Void Bulk Modulus Reduction of Porous Asphalt Mixture Based on Porous Linear Elastic Continuum Theory
The void bulk modulus reduction of porous asphalt mixtures was evaluated using the Gassmann's equation to describe the relationship between the various bulk moduli and the percentage of air voids in porous asphalt mixtures along with the theory of linear elastic material with voids. A continuum interpretation of the porosity of the material was presented and used in the paper. The void bulk modulus was considered to represent the air voids reduction of the porous asphalt mixtures. The data showed a larger reduction in the void bulk modulus for the dry state when compared to the saturation state. The void bulk modulus under the dry state decreased by 8.4% with the 25% reduction in the initial air voids. However, the void bulk modulus decreased by 7.8% under the saturation state.
