THE INVENTORIES OF CARBONDIOXIDES EMISSION FROM DIFFERENT PAVEMENT TYPE ON THE ROAD CONSTRUCTION

Transportation access was important element on regional development which have consequence on the environment degradation. This issues driving the land conversion, an exploitation of natural resources and pollution. This research was conducted to estimate the carbondioxides emission (CO2) on a road construction process. The data collects with bottom up approaches from 16 locations of road construction in Central Java which represents 2 pavement types (flexible and rigid). The GHG emission estimated with a conversion of fuel consumption (IPCC Method). The estimation result was analyze with a qualitative and quantitative method. An estimation generated the CO2 emission of flexible pavement was 261,91 ton CO2 similar with 21,84 kgCO2/m3 while a rigid pavement produces 149,22 ton CO2 similar with 7,44 kgCO2/m3 . The manufacture process became a stages with largest contributor on the CO2 emission. According to the result, a rigid pavement was an environmentally friendly method to reduces GHG emission on road construction with a distribution stages plays an important role as key categories.
