摘要

The results of a research effort executed at Central State University, Manufacturing Engineering Department on the development of theoretical models for low-volume airport pavement stabilization of clay-silt systems are documented. This study is considered very significant because it identifies a non-traditional method of soil stabilization for improving the subgrade strength of poorly graded clay-silt, considered one of the most difficult soil types to stabilize. The research (Phase I) focuses on: 1) Identification of a chemical additive capable of increasing the load bearing strength of clay-silt soil; 2) Additive application to a clay-silt soil system leading to increased bearing strength; 3) Development of mathematical models for soil strength prediction, and ; 4) In Phase II, field validation of the test results through studies of pavement rutting. Literature review suggests that little or no work has been done previously using organic additives in stabilization of clay-silt soil systems; however, many inorganic additives such as cement, lime, fly ash, and phosphoric acid have been satisfactorily tested on soils with good particle size distributions. Keywords: Statistical regression models. (kr)
