The invention relates to a construction quality detection and evaluation method for an asphalt pavement. The method comprises the following steps: determining reasonable detection sites of the asphalt pavement by ranked set sampling and density collection of sample points by a mathematical statistics method, and drilling cylindrical core samples, wherein the distance between the drilling positions of the core samples of the same group is 20 to 30cm; then developing a wheel tracking test, and evaluating the anti-rutting performance of the asphalt pavement according to the dynamic stability. The construction quality of the asphalt pavement can be effectively evaluated, and the one-sidedness caused by completely depending on random selection can be avoided, so that the whole construction quality of the asphalt pavement can be more comprehensively evaluated; damage on the pavement, which is caused by drilling of the cylindrical core samples, is lower than that of a plate type test piece, and the pavement is convenient to repair; furthermore, the adopted core samples can be also used for detecting the compactness of the pavement, so that damage of the pavement is further reduced; the accuracy of a detection result is guaranteed, and damage of the pavement, which is caused by drilling two core samples continuously at the same position, can be relieved.
