AB  - This  study  evaluates   the  use  of  plate  load  test   in ascertaining elastic modulus, Es  of a site  in  Calabar, Niger Delta, Nigeria. The area depicts a coastal plain environment with typical    sandy and clayey formation. Four plate load test was carried out within  the area of  investigation , with  load    settlement  curve   which indicates  a  firm to  stiff partial  cohesive  soil. The   result shows geotechnical properties of the soil which depicts values above the A line plot on the plasticity chart. The  average  liquid  limit   and   the plastic  limits  values  of  30.65%  and  15.9%    respectively    shows   that    the  soil under  consideration is low  in  compressibility. The average moisture content   of   soil is low.  An average  elastic  modulus  value  of  4302.289 KN/m2  was  obtained  in  the  elastic  range (initial  tangent  modulus), which  is  indicative  of  a  firm  clay .  This  value   conform reasonably   with  those  obtained   by   method proposed  using  Cone Penetrometer Test (CPT) with an  average   cone  value of  17Kg/cm2 with  Es= 4165 KN/m2.  Generally,  geotechnical   parameters  of  the  soil   reflects   the  nature   of   the  load  settlement  curve  obtained  from  the  test  points. Immediate settlement analysis with Es carried out showed low magnitude of compressibility in the study area.
