Refilling shall be done with laterite or scoria according to the required
profile, on a minimum thickness of 10 cm measured after compaction. The cross
section should correspond to that specified for the road section.

The required compaction of the surfacing shall be 95% of the dry modified
optimum Proctor density. To obtain this result, the Contractor shall use laterite or
volcanic scoria bulked, reserved and approved according to the requirements of
these technical specifications and at least four passes of compaction equipment
p. 33
 previously approved by the Project Manager on the entire surface of the
surfacing course and water this surface whenever necessary during compaction.
Geotechnical test at an interval of every 200m shall be conducted to determine
this density

Where the Project Manager is dissatisfied with the job done or doubts the
compaction results, he shall at his own expense conduct control tests and where
necessary ask an approved laboratory to do so. If on a section, more than 20%
of compaction tests are below standards, the contractor will repeat compaction
and new tests will be conducted before acceptance of the section. Expenses for
such laboratory tests shall be borne by the contractor. The Project Manager shall
check the thickness of the layer.

No thickness below 10cm shall be tolerated. If measuring reveals less

than 10cm, the corresponding section shall be further scarified, refilled and
compacted until the required thickness and degree of compaction is obtained.

In such a case, laboratory expenses shall be borne by the contractor. Just as defined in
Article 9 above, a patch shall be carried out before the works.

1.3.21 METALLIC CULVERTS

13.1 Base and mounting

In sites with low bearing capacity soil and to prevent subsequent

settlement of the structure, culverts shall be placed after the removal of this soil,
if any, from the base as instructed by the Project Manager.

Notwithstanding this provision, the contractor shall take responsibility for

any damage which may result from deformations of the culverts due to
settlement or other causes.

The contractor shall choose the periods of zero discharge or of

13.3 Upstream and downstream improvements

The laying of culverts shall be completed by carrying out improvement works

upstream and downstream, clearly defined in the execution drawings and adapted to
the landscape and different local conditions specific to each structure.

1.3.23 Compensation for the damages caused to third parties

It can happen that the company hurts an individual in a deliberate or accidental manner
(destruction of crops, habitat, etc). If this wrong is not taken into account by the project
owner or contracting authority, it will have to be compensated with the expenses from the
company and satisfactorily to the party. On the other hand, he will have to issue a
certificate of compensation to him, in order to avoid any other later complaints.
