【Abstract】 In this paper,neural network model of pavement condition index(PCI) evaluation was established based on the theory of BP network.IRI and DR was used(damage rate)as training data,and the model shows very accurate results.Furthermore,compaing the accuracy of neural network model and regression model was brought out after being compared.The result shows neural network model has been widely used in evaluation of pavement performance.更多还原
