早在6年前,奥地利科学家受隔音室多孔板的启示,曾研制出一种多孔沥青混凝土,用来筑路,降低噪声。但这种多孔混凝土遇到寒冷的冬季,路面常被冰雪覆盖。为了快速清除多孔沥青混凝上路面的积雪或结冰,不得不经常撒盐,费用极高。因此,这个国家的公路往往因为路面孔洞全部结冰被迫关闭。不久前,英国科学家找 As early as six years ago, Austrian scientists were inspired by the soundproofing chamber’s porous plate and developed a porous asphalt concrete for use in road construction to reduce noise. However, this porous concrete encounters cold winters and the pavement is often covered with snow and ice. In order to quickly remove the snow or ice on the road surface of the porous asphalt, the salt must be frequently sprinkled and the cost is extremely high. As a result, roads in this country are often forced to close because of all ice on the road. Not long ago, British scientists found
