LCCO₂ OF CONCRETE PAVEMENT AND ASPHALT PAVEMENT CONSIDERING FUEL COSUMPTION OF HEAVY-DUTY VEHICLES

Abstract

 It was reported that the fuel efficiency of heavy-duty vehicles was reduced by driving on concrete pavement compared of asphalt pavement because the rolling resistance of concrete pavement is smaller than asphalt pavement, and the reduction of CO₂ emission by improvement of the fuel efficiency was expected. CO₂ emission of concrete pavement considering the effect of the fuel efficiency reduction on N7 traffic was calculated and compared with asphalt pavement. As a result, the amount of CO₂ emission of concrete pavement only construction was bigger than that of asphalt pavement since the effect of cement was big. However, the amount of CO₂ emission of concrete pavement was smaller than asphalt pavement by considering fuel efficiency reduction of heavy-duty vehicles as contribution to environment, which contributed to decrease CO₂ emission significantly. Besides, in the case of heavy traffic of heavy-duty vehicles comparatively on N7 traffic, amount of CO₂ emission of concrete pavement is smaller than that of asphalt pavement.
