Asphalt mixture dynamic modulus test method

The invention discloses an asphalt mixture dynamic modulus test method, and belongs to the field of road engineering tests. The test method comprises the following steps: S1, manufacturing a small-size test piece, wherein the height of the test piece is 50-80 mm, the diameter of the test piece is 35-55 mm, and the height-diameter ratio of the test piece is 1.4-1.6; and S2, testing the road upper surface layer mixture test piece by a dynamic modulus compression test process, and testing the road middle lower surface layer mixture test piece by an indirect tensile modulus test process. Comparedwith the prior art, the test method has the advantages that the small-size test piece is adopted for testing, the dynamic modulus of the bituminous mixture of each structural layer of the bituminous pavement construction site can be accurately and effectively reflected, basic support is provided for more comprehensively evaluating the structural mechanical properties and structural design of the bituminous pavement, and g
