Anti-aging asphalt regenerant and preparation method of regenerated asphalt mixture
The invention discloses an anti-aging asphalt regenerant and a preparation method of a regenerated asphalt mixture. The anti-aging asphalt regenerant comprises a component A and a component B, the component A is prepared from the following components in parts by weight: 10 to 12 parts of base oil, 6 to 8 parts of polyaspartic acid ester and 3 to 5 parts of polyaspartic acid ester intercalation modified montmorillonite; and the component B comprises an isocyanate curing agent. According to the invention, the asparagus polyurea resin and the low-viscosity oil material are used as the asphalt regenerant, so that the viscoelasticity and rheological property of the aged asphalt can be effectively recovered, and the pavement performance of the aged asphalt is improved; and polyaspartic acid ester intercalated and modified montmorillonite is added as an anti-aging agent, so that the aging resistance of the recycled asphalt mixture can be effectively improved.
本发明公开了一种耐老化沥青再生剂及再生沥青混合料的制备方法，耐老化沥青再生剂包括A组分和B组分；以重量份计，A组分中包括：10～12份基础油分，6～8份聚天门冬氨酸酯，3～5份聚天门冬氨酸酯插层改性蒙脱石；B组分中包括异氰酸酯固化剂。本发明使用天冬聚脲树脂和低粘度油料作为沥青再生剂，可有效恢复老化沥青的粘弹性、流变性，提升其路用性能；并添加经聚天门冬氨酸酯插层改性的蒙脱石作为抗老化剂，可有效提升再生沥青混合料的耐老化性能。
