The invention relates to a pavement structure performance evaluation method based on a laser type high-speed deflectometer. The method comprises the following steps: collecting deflection test data of a detection area based on the laser type high-speed deflectometer and obtaining equipment parameters; taking the impact stiffness modulus ISM as a pavement structure performance evaluation index, and determining an initial evaluation index grading parameter; correcting the initial grading parameters based on the construction history of the test area, the pavement structure composition and the test environment to obtain evaluation index grading parameters; processing the acquired deflection test data to obtain fitting data and images of the impact stiffness modulus ISM of each test line or test surface; and obtaining a pavement structure performance evaluation rating of the detection area based on the fitting data, the image and the evaluation index grading parameter. Compared with the prior art, the pavement structure performance evaluation method based on the laser high-speed deflectometer provided by the invention has the advantages that the detection evaluation work is effectively guided, and a theoretical basis is provided for scientific maintenance and management of the pavement.
