Permeable asphalt freeze tests

WebPorous asphalt freezes as a porous medium rather than a solid block because permeable pavement systems are designed to be well-drained and infiltration capacity is preserved because of the open void spaces. Web10. máj 2024 · This paper aims to characterize the three-dimensional (3D) internal structure evolution of asphalt mixtures under freeze–thaw cycles. Asphalt mixtures with three levels of design void content (3%, 5%, and 7%) were prepared in the laboratory. Subsequently, X-ray computed tomography (CT) tests were conducted to capture two-dimensional (2D) …
