Problems solved by technology

[0006] The technical problem to be solved by the present invention is: in order to increase the average service life of the road network, control the deterioration speed of the road surface performance in the road network, rationally allocate limited maintenance and repair funds, and reduce the huge amount of money required for major and medium repairs and reconstruction of the road surface. The invention provides a method for evaluating the technical health status of the road network and pavement to ensure that the road network is maintained in a good service state

Abstract

The present invention provides a highway network pavement technology health condition assessment method. The method comprises the steps: surveying the operation age limits of all the roads with the same grade and the same pavement structure in an area and the pavement technology state parameters of each kilometer; establishing a mathematical relationship model of the pavement operation age limits and the technology state parameters, obtaining the regression equation and curve of the pavement technology state parameters, and calculating the technology state decaying values year by year and the regression pavement technology state average decaying lane mileage; performing statistics of the technology state decaying lane mileage of each kilometer and performing accumulation of the technology state decaying lane mileage of each kilometer, and obtaining the current pavement technology state decaying lane mileage; and assessing the highway network technology state health degree through comparison of the sizes of the average value and a measured value so as to provide basis for the area highway maintenance planning and decision. The highway network pavement technology health condition assessment method can predict the future usage condition of the pavement, and the predication data can be used for providing reference for the mid-long term maintenance and the planning of the pavement.

Description

technical field [0001] The invention relates to a method for evaluating the technical health status of a road network pavement, belonging to the field of road maintenance planning technology and management, and in particular to a method for evaluating the technical health status of a road surface. Background technique [0002] With the rapid development of economy and society, the traffic volume of national and provincial trunk roads is increasing rapidly, and the pressure on road maintenance and management is getting heavier. Increased pavement service level requirements and increasing expectations for reducing traffic congestion induced by road maintenance projects. Highway management and maintenance agencies are not allowed to allocate a large amount of funds for regional road network maintenance to ensure that the road surface is at a good level. [0003] Due to the influence of factors such as different years of road construction in the road network, different traffic ...
