摘　　要：乳化沥青性能的优劣是影响稀浆封层路用性能的关键因素之一,而乳化沥青的储存稳定性对稀浆封层的长期储存和远距离运输等都有重要的影响。因此,本研究基于自制复合改性乳化浅色沥青,并通过三大指标等高低温性能和储存稳定性能对不同掺量改性剂的复合改性乳化浅色沥青的性能进行评价。结果表明:当改性剂为3.5%时,乳化沥青稳定性相对较好,满足稀浆封层乳化浅色沥青的规范指标。The performance of emulsified asphalt is one of the key factors affecting the road performance of the thin slurry seal,and the storage stability of emulsified asphalt has an important influence on the long-term storage and long-distance transportation of the thin slurry seal.Therefore,this study is based on the homemade composite modified emulsified light-colored asphalt,and the performance of the composite modified emulsified light-colored asphalt with different amounts of modifiers was evaluated by three major indicators,such as high and low temperature performance and storage stability.The results show that:when the modifier is 3.5%emulsified asphalt stability is relatively good,to meet the specification of thin slurry seal emulsified light-colored asphalt indicators.
