Abstract


Generally speaking, lateralitic soils are found in tropical, warm climates. Different soils used in civil engineering construction failed when subjected to environmental conditions such as; Road deformation, erosion, settlement, and slope stability. The index properties of lateritic soil at Dorawar ‘Yan Nana, Wudil were determined. Also, the suitability of the lateritic soil of Dorawar ‘Yan Nana for pavement construction was determined. All the analyses were carried out by British standards. The sieve analyses were performed to determine the proportion of fine material present. The Atterberg limits test conducted includes the plastic limit, the liquid limit, and the plasticity index. The compaction of a soil mass results in an increase in dry density. CBR test was conducted to check the suitability of the soil. The moisture content average value was 18.37%, the liquid limit had an average value of 39.96%, the average value of the plastic limit was 27%, and the plasticity index was 11%. The specific gravity average value is 2.60, and the CBR average value of 14.62%. The CBR result indicated that Lateritic soil is not suitable for supporting heavy loads for supporting heavy loads in pavement construction.
