摘　　要：结合江苏某高速公路维修工程,对TLA改性沥青路面进行了具体的研究,研究了TLA混合料配合比设计、灰分含量对沥青混合料试验结果的影响,并对实体工程进行了三年的跟踪观测,结果表明TLA改性沥青具有很好的高温稳定性及抗老化性能。Combined with expressway preservation project trial in Jiangsu province, performamce research on their TLA modified asphalt pavement has been carried out. Gradation design of asphalt mixture comprising TLA additives and ash component contained in TLA contribut to properties of asphalt mixes were studed. Tracing inspection on pavement project has been taken in the past three years, the results show that TLA modified asphalt has good high temperature stability and anti -aging performance.
