Highway Asphalt Pavement Maintenance Machinery To Optimize The Configuration And Evaluation System

With developing of expressway construction and coming into the maintenance period of accomplished expressway, early damages largely come into being in accomplished expressway. It's an important topic on the expressway maintenance in China.By analyzing damage condition of expressway asphalt pavement, the paper sums maintenance technology, technology process of construction and machinery equipment fitted in with process. Using the theory of multiple objective optimization, the paper sets up the model of optimal allocation for maintenance machinery; and presents the practicable methods and procedures for the model. Utilizing a similarity degree-based method for triangular fuzzy number based multi-attribute decision making with preference information on alternatives, the paper establishes evaluating model of expressway maintenance machinery configuration. The paper uses an actual example to demonstrate the appropriation of the evaluating model.By the researches mentioned, the paper gives some opinions on optimal allocation for maintenance machinery of expressway asphalt pavement.
