SUITABILITY OF AVAILABLE LATERITE MATERIAL IN ILORIN EAST LOCAL GOVERNMENT AREA FOR ROAD CONSTRUCTION

ABSTRACT

Soil failure is a common sight in Nigeria road and structural constructions. The main purpose of this project is to investigate the suitability of the available laterite materials in Ilorin east local Government.

To determine the suitability of the soil in the three selected areas, Various tests were carried out on- the samples and those are classification test which is a test used in determining the type of soil. Also strength evaluation test was also done on the soil samples so as to determine the bearing capacity, density and strength of the soil and such strength evaluation tests, CBR test and moisture content test.

The project was undertaken following various laboratory soil test result to ascertain the type, strength and suitability of soil for any civil Engineering work.

After all these have been performed results are observation were made and final conclusion and recommendation were taken.
