The soil from a borrow area having an average in-situ unit weight of 16kN/m3 and water content of 15%, was used for the construction of a road embankment (total finished volume 7000 m3). In half of the embankment due to improper rolling, the dry unit weight achieved was slightly lower. If the dry unit weights are in the two parts are 17 kN/m3 and 16.5 kN/m3, find the volume of borrow area soil used in each part and the amount of soil used.

The soil from a borrow area having an average in-situ unit weight of 16kN/m3 and
water content of 15%, was used for the construction of a road embankment (total
finished volume 7000 m3). In half of the embankment due to improper rolling, the
dry unit weight achieved was slightly lower. If the dry unit weights are in the
two parts are 17 kN/m3 and 16.5 kN/m3, find the volume of borrow area soil
used in each part and the amount of soil used.
