In this paper, the life cycle assessment (LCA) of utilizing a functionalized polyolefin (FPO) as an additive in polymer modified bitumen (PmB) has been studied from a ‘cradle-to-use’ perspective utilizing SimaPro®. The assessment was made as per pavement construction in North India and included other additive solutions such as Styrene-Butadiene-Styrene (SBS). The LCA results indicate lower CO2 emissions with the functionalized polyolefin, especially derived from energy consumption differences during PMB manufacturing. Pavements were prepared as per PG 76-10 E requirements with different grades and network survey vehicle (NSV) data was gathered post multiple seasons of the pavement usage. The NSV data on pavements made with FPO additive indicated that fatigue, rutting resistance, and macro-texture roughness behavior met the demanding requirements as per standards.

摘要

In this paper, the life cycle assessment (LCA) of utilizing a functionalized polyolefin (FPO) as an additive in polymer modified bitumen (PmB) has been studied from a ‘cradle-to-use’ perspective utilizing SimaPro®. The assessment was made as per pavement construction in North India and included other additive solutions such as Styrene-Butadiene-Styrene (SBS). The LCA results indicate lower CO2 emissions with the functionalized polyolefin, especially derived from energy consumption differences during PMB manufacturing. Pavements were prepared as per PG 76-10 E requirements with different grades and network survey vehicle (NSV) data was gathered post multiple seasons of the pavement usage. The NSV data on pavements made with FPO additive indicated that fatigue, rutting resistance, and macro-texture roughness behavior met the demanding requirements as per standards.
