Permeable roadways, as a new type of ecological road, are increasingly drawing attention from both the public and the industry. Constructed with ecological permeable gravel, these roads allow rainwater to quickly seep into the ground, effectively replenishing groundwater and alleviating the urban heat island effect, thereby balancing the city's ecosystem. The permeable surfaces also allow for the passage of "ground energy," making the ground warm in winter and cool in summer, facilitating water percolation during the rainy season, and snow melting in winter, thereby enhancing the comfort of urban living. Moreover, due to their high porosity and large surface area, permeable surfaces have a strong吸附力 on dust, reducing dust pollution and noise levels. Basalt slag is particularly suitable for use as the permeable roadway gravel due to its quality.
