- Synopsis
- The objective of this study is to research the influence of heavy-duty vehicles fuel consumption for concrete pavement and asphalt pavement respectively, and then drag forces on the rolling vehicle tests are done by real truck coast down tests on the closed test course in Tsukuba, the taxiways in Narita Airport and the expressway in Obihiro. Measurement test method of drag forces on the rolling vehicle test (JIS D 1012) is unrealistic when it is applied for real roads. The JIS test method has some problems because the test distances are always short due to grade and curve on actual road conditions. This report suggests rolling resistance calculation method, which can evaluate road surface among drag forces by applying easier road grade adjustment than JIS test method. Further more, this study clears how the difference of rolling resistsance affects the fuel consumpution.
