Evaluation of Engineering Properties of Problematic Soils in Highway Construction

摘要

This paper presents a research effort to evaluate problematic A-2-4 soils in highway construction. Typical problems encountered by contractors in Florida during construction are that the soils retain excess moisture or are difficult to dry and compact. One prevalent theory was that the construction problems were directly related to the presence of expansive clays in the soils. An experimental program was conducted to evaluate six selected problem soils. Laboratory tests were performed to determine the engineering properties of each soil. The results of the experimental program showed that certain engineering properties of each soil. The results of the experimental program showed that certain engineering properties give a possible indicator of potential construction problems and can be used to screen troublesome A-2-4 soils before use in highway projects.
