摘要

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.
