This case study is an existing pathway or fort path linking Ugwuji and Campus 111 (IMT) for a proposed road construction by the government of Enugu State.
This project encloses the following
- The condition of the existing sub-grade and its suitability for use as a good sub-grade soil material by processes of different lab test.
- Using the group index method and CBR method to design a flexible pavement on the pathway under consideration.
- The optimum moisture content (OMC) and the maximum Dry Density (MDD) which are obtained by various laboratory test with a view of applying corresponding values in the field.

COLLECTION OF SAMPLES AND LABORATORY TESTING PROGRAM
The test carried out in this project was on distributed soil sample.
This implies collecting soil samples that are disfigured their natural shape.
Soil samples were collected on three (3) trial pit along Ugwuaji and Campus 111 IMT Enugu. A total of three (3) samples were collected from the trial pits (one from each pit) using pick are and spade. The samples were taken at 1.0m depth in each pit. The samples were put in polythene bags and labelled A, B, C. The samples were spread on the floor of the soil laboratory and stones removed for seven (7) days to allow for air drying.
The laboratory testing program comprises mechanical analysis, compaction test and atterberg limit tests, and the California bearing ratio (CBR) test.
The objectives of the laboratory testing program were
- To obtain a general information regarding the nature of the soil and their variation with depth throughout the length of the road under consideration.
- To obtain information regarding the strength characteristics of the soil.
To obtain information which will enable engineers to group soils according to their appearances of the purposes of complying different soils.
