We executed a wheel tracking test and Marshall stability test to evaluate the function of asphalt pavement mixed with kenaf fiber. Functions which we evaluated were fluidity resistance and optimal asphalt content. Global warming has been related to an increase of CO2. Discharge of CO2 by the road sector make up a quarter of that in civil industry. It is important for us to evaluate pavement from the viewpoint of the environment. So we evaluated reducing the amount of CO2 by asphalt with kenaf fiber.
As a result of each test in the laboratory, the asphalt mixture with kenaf fiver was superior in fluidity resistance compared with straight asphalt. The amount of CO2 emissions by asphalt mixture with kenaf fiber was about 93 percent of that of straight asphalt mixture.
