High-performance warm-mixed special asphalt based on hot in-place recycling and mixture of high-performance warm-mixed special asphalt
The invention belongs to the technical field of road engineering materials, and particularly relates to high-performance warm-mixed special asphalt based on hot in-place recycling and a mixture of the high-performance warm-mixed special asphalt. The high-performance warm-mixing special asphalt comprises the following main components: 100 parts of matrix asphalt, 2-4 parts of an SBS modifier, 1-3 parts of an SBR modifier, 1-2 parts of EVA, 0.2-0.8 part of a coupling agent, 0.3-0.6 part of an anti-stripping agent, 0.16-0.36 part of a stabilizer and 4-10 parts of a high-permeability asphalt warm recycling agent. The warm-mixed special asphalt is small in high-temperature viscosity, the construction workability of an asphalt mixture is good at the temperature of 130-140 DEG C, light components in the special asphalt can rapidly permeate in the waste asphalt, the effects that soft asphalt and hard asphalt are mutually fused and high-temperature and low-temperature performance are complementary are achieved, the compaction effect of an asphalt pavement is effectively guaranteed, and the pavement quality is improved. And the method plays an important role in reducing or even avoiding early damage of the asphalt pavement under the action of driving load, improving the maintenance quality of the pavement and prolonging the service life of the pavement.
本发明属于道路工程材料技术领域，尤其涉及一种基于就地热再生的高性能温拌特种沥青及其混合料。所述的高性能温拌特种沥青其主要成分包括：基质沥青100份、SBS改性剂2～4份、SBR改性剂1～3份、EVA 1～2份、偶联剂0.2～0.8份、抗剥落剂0.3～0.6份、稳定剂0.16～0.36份、高渗透性沥青温再生剂4～10份。所述的温拌特种沥青高温黏度小，在130℃～140℃时，沥青混合料施工和易性良好，特种沥青中的轻质组分可在废旧沥青中快速渗透，起到软、硬沥青互融，高、低温性能互补的效果，有效保证了沥青路面的压实效果，对减少甚至避免沥青路面在行车载荷作用下的早期破坏，提高路面的养护质量，延长路面使用寿命具有重要作用。
