日本道路建设公司研究出一种能有效地防止因路面冻结而导致车辆打滑的公路建设技术。该技术是在刚铺上沥青的路面上铺上一层使用硬质橡胶生产的新材料，这种新材料为直径Zcm的五角颗粒，将它铺在刚完工的沥青路面上后，再用压路机将其压人沥青路面中。压人路面后的五角形颗粒有
Japanese road construction companies have developed a kind of highway construction technology that can effectively prevent the vehicle from slipping due to the freezing of the road surface. The technology is in the just paved asphalt paved with a layer of hard materials used in the production of new materials, the new material for the pentagonal particles Zcm diameter, it will be laid in the just completed asphalt pavement, and then use roller Press it into the asphalt pavement. After the pressure of the pentagonal particles have pavement
