In the construction and maintenance of transportation facilities, geomaterials--soils and rocks--must be stabilized through chemical and mechanical processes. In applying these techniques, it is necessary to ensure the properties of stabilized geomaterials and their mixtures as applicable for use in the design of foundations, embankments, shoulders, subgrades, bases, and surface courses. In the new millennium, the challenge will be to develop better chemical stabilizers and mechanical stabilization techniques; new, quicker, and better testing methods; and better and environmentally safe methods for using waste materials for highway construction. This paper discusses some of the areas where research is needed to develop the materials and methods required to meet this challenge. |
