摘　　要：研究了由猪粪经热化学转化的生物沥青部分代替沥青混合而成的生物改性沥青(BMA)的性能。由猪粪转化的生物沥青不仅可以作为石油基胶结料的可再生替代品,还可以为猪粪废弃物的管理提供解决方案。此外,生物沥青的应用将降低沥青造价,降低沥青路面的施工成本。然而,生物沥青可能会降低胶结料的高温性能,为了解决这一问题,将多磷酸应用于BMA中,并探究其对BMA性能的影响。This paper investigates the performance of bio-modified asphalt(BMA)composed of bioasphalt partially replaced with asphalt blended from pig manure by thermochemical conversion.Bio-asphalt converted from pig manure can not only serve as a renewable alternative to petroleum-based binders,but also provide a solution for pig manure waste management.In addition,the application of bio-asphalt will reduce the cost of asphalt and reduce the construction cost of asphalt pavements.However,bioasphalt may reduce the high-temperature performance of the binder.To address this issue,this paper applies polyphosphoric acid to BMA and explores its effect on the performance of BMA.
