Abstract
This paper documents a research effort conducted regarding chemical stabilization of the naturally wet and problematic clayey soils typically found as subgrade in south Louisiana, and provides detailed information on experiment design, instrumentation, and conducted field and laboratory tests. The objectives of the study include the exploration and development of a methodology to build reliable and conservatively achievable subgrade layers, stabilized with cementitious agents at various field moisture contents so that a treated subgrade layer would not only provide a working table for pavement construction, but can also function as a pavement subbase layer that contributes to the overall pavement structural capacity. The laboratory and field results confirmed that among subbase treatments evaluated, cement-treated soil provided the best-performance followed by lime-treated soil.
