The use phase plays a significant role in a pavement’s life-cycle environmental impact. For both cases shown here it accounts for over 25% of the total global warming potential. However, its contribution depends upon the specific context: for lower traffic volume applications it has lower impacts, and for higher volumes it has higher impact. MORE
