Performances of hydrated cement treated crushed rock base for Western Australian roads

摘要: Abstract: The resilient modulus (RM) of hydrated cement treated crushed rock base (HCTCRB) affected by amount hydration periods, compaction and dryback processes was presented using repeated load triaxial tests. related trends RM corresponding to the different periods still cannot be concluded. Instead, It is found that moisture content plays more major influence on performance. Higher additional water during HCTCRB, even at its optimum induced higher dry density, led inferior performance compared sample without addition. damper samples can improved through process superior addition same content. However, deliver comparable values density lower than other two types. These results indicate significant performances HCTCRB with regardless density. Finally, experimental parent material are evaluated K - θ model recommended Austroads. models provide excellent fit tested high degree determination.
