9 Alternatif 4. - Pelat beton Fs  45 kg/cm2 = 31 cm.
- Lapisan aspal prime coat, 1,5 liter/m2 . - Lapisan CTSB yang relatif flexible = 15 cm. (UCS < 56 kg/cm2) - Harga relatif (initial cost) = Rp ,- /m2. (Catatan : Bila digunakan Lapisan CTSB yang lentur tetapi kuat dan tahan retak dengan campuran Ecocure atau Ecomix, tanpa lapisan prime coat, biaya relatip Rp ,-/m2)
