An intelligent system and method for predicting service performance of pavement structures

Abstract

The invention provides an intelligent system for predicting the service performance of pavement structures, belonging to the technical field of road engineering, including a traffic axle load measuring device, a pavement structure mechanical response measuring device, a pavement structure temperature measuring device, a road rutting depth measuring device, a road surface Crack measurement device and pavement structure service performance prediction device. The present invention also provides a method for predicting the service performance of the pavement structure. According to the traffic axle load, internal temperature, layer bottom strain and crack conditions of the pavement structure, the fatigue damage crack development prediction model, the rut depth prediction model and the low temperature Cracking crack length calculation model, calculate the percentage of cracks developing from bottom to top to the surface area of ​​the pavement structure, the percentage of cracks developing from top to bottom to the length of the pavement structure, the predicted value of the rut depth and the length of low-temperature cracking cracks, and obtain the smoothness of the future pavement structure , accurately predicting the development trend of pavement structure service performance.

Description

technical field [0001] The invention relates to the technical field of road engineering, in particular to an intelligent system and method for predicting the service performance of pavement structures. Background technique [0002] The expressway network plays a vital role in social and economic development. my country has built the largest expressway network in the world. The construction of smart expressways featuring "smart cars" and "smart roads" is an important part of the transformation of the road transportation industry. The focus of development is the only way for my country to develop from a large transportation country to a transportation power. [0003] Pavement service performance is an important parameter for the construction of smart expressways. At this stage, the research on the service performance of expressway pavement is still in the real-time collection of highway pavement structure basic monitoring parameters such as vehicle speed, axle load and temperat...

[0003] Pavement service performance is an important parameter for the construction of smart expressways. At this stage, the research on the service performance of expressway pavement is still in the real-time collection of highway pavement structure basic monitoring parameters such as vehicle speed, axle load and temperature through the layout monitoring settings. It has not yet involved the use of high-speed Highway pavement monitoring parameters predict the service performance of expressway pavement structures, resulting in massive pavement monitoring parameter data being idle and not being used reasonably.
