    The study was conducted to study the complication arising from compaction curves of soils in Nassarawa – Eggon, North – Central Nigeria. Twenty representative samples were studied and the British Standard 1377 methods of sampling and analysis were employed for the grain size distribution and compaction. The soils are predominantly silty sand. Values of the optimum moisture content range from 10.0 g/cm3 – 34.5 g/cm3 while the maximum dry density values range from 1.61% to 1.88%. The compaction pattern can be noticed from samples AUS 14 to AUS 20 that the maximum dry density decreases because of the nature of the soil, being a boundary between the basement and sedimentary. The investigation has established two types of compaction curves: the single regular peaks and the irregular peaks, signifying the degree of compaction and nature of the soils.. There is a correlation between the soil index properties; water content and dry density on the kind of curves.
