Abstract
Analysis on the properties of soil/rocks that lead into the cause of
road failure has been carried out along 78km in Tashan –kaji highway area of
Toro L.G.A, Bauchi, and Northeastern Nigeria. Geotechnical, geochemical,
mineralogical and geophysical analyses were conducted to evaluate the cause of
the failure in the study area. The results of the laboratory tests showed that
the percentage amount of fines ranges from 14.2 to 71.3%, natural moisture
content from 8.8-15.2%, liquids limit is in the range of 16.5-37.5%,linear
shrinkage between 0.7-5.0%,plastic limit range from16.5-18.0%,plasticity index
ranges from 18.5-22.5%,maximum dry density ranges from 1.84-1.97g/cm3,specific
gravity ranges from 2.23-2.43%,coefficient of uniformity (Cu) is 0.93-3.8% and
the coefficient of curvature (Cc) is between the range of 4.5-6.5%. The cone
penetrometer Test (CPT) shows a resistance value of 21-143kgf/cm2.The
major mineral that is predominant in the studied area is kaolinate. The major
oxides that are present are CaO,SiO2,Na2O,Al2O3,Fe2O3,K2O
and MgO. The result of the Electrical Resistivity revealed a low resistivity
values at the profile 5 and 7 ranging from 120Ωm-200Ωm, between a distance of
15m-170m along the profile to a depth of 6.8 and a low resistivity value
ranging from 60Ωm-121Ωm, between a distance of 70m-110m along the profile to a
depth of 13m.It was concluded that geotechnical investigations of the soil
samples around the study area have shown that the grain size distribution
characteristics of the soils range from poor-fair hence will not be used for
foundation and fills materials.
