The utility model belongs to the technical field of road capability test, particularly, involve a rut shape analogue means that is used for laser rut appearance to mark. Rut shape analogue means includes two ruts demarcation pieces and a datum plane board, the piece parallel placement is markd on the datum plane board to two ruts to keep closely connected with the datum plane board, the rigidity echelonment wedge that the piece was length 1000mm, width 100mm, high 100mm is markd to the rut, and 10 grades are established to the ladder, the width 100mm that the ladder was marked time, high 10mm. Compared with the prior art, a rut shape analogue means that is used for laser rut appearance to mark simple operation, the testing result degree of accuracy is high, and can in the same termly carry out the demarcation under the multiple rut degree of depth condition, has greatly improved efficiency and precision that laser rut appearance was markd, has fine popularization and application and worth.
