Abstract

The invention discloses a pavement performance prediction method and system, comprising: respectively fitting the maximum value, minimum value, mean value and standard deviation of the annual historical pavement performance indexes to obtain the first regression equation of the maximum value and the first regression equation of the minimum value The second regression equation, the third regression equation of the mean value and the fourth regression equation of the standard deviation; according to the regression equation, the maximum value, minimum value, mean value and standard deviation of the pavement performance index of the year to be predicted are calculated respectively; according to the year to be predicted The standard deviation and the mean value are used to obtain the probability density function of the pavement performance index in the year to be predicted; the distribution interval limited by the maximum and minimum values ​​of the year to be predicted is obtained; according to the probability density function of the year to be predicted, each The distribution probability of the pavement performance index corresponding to the unit distribution interval; the value of the pavement performance index corresponding to the unit distribution interval with the largest distribution probability is used as the predicted value of the pavement performance index in the year to be predicted. The prediction result of the present invention is more accurate.

Description

technical field [0001] The invention relates to the technical field of pavement performance prediction, in particular to a pavement performance prediction method and system. Background technique [0002] Pavement performance directly affects pavement maintenance strategies and maintenance capital investment. In order to optimize the allocation of a given maintenance budget in time and space and determine the best pavement maintenance plan, it is necessary to predict the pavement performance within a certain period of time. [0003] Over the years, through the development of national road network technical status inspection and evaluation work, a large number of evaluation historical data resources have been accumulated and stored, but there is a lack of collation statistics and effective use of these data resources, so the prediction of pavement performance is relatively inaccurate. Contents of the invention [0004] Embodiments of the present invention provide a method an...
