This research analyzes the characteristics of clay soil in the campus environment of State University of< p>
Manado through laboratory testing Two soil samples were evaluated with variations of moisture content < p>
3 below and 3 above the Optimum Moisture Content OMC for laboratory CBR testing Based on the< p>
standard proctor test results the OMC values were approximately 23 25 for the first soil sample and 23 < p>
for the second soil sample with a dry unit weight of around 1 44 g cm for the first soil sample and 1 45< p>
g cm for the second soil sample In the soaked CBR test the soaked CBR values at the OMC variations< p>
were 5 81 for the first sample and 4 15 for the second sample A 3 increase in moisture content above< p>
the OMC showed a decrease in CBR value by 5 72 while a 3 decrease below the OMC resulted in a< p>
5 97 increase in CBR value This study provides a deep understanding of clay soil response to changes< p>
in moisture content relevant for infrastructure planning and construction < p>
