Steps to oversee the implementation of road projects - an earthworks 3

The work of the foundation layer under the Sub base:
1 - Check the conformity of material specifications to conduct the following tests on the samples provided:
- Gradient (analysis Almnkhala).
- Limits Atrberg (liquidity limit - limit plasticity - plasticity coefficient).
- Resistance to corrosion (land) to your Los Angeles.
- Sand equivalent.
- California Bearing Ratio.
- Examination of Authenticity (Almagnisom sulfate / sodium).
- Proctor test on materials to determine the maximum dry density and optimum moisture content.
2 - give permission to the contractor providing the materials of the layer under the foundation approved.
3 - check the matching layer materials are supplied under the base of the samples previously approved.
4 - Verification of the brush layer and sprayed with water and tillage, mixing and stirring.
5 - Receive Messahaa class (line axis + attributed).
6 - Verification of the flat surface of the layer in the longitudinal and transverse directions.
7 - check the rate of compaction and moisture content of field-density test.
