为了研究纳米ZnO/SBS改性沥青混合料的路用性能,以AC-13为例,通过基质沥青、纳米ZnO改性沥青、SBS改性沥青与其做对比。通过车辙试验、低温弯曲试验、浸水马歇尔试验以及冻融劈裂试验,得到纳米ZnO/SBS改性沥青混合料的高温稳定性能和抗水损害性能有所提升,而低温抗裂性能表现平平,但仍能满足路面使用性能要求。 In order to study the road performance of nano-ZnO / SBS modified asphalt mixture, take AC-13 as an example, compared with matrix asphalt, nano-ZnO modified asphalt and SBS modified asphalt. Through the rutting test, low temperature bending test, immersion Marshall test and freeze-thaw splitting test, the high temperature stability and water damage resistance of nano-ZnO / SBS modified asphalt mixture are improved, while the low temperature crack resistance performance is flat, Still able to meet the road performance requirements.
