Problems solved by technology

[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. Conservation provides scientific basis

Embodiment Construction

[0128] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0129] In this embodiment, the expressway in Jinan, Shandong Province is taken as an example, and the experimental road section is selected on the expressway. The experimental road section is an asphalt pavement, and the pavement structure is as follows: figure 1 As shown, adopt a kind of method that the present invention proposes to be used for predicting the service performance of pavement structure to predict the smoothness of highway pavement structure of experimental road section, specifically comprise the following steps:

[0130] Step 1, obtain the pavement structure parameters of the experimental road section, the pavement structure parameters include the thickness of the asphalt layer , target reliability , temperature adjustment coefficient , Adjustment coefficient for seasonally frozen soil regions And the thickness...

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...
