Abstract
At present, the maintenance work is mainly based on the performance of the asphalt pavement, but the structure distresses inside the pavement is easily overlooked. Therefore, in view of the shortcomings of the evaluation system, this study carried out road nondestructive testing, and obtained performance, deflection basin parameters, and structure distresses of the asphalt pavement and using factor analysis to extract common factors of all indicators, which considers evaluation of performance is more comprehensive and determining the weights according to the contribution rate makes the evaluation results more unbiased. Can provide some guidance for the determination of pavement maintenance time.
