Abstract
Materials such as those used for granular embankment or base course in highway construction can be obtained by blending natural earth deposits. The mathematical theory of linear programming is used to determine the quantities of each available natural earth deposit to be blended so as to produce the desired material at least cost to the constructor. An actual situation involving granular materials is formulated and solved. The results are examined for reliability and are interpreted with and without the aid of the principles of engineering economy. Linear programs are described for practical cases which are ramifications of this actual situation. Limitations of the applicability of linear programming to practical cases in general are noted.
