climatic conditions,
maintenance philosophy etc.
It is clear that one has to be careful in just copying designs which seem to be effective and successful in other countries.
The local conditions which influence the choice of a
particular pavement type has to be considered.
