[0029] The present invention will be further described in detail below through the specific examples, the following examples are only descriptive, not restrictive, and cannot limit the protection scope of the present invention with this.
[0030] A method for determining the porosity of an asphalt concrete pavement core sample, which comprises the steps of separately measuring the bulk density of the asphalt concrete pavement core sample and the maximum theoretical density of the asphalt concrete pavement core sample, and then by the formula VV = ( 1 - ρ f ρ t ) × 100 % calculated.
[0031] Among them, the steps for determining the maximum theoretical density of asphalt concrete pavement core samples are as follows:
