Machine Learning‐Based Analysis and Prediction of the Influence of Meso‐Void Characteristics on Sound Absorption Coefficient of Porous Asphalt Concrete
Porous asphalt concrete (PAC) is widely recognized as an effective noise‐reducing pavement material due to its interconnected void structure. However, the quantitative relationship between meso‐scale void characteristics and the sound absorption coefficient is not well understood, which limits the precision of mixt...
