Roads are vital to societal development but require significant materials and energy, resulting in
environmental and economic concerns. In Pakistan, road infrastructure planning often prioritizes cost while
neglecting environmental impacts. This research integrates Life Cycle Assessment (LCA) and Life Cycle Cost
Analysis (LCCA) to evaluate the dual effects of traffic on road infrastructure, focusing on greenhouse gas
(GHG) emissions and pavement costs. Analysis of traffic volume and emissions monitoring highlights a
significant rise in GHG emissions with increasing traffic, emphasizing the environmental burden of existing
practices. LCCA results indicate that rigid pavements are more cost-effective over their life cycle compared to
flexible pavements, considering construction, maintenance, and rehabilitation costs. By addressing the gap in
Pakistan’s road infrastructure policies, this work advocates for strategies that balance ecological sustainability
with economic efficiency, offering insights into long-term, environmentally responsible development.
