Abstract

Abstract

Permeable pavement is one of the key technologies for stormwater runoff emission reduction, of which the frost heaving damage in cold area is an urgent problem. Permeable bricks are widely used pervious pavement materials. The frost resistance of permeable pavement surface in different porosity, water saturation and permeable base thickness was studied through the freeze-thaw cycle experiments. The results showed that the porosity of the surface layer had a negative correlation with its frost resistance, and the higher porosity, the worse frost resistance of the surface layer. There was a negative correlation between the surface water saturation and its frost resistance, also. The frost resistance descended as the water saturation increased. The critical value of the surface water saturation for frost heave damage was 90%. When the water saturation of the surface layer was lower than 90%, the frost resistance was less damaged; when the water saturation of the surface layer was higher than 90%, the frost resistance got obviously worse. The thickness of permeable base had little effect on the frost resistance of permeable pavement. The three main influencing factors on the frost resistance of permeable pavement surface were in the extent sequence of water saturation > porosity > thickness of permeable base.
- permeable brick pavement,
- frost resistance,
- water saturation,
- porosity,
- freeze-thaw cycle,
- urban stormwater management
