Study on the Decay Law of Asphalt Pavement of National Highway Considering the Cumulative Freight Traffic Volume
In order to predict the performance of asphalt pavement more accurately,the decay prediction model of as-phalt pavement indexes PCI and PQI is established based on the measured data of typical indexes PCI and PQI of asphalt pavement of Tianjin ordinary national highway,considering the impact of accumulated traffic volume data.And the prediction accuracy of the new model is analyzed and verified.The results show that the correlation coefficient and prediction progress of the prediction model after considering the impact of cumula-tive traffic volume are significantly provided,and the prediction accuracy is more than 92%.
