• Abstract:
  Due to the soft nature of subsurface soils in southern Louisiana, roads often have to ; be constructed on very weak subgrade soils with high in-situ moisture contents that ; do not have the suffi cient strength/stiff ness to support the construction/traffi c loads, ; which pose a signifi cant challenge for construction of highway projects. To solve such a ; challenge, cementitious additives such as cement, lime, fl y ash, cement kiln dust (CKD), ; and slag, alone or in combination can be used to treat/stabilize these soils to improve ; their engineering properties such as strength and stiff ness, thus providing the needed ; support for pavement construction. The long-term performance of treated/stabilized ; soils is usually infl uenced by the type and characteristics of the parent subgrade soil, the ; type and quantity of stabilization additive, the construction practices, the frequency and ; magnitude of loading, and the environmental conditions.
