AI Technical Summary
The existing bridge deck pavement structure does not have the function of drainage and snow melting during use, which reduces driving safety during snowfall or snow accumulation and increases maintenance costs.
The system employs a combination structure of porous asphalt layer, heating wire, and protective sleeve. By combining the protective layer and the snow melting layer, it achieves rapid drainage and melts ice and snow through the heating wire, preventing heat loss. The melted ice and snow water is discharged through the porous asphalt layer.
It improves driving safety on the bridge deck under snowfall or snow accumulation conditions, extends the service life of the bridge structure, and reduces maintenance and energy costs.
