5. EMBANKMENTS AND BACKFILLINGS (Code list AA05)

5.1 Embankment (m3

) (Code AA05A)

This work is to be evaluated on the basis of its volume after compaction.

The volume is obtained by the average of the surface area of the sections (a1a2a3etc.)multiplied by the distances, taken along the axis, between the considered sections(a1a2a3etc.)See ANNEX 8.

The surface area of the section is to be calculated by multiplying the average of the widths, as perconstruction drawings by the height.

The height is the average of the values measured on the axis, between the top elevation of theembankment and the bottom elevation of excavation, according to the drawing issued for

construction.

Any part exceeding the dimensions required in the construction drawing is too not to be accountedfor.

See the following explanatory example:

a1+a2 a2+a3 a3+etc.VEM = ---------- x L1 + --------- x L2 + ---------- x L3 etc.

2 2 2

w1+w2 w1.2+w2.2.a1 = ---------- x h1 a2 = -------------- x h2 etc.

5.2 BACKFILLING (m3) (Code AA05B..)

This work is to be evaluated on the basis of its volume after compaction.

The volume of the backfilling is to be calculated on the basis of the dimensions (width, height andlength) show in the drawings issued for construction regardless of the actual volume of thebackfilling executed.

See ANNEX 2 and 9

Following the calculation formula indicated in Annex 2 and 9, the Volume of Backfilling ( VB ) is thefollowing:

a) VB = (VGE + VE1 + VE2) (volume of subbase crushed stone and concreteincorporated in the backfilling)

b) VB = VE3 (volume of the concrete incorporated in the backfilling)

c) VB (of subbase crushed stone) = a2 x b2 x hs
