Paper by YOSHIMOTO KAZATO HAYAKAWA from ISCR 11th 2010 Seville Spain
The purpose of this study is to research the influence of fuel consumption of heavy-duty vehicle for concrete pavement and asphalt pavement respectively. It was decided to adopt a new approach for vehicle fuel consumption -- measurement of the running resistance of vehicles to investigate their rolling resistances due to different pavement types. In this study, the running resistance is basically measured by coastdown tests in accordance with JIS (Japanese Industrial Standards) D 1012 (hereafter referred to as the JIS method). However, the JIS method has some problems because the test distances are always short due to grade on actual road conditions. It was therefore decided to investigate grade correction through a new approach. As a result, the rolling resistance of asphalt pavement at the test sites is higher than concrete pavement by 5.9% to 19.4% and the fuel consumption rate of asphalt pavement is higher than concrete pavement by 0.8% to 3.4% with Mode JE05, which is an inner-city test cycle mode with a relatively low speed, and by 1.4% to 4.8% with an inter-city test cycle mode at a constant speed of 80 km/h through longitudinal grades simulating expressway by comparison within each site.
