With the generation of a large amount of construction and demolition waste (CDW), many scholars have recently paid more attention to the recycling ofCDW. In this paper, we design a classification recycling method based on the degree ofCDWavailability in the recycling of CDW. Considering the important role of the government in reverse logistics, a model of reverse logistics network based on the trade-off between cost and recycling rate is put forward, which is subject to government subsidy. The model includes the location of classification processing center and ensures the best route of transportation. Then, the improved particle swarmoptimization algorithmis applied to solve the model to get Pareto frontier by transforming it into amultiobjective integer-programming problem. As a case study, the results of the statistical modeling used in this study indicate the feasibility of the model. Finally, according to the sensitivity analysis of government's subsidy, we evaluate the effectiveness of this program and its applicability.
