Regenerant of asphalt pavement material and construction method
The invention relates to a pavement regeneration construction method, a used regeneration agent is a grease substance, the content of aromatic cyclic hydrocarbon in the grease substance is more than 70%, and the content of aromatic cyclic hydrocarbon in saturated fatty acid and unsaturated fatty acid corresponding to fatty acid ester contained in the grease substance is more than 70%. According to the regenerant used for the asphalt pavement, the content of specific aromatic hydrocarbon rings of the regenerant, the kinematic viscosity and other properties are controlled, and the effect of optimizing the ductility recovery and regeneration capacity of regenerated asphalt is achieved. Meanwhile, proper kinematic viscosity and density are selected for the performance of the regenerant, so that the dispersity during mixing and the compatibility with asphalt phases are enhanced. The asphalt pavement regeneration method disclosed by the invention is simple and feasible in construction process, and the regenerated asphalt pavement is stable in property and meets the standard in Technical Specification for Regeneration Application of Asphalt Pavements.
本发明涉及一种路面再生的施工方法，其中使用的再生剂为油脂类物质，该油脂类物质中的芳香环烃含量在70％以上，且该油脂类物质所含脂肪酸酯对应的饱和脂肪酸和不饱和脂肪酸中，具有支化烷基侧链的比例不超过30％本发明的沥青路面使用的再生剂，通过控制再生剂特定的芳香烃环的含量，以及运动粘度等性质，达到了优化再生后的沥青的延度恢复和再生能力的效果。同时，本发明的再生剂在性能上选择合适的运动粘度和密度，来增强混合时的分散性以及与沥青相的相容性。本发明的沥青路面再生方法的施工工艺简单可行，再生后的沥青路面性质稳定，符合《沥青路面再生应用技术规范》中的标准。
