AI Technical Summary
Technical Problem
Asphalt pavements contribute significantly to the urban heat island effect due to their black color and high infrared radiation absorption, and the decline in bamboo use leads to environmental issues like landslides and decreased biodiversity, while the construction industry emits large amounts of carbon dioxide.
Method used
Incorporating bamboo charcoal powder into asphalt mixtures at a specific ratio to reduce solar radiation-induced temperature rise and utilize bamboo as a carbon sink.
Benefits of technology
The asphalt mixture effectively suppresses road surface temperature and contributes to CO2 reduction by trapping carbon, addressing urban heat island effects and promoting bamboo utilization.

Abstract
The present invention provides an asphalt mixture that, when used as the surface layer of asphalt pavement, can result in asphalt pavement that suppresses temperature rise due to solar radiation. [Solution] An asphalt mixture containing an asphalt binder and an additive, wherein the additive contains bamboo charcoal powder, and the asphalt mixture contains 0.5 to 4.0 parts by mass of bamboo charcoal powder per 100 parts by mass of the asphalt mixture, and an asphalt pavement for suppressing road surface temperature rise containing the asphalt mixture as the surface layer.
