This study presents the research effort to evaluate problematic A-2-4 soils in highway construction. An experimental program was conducted to evaluate six problem soils. The soils were chosen by the Florida department of Transportation (FDOT) because of past problems experienced during construction. A set of laboratory tests was performed to determine the engineering properties of each soil. A review of the current understanding of expansive soils in highway design was also conducted. The results of the experimental program showed that certain engineering properties give a possible indicator of potential construction problems and can be used to screem A-2-4 soils before use in highway projects. The results also showed that the presence of expansive clay is not a conclusive indicator of a problem A-2-4 soil.
