According to the real requirement of mix design in highway engineering,as well as considering the optimal economic problem,we build a mathematical model.The main solution steps using the tool of "Pro-gramming Solution"which is supported by Excel are introduced.Finally the estimation in technical and eco-nomic aspect about the result of the proposed model is analyzed.The main advantage is that we build a linear programming mathematical model which object function aims to obtain lower cost of mixture.The result is precise and can be obtained easily by using Excel,so the operator can have not the ability of programming.
