Multicone KILN Dust as a Soil Modifier in Highway Subgrade Construction
Design and construction of highway pavements of fine-grained soils, such as clays and silty clays, or soils with poor or marginal engineering properties, are frequently
encountered by pavement design engineers.  Bearing strengths of fine-grained soils are very...

Residue By-Product From an Atmospheric Fluidized Bed Combustion Process Used in Highway Subgrade Modification
A spent lime residue from an atmospheric fluidized bed combustion process was used to modify two highway soil subgrade sections on a route in Kentucky.  The AFBC
residue contains high percentages of CaO, Ca(OH)2, and MgO and produces soil-lime pozzolanic reactions when mixed...
