Abstract
The CBR test is a simple and well recognized method of assessing the strength of subgrade. There are also many other Geotechnical tests which can be used to ascertain the quality of the subgrade soil, the quality of the soil that is used for subgrade may differ and this may depend on the amount of water that seeps through the soil. In this study, the degree of soaking was varied in days starting from un-soaked (0 day) to soaked (day 1) up to (day 5) to enable the measurement of the saturation level in different types of soil in Awgu LGA. Furthermore, the Engineering features of the soils which included the CBR at different saturation levels were also studied. According to the results obtained, as the soaking period increases from day 1 to 5 for all the samples, there was remarkable decrease in the CBR of soil samples from 100% to 5% in all the samples.
