Study on Evaluation Index of Daily Maintenance Treatment Effect of Pavement Distress Based on Road Condition Rapid Detection Technology
Publication: International Conference on Road and Airfield Pavement Technology 2023
ABSTRACT
In recent years, China’s maintenance investment is increasing, but the contradiction between maintenance demand and maintenance investment is still very prominent. The daily maintenance cost is allocated according to the budget quota of highway maintenance project. Under the condition of limited maintenance fund, the treatment effect of daily maintenance is the key point during maintenance. In order to enable the highway managers to intuitively feel the treatment effect of daily maintenance of pavement distress, the concept of effective patch rate is proposed in this paper. Based on automatic detection data of asphalt pavement of the whole highway network in 2021 in a central province, the calculation method of the best effective patch rate is selected by comparing the two calculation methods of the effective patch rate, and then a more reasonable statistical method is selected by comparing the two statistical methods of the effective patch rate of the road section. Secondly, the correlation between the effective patch rate and the change trend of PCI in different levels of the number of damages is analyzed. Finally, the effective patch rate is verified by observing the improvement of PCI grade after simulated crack filling. The result shows that the effective patch rate can reflect the treatment effect in the daily maintenance of pavement distress.
