O-23 半炭化処理による高性能木質舗装材の製造・利用実証

抄録

Wood pavement has advantage for lighter weight, better walkability and lower heat storage, but has disadvantages for short life-time due to biological degradation, compared to the conventional asphalt-concrete pavement. In this study torrefaction was employed to upgrade wood for pavement production, and then the optimum torrefaction condition was found to show enough characteristics in the laboratory scale. Demonstration of the pavement has been done at several areas in Japan and their characteristics are being investigated
