Bitumen Modification: New Technology

Herman Marais

Herman Marais introduces emerging technologies in bitumen modification including polymer modification (PMB), crumb rubber, micro filler and nanotechnologies. He concludes that PMB is the most popular modifier with exciting future prospects, crumb rubber use is expected to increase as storage stability risks are reduced and new blends are developed, micro filler shows promise, and nanotechnologies will become less expensive with increased production.
