ゴムスクラップを乾留して回収したカーボンブラックのアスファルト舗装への利用

抄録

Dry distillation is an old fashioned technique developed a long time ago. We have developed a continuous dry distillation furnace which does not require any fuel for regular operation. The furnace can recover carbon black (RCB; recycled carbon black) from scrap rubber that can be used as a fuel for steel manufacture. We tried to discover another use for RCB in an asphalt pavement because of the good affinity between carbon black and asphalt. Our results show a tough and relatively low cost porous asphalt pavement which provides superior driving stability even in rain. The pavement prevents traffic noise in city areas. The asphalt has been paved by regional or national governments for more than 10 years without any problems. All roads with the asphalt remain good looking.
