Lapisan Pondasi Bawah (Subbase Cour

Lapisan Pondasi Bawah (Subbase Course)
Lapis pondasi bawah adalah lapisan perkerasan yang terletak di atas lapisan tanah dasar dan di bawah lapis pondasi atas.

Lapis pondasi bawah ini berfungsi sebagai :

Bagian dari konstruksi perkerasan untuk menyebarkan beban roda ke tanah dasar.
Lapis peresapan, agar air tanah tidak berkumpul di pondasi.
Lapisan untuk mencegah partikel-partikel halus dari tanah dasar naik ke lapis pondasi atas.
Lapis pelindung lapisan tanah dasar dari beban roda-roda alat berat (akibat lemahnya daya dukung tanah dasar) pada awal-awal pelaksanaan pekerjaan.

The Foundation Layer Of The Bottom (Subbase Course)Foundation tier roughness layer bottom is located above a layer of ground base and Foundation of the tier below the top.Foundation tier below serves as: Part of the construction of roughness to spread the load of the wheel to the ground base. Layers of peresapan, so that groundwater does not gather at the Foundation. Layer to prevent fine particles from the ground floor up to the top of the Foundation tier. Layers of protective layer of soil Foundation of the load wheels of heavy equipment (due to weak power base ground support) on the early implementation of the work. Layers of protective layer of soil Foundation of the influence of the weather mainly cloudy.

Base Layers Down (subbase Course)
under the foundation layer is the layer that lies above the pavement subgrade layer and under layers of foundation on. This layer serves as a foundation under: section of pavement construction to spread the wheel load to the subgrade. Lapis impregnation, in order ground water does not gather in the foundation. layer to prevent fine particles from the subgrade up to the top of the foundation layer. Layer the protective layer of the subgrade of the load wheels of heavy equipment (due to weak subgrade bearing capacity) at the beginning of the execution of the work. subgrade layer protective cover from the weather, especially the rain.
