Bio-oils as asphalt bitumen rejuvenators
conference paper
Bitumen rejuvenators are used to improve or restore the physical and mechanical 12
performance of aged bitumen. Traditional bitumen rejuvenators have been a product of 13
crude‐oil. As crude‐oil production declines and the environmental and financial costs of 14
crude‐oil increase, there is an urgent need to identify more environmentally sustainable 15
bitumen rejuvenator alternatives. Bitumen rejuvenators generated from biological sources 16
offer an environmentally friendly and economically viable alternative to the crude‐oil 17
based bitumen rejuvenators. 18
This paper presents a study where microalgae‐oil was used as an aged bitumen reju‐ 19
venator. The chemical, physical and mechanical effect of microalgae‐oil on 70/100pen 20
aged bitumen were investigated. The results indicate that microalgae‐oil has a potential 21
to be used as an aged bitumen rejuvenator
