采用旋转压实仪(SGC)成型温拌和再生混合料(WMRA)和热拌和再生混合料(HMRA),根据不同成型温度下空隙率的变化规律确定最佳成型温度,采用SGC试件的密实曲线对两者的压实特性进行对比研究。结果表明:与HMRA相比,掺Sasobit的WMRA的成型温度降低约17℃;具有更优的抗车辙能力;具有更小的密实能量指数(CEI)和更大的交通密实指数(TDI),说明WMRA具有更好的施工和易性及在开放交通后更好的抗荷载密实能力。
The optimum molding temperature was determined according to the variation law of the void ratio at different molding temperature by using the rotary compactor (SGC) molding WMCA and HMRA. The solid curve of SGC Comparing the compaction characteristics of the two. The results show that the molding temperature of Sasobit-doped WMRA is reduced by about 17 ° C compared to HMRA, with better rutting resistance, with a smaller Compact Energy Index (CEI) and a larger Traffic Density Index (TDI) WMRA has better construction workability and better anti-load densification capability after open traffic.
