Toxic substance leaching test method based on cement stabilized macadam semi-rigid base

The invention discloses a toxic substance leaching test method based on a cement stabilized macadam semi-rigid base layer, which comprises the following steps: dehydrating each group of iron tailing powder mixture test pieces, crushing, and sieving; weighing a sieved sample with a specific weight, putting the sieved sample into an oscillation bottle, and adding distilled water; oscillating the oscillation bottle according to a specific frequency and a time length, and standing for a specific time length after oscillation; sucking the supernatant suspension, and filtering and injecting the sample into a sample bottle through a filtering hole with a specific specification; and sealing the sample bottle, and checking the leaching value of pollutants. The technical problems that in the prior art, when water-stable macadam is used as a road base, toxic substances in a preparation material are prone to being leached out by rainwater due to many pores of the water-stable macadam, and the concentration data of the to
