This study was carried out with aim of providing a valuable data base for emerging road construction
engineers involved in opening up the rural areas for extensive petroleum exploration activities. A total of 152
samples were randomly collected with different geotechnical parameters tested according to the British
Standards. The soils are generally fine to medium grained consisting mainly of clayey sand and sandy clays
with low to medium plasticity. The mean value of the optimum moisture content of less than 12% suggests that
during dry season, construction work in the field may not be a major problem. The soaked CBR values range
from 3 to 43%. This falls below the stipulated 180% by Federal Ministry of Works for base course material.
Consequently, this suggests that these soils should be subjected to some forms of stabilization to ensure the
durability of roads in this region.
