| description | The invention relates to the technical field of damming earth-rock material relative density testing, in particular to a method and a device for testing the relative density of an on-site original grading blasting rockfill material. The test method comprises the following steps: loosely filling a test material in the density barrel and calculating the minimum dry density of the test material when the height of the test material does not exceed the top surface of the density barrel; enabling the peripheral filler to be higher than the top surface of the density barrel, continuously filling the density barrel with the test material until the test material is higher than the top surface of the density barrel, and grinding the test material in the density barrel; the sleeve is installed on a top margin plate of the density barrel; measuring the internal volume of the space from the surface of the test material in the density barrel and the sleeve to the top surface of the sleeve, and calculating to obtain the tot |
