| Summary: | Waste soil consists of waste material such as concrete debris, decayed wood, plastics and others. The
heterogeneous content of waste soil makes the geotechnical properties difficult to categorize and
analyzed. Laboratory works such as compaction test, consolidation test, triaxial and direct shear test
are conducted on waste soil to know its geotechnical properties. Based on standard proctor test, the
waste soil has a maximum dry density of 1567 kg/m3 with optimum moisture content of 29%. The
oedometer test shows the maximum displacement of 4 mm within 100 minutes. Based on direct shear
test, the undrained cohesion is in the range of 2- 4 kPa and angle of friction of 140-27o. The triaxial test
on unconsolidated undrained condition showed that the cohesion is 3 kPa and angle of friction on the
range of 00 to 10.50. These geotechnical properties are important to be used for foundation design for
future development at open dumping area in Malaysia. |
