ENVIRONMENT LOAD OF PAVEMENT RECYCLING METHOD

In Japan, the Reclaimed Asphalt pavement have been widely used, and it works effectively as recycling materials. However, it does not make clear about the amount of environmental loads (CO2 emission, etc) through the lifecycle, such as material production, transportation, construction and rejection. Then, we evaluated environmental load through the lifecycle using general method of reclaimed asphalt pavement and in-place recycling method. The result is that the amount of CO2 emission of off-site recycling method is obviously fewer than its using new material, besides that in-place recycling method is even smaller than the others. However, it reveals that CO2 emission is increased, in case of the construction machine for in-place recycling is transported for long distance, In that case, it is necessary to consider selecting this method.
