Experimental Analysis of Water-holding Behavior of Permeable Asphalt Mixture
https://orcid.org/http://orcid.org/0000-0003-1323-890X
Permeable asphalt mixtures are widely used to achieve good permeability of the pavements used for urban road surfaces. Based on the law of water migration in permeable road structures, the water-holding performance of permeable asphalt mixtures was analyzed and the evaluation indexes were determined. Open-graded asphalt friction course (OGFC-13) permeable asphalt mixture was selected, and the changes in the saturation, water retention, and water-holding rate of OGFC-13 permeable asphalt mixtures with different porosities were compared using water-holding equipment. The water-holding characteristics of permeable pavement materials under different seepage conditions were analyzed. A model of the relationship governing the water-holding capacity of the permeable asphalt mixture, water action conditions, and material porosity was established by a linear fitting method, and the reliability of the model was verified by comparison with laboratory test results, providing a foundation for related research on the water-holding and cooling behavior of permeable pavements.
