Choice of Crack Repairing Material for Asphalt Pavement Based on AHP

In the past decades, little attention was paid to the study on evaluation indexes of the performance of asphalt pavement crack repairing materials. In this paper, the indexes of material performance and economic evaluation based on the analysis of requirements for the crack repairing materials and the regulations are proposed. The indexes are subjected to interact, which will lead to inaccurate evaluation on the selection of crack repairing materials. Analytic hierarchy process (AHP) is employed to rank the indexes and select proper crack repairing material according to the evaluation result. The concrete steps of the AHP based model for the selection of asphalt pavement crack repairing materials is given. Finally, a practical example is employed to check the feasibility of this method.
