Problems solved by technology
However, for the method of pre-embedding sensors in the pavement construction process, due to the high temperature, heavy load and other uncertainties of the on-site construction, the survival rate of the pre-embedded sensors on the site is low, and the accuracy and accuracy of the pavement structure detection data cannot be guaranteed. reliability
However, for the detection method of coring or digging and filling sensors after the road construction is completed, due to the difference between the backfilled asphalt mixture and the original structure, it is easy to have the problem that the sensor cannot be integrated with the pavement structure, making the sensor's Errors in test results

The invention discloses a method for detecting the strain of a pavement structure. The method comprises fixing a test sensor to a mounting surface, and connecting the test sensor with an information acquisition device so as to acquire the strain data of the pavement, wherein the mounting surface is located in a section perpendicular to the ground. The detection method disclosed by the invention fixes the test sensor to a road section such that the test sensor is not liable to fault due to high temperature, heavy load, or other uncertain factors. The test sensor operates stably and ensures theaccurate detection of the pavement structure.
Description
technical field [0001] The invention relates to the technical field of road surface detection, and more specifically, to a method for detecting road surface structural strain. Background technique [0002] Under the action of vehicle load and external environment, the pavement will have different degrees of disease and damage. The common diseases and damage forms of pavement are cracks, potholes, subsidence, rutting and so on. The main reason is that the pavement structure and materials will be fatigued or fractured under the action of traffic loads and field environmental loads. Therefore, it is very important to detect the mechanical response of pavement structure to study the relationship between pavement structure performance degradation law and various influencing factors. [0003] In the prior art, the detection method of pavement structure strain is usually to embed sensors in the pavement layer during or after the construction of the pavement. However, for the met...
