Abstract Bio-oil recycled asphalt binders in road engineering can help solve the problem of oil shortage and reduce the environmental pollution and sustainability. This paper investigated the road performance of the aged asphalt binder by adding bio-oil so that the aged asphalt binder could be reused to reach purpose of reuse. The residual soybean oil was selected as rejuvenator and blended with aged asphalt binder at 0%, 2%, 4%, and 6%, respectively. The results showed that bio-oil increased the penetration of aged asphalt binder, the penetration of bio-oil recycled asphalt binder with a bio-oil content of… More >
