Basic Soil Test On Sub-grade Soil Material & Flexible Pavement Design On Road Linking â€“ Ugwuaji And Campus M, Imt; Enugu, Enugu State, Preface
This Case Study Is An Existing Pathway Or Fort Path Linking Ugwuji
And Campus 111 -imt- ...
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
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
- 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
This implies collecting soil samples that are disfigured their
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
1. To obtain a general information regarding the
nature of the soil and their variation with depth throughout the length of the
road under consideration.
2. To obtain information regarding the strength
characteristics of the soil.
3. To obtain information which will enable
engineers to group soils according to their appearances of the purposes of
complying different soils.
