摘   要 ：為探究煤矸石粉填料改性對橡膠瀝青混合料路用性能的影響 ，采用煤矸石粉和石灰石粉兩種填料 進行橡膠瀝青混合料 ARHM - 13  (W)  的路用性能分析。采用掃描電鏡試驗和 XRF 試驗對比分析了填料的微觀特性，通過馬歇爾試驗對比最佳油石比下各填料混合料的物理力學指標 ，通過高溫車轍試驗、低溫小梁彎曲試 驗、凍融劈裂試驗，對比分析各性能指標。結果表明：煤矸石粉較石灰石粉的表面構造更加復雜，含有鱗片狀結構，比表面積更大，含有更多的 SiO2 和 Al2 O3 等活性氧化物，可作為良好的填料；煤矸石粉填料橡膠瀝青混合 料最佳油石比更大、動穩定度更高、永久變形更低，劈裂強度比提高，高溫性能和水穩定性得到提高；石灰石 粉填料橡膠瀝青混合料的彎曲勁度模量更低、極限彎拉應變更大，低溫性能相對較好；在對橡膠瀝青混合料動 穩定度 、變形 、強度 、高溫性能和水穩定性要求較高時可采用煤矸石粉作為填料，在提升瀝青混合料路用性能的同時可提高煤矸石的利用率。

Abstract：In order to investigate the influence of coal gangue powder filler modification on the road performance of rubber asphalt mixture, coal gangue powder and limestone powder were used to analyze the road performance of rubber asphalt mixture ARHM-13(W). The microscopic properties of the fillers were compared by SEM and XRF tests, the physical and mechanical indexes of the fillers were compared by Marshall test under the optimal oil stone ratio,and the performance indexes were compared by high temperature rutting test, low temperature trabecular bending test and freeze-thaw splitting test. The results show that the surface structure of coal gangue powder is more complex than that of limestone powder, containing flake structure, larger specific surface area, containing more active oxides such as SiO2 and AL2O3, which can be used as a good filler. The optimum ratio of oil stone, dynamic stability, permanent deformation, splitting strength ratio, high temperature performance and water stability of coal gangue powder filling rubber asphalt mixture are improved. The bending stiffness modulus of limestone powder filler rubber asphalt mixture is lower, the limit bending tension should be changed greatly, and the low temperature performance is relatively good. When the dynamic stability, deformation, strength, high temperature performance and water stability of rubber asphalt mixture are required, coal gangue powder can be used as filler, which can improve the road performance of asphalt mixture and improve the utilization rate of coal gangue.

Key words：coal gangue powder；rubber asphalt mixture；road performan
