一种温拌再生沥青及其制备方法
摘要：
本发明公开了一种温拌再生沥青，由以下重量份的原料制成：老化沥青100份，复合再生剂8～30份，复合温拌剂5～15份；所述复合再生剂由以下质量百分比的原料制成：再生剂58％～70％，降粘剂28％～40％，塑化剂0.5％～2.5％，防老化剂1.5％～2.5％；所述复合温拌剂由以下质量百分比的原料制成：温拌剂50％～60％，增溶剂20％～35％，复合表面活性剂15％～30％。另外，本发明还提供了制备该温拌再生沥青的方法。本发明温拌再生沥青的三大指标明显改善，减小了老化沥青中的极性成分，减缓了再生沥青的二次老化，提高了老化沥青的低温松弛能力和高温抗剪切能力，且该温拌再生沥青路面使用性能良好。
摘要（英）：

The invention discloses warm-mixed recycled asphalt. The warm-mixed recycled asphalt is prepared from, by weight, 100 parts of aged asphalt, 8-30 parts of complex regenerant and 5-15 parts of compound warm-mixing agent. The complex regenerant is prepared from, by mass, 58-70% of regenerant, 28-40% of viscosity reducer, 0.5-2.5% of plasticizer and 1.5-2.5% of protective agent. The compound warm-mixing agent is prepared from, by mass, 50-60% of warm-mixing agent, 20-35% of solubilizer and 15-30% of compound surface activated agent. In addition, the invention further provides a method for preparing the warm-mixed recycled asphalt. Three major indexes of the warm-mixed recycled asphalt are remarkably improved, the polarity components in aged asphalt are reduced, secondary aging of recycled asphalt is decelerated, the low-temperature relaxation capacity and high-temperature anti-shearing capacity of aged asphalt are improved, and the use performance of warm-mixed recycled asphalt pavement is good.
