(LI) of laterite under various percentage of cement (0, 7 and 13%) in 7-days
curing period. Ordinary Portland Cement (OPC) of 7 and 13% of soil weight is
added to the soil and various moisture contents are used based on the Optimum
Moisture Content (OMC) value from the compaction test (0.9, 1.0 and 1.1 from
OMC). The intention is to study the effect of the moisture content on the compaction
characteristic and compressive strength. The result from the compaction test
shows that the highest and optimum Maximum Dry Density (MDD) was recorded from
13% cement content. The Unconfined Compressive Strength (UCS) tests are carried
out and indicate that the strength increases as the cement content increases.
Based on the LI and UCS relationship, the strength has reached a minimum value
of subgrade design strength for low volume road (0.8 MPa) when the range of
the LI is -0.74 to -0.56 at 13% cement content.]]>Senol, A., T.B. Edil, M.S. Bin-Shafique, H.A. Acosta and C.H. Benson,200646365376Guyer, J.P.,20112011Kawasaki, T., A. Niina, S. Saitoh, Y.
