Abstract |
This study was intended to estimate of relative compaction on the ground under the load using of portable FWD. The outcome in the wake of the study is highlighted as below. Viewing the variation of dynamic deflection modulus depending on a number of compaction, when a number of compaction increased to 8 (18.3MPa) from 4 (ISMpa). a dynamic deflection modulus increased 27%. and when a number reached to 12 (27.gMPa). it doubled the value indicated in 4. Viewing the relationship between dry density and dynamic deflection modulus in line with the increase in a number of compaction. a number of compaction by the roller reaching to the degree of compaction equivalent to 95% of max dry density was 13. with a dynamic deflection modulus indicating 27MPa ~ 29MPa.
