Lapisan pondasi atas (base course)L

Lapisan pondasi atas (base course)
Lapisan pondasi atas adalah lapisan perkerasan yang terletak di antara lapis pondasi bawah dan lapis permukaan.

Lapisan pondasi atas ini berfungsi sebagai :

Bagian perkerasan yang menahan gaya lintang dari beban roda dan menyebarkan beban ke lapisan di bawahnya.
Bantalan terhadap lapisan permukaan.

Bahan-bahan untuk lapis pondasi atas ini harus cukup kuat dan awet sehingga dapat menahan beban-beban roda.
Dalam penentuan bahan lapis pondasi ini perlu dipertimbangkan beberapa hal antara lain, kecukupan bahan setempat, harga, volume pekerjaan dan jarak angkut bahan ke lapangan.

The upper layers of the Foundation (base course)Foundation layer upon layer of roughness is located in between the layers of the Foundation of the bottom and the surface layer.A layer of Foundation over this function as: The part that holds the style of roughness of wheel load latitude and spread the load to the layers underneath. The pad against the surface layer.Materials for the Foundation layer over this should be pretty strong and durable, so it can withstand wheel loads.In the determination of this Foundation layer material to consider several things, among others, the adequacy of local ingredients, prices, transport distance and volume of work materials into the field.The Surface Layer (Surface Course)

The base layer (base course)
the base layer is the layer of pavement that lies between layers of sub-base and the surface layer, the base layer serves as: The pavement withstand the force of latitude of wheel load and spreading the load to the layer below. Bearing against the surface layer. The materials for the base course on this must be sufficiently strong and durable so it can withstand the load-bearing wheels. In determining the material base course is to consider several things, among others, the adequacy of local materials, pricing, volume of work and the distance transport of materials to field.
