路可比沥青混合料力学性能试验研究

Research on Mechanical Properties of LUCOBIT Modifier Asphalt Mixture

为验证路可比改性剂的添加能够使沥青混合料在抗变形性能、低温抗裂性能、抗车辙性能、高温稳定性等力学性能上得到全面提高,保障沥青混合料路用性能良好,以AC-13C为例,添加5%、7%、9%不等的路可比改性剂进行力学性能试验,并与SBS改性沥青做对比分析。结果表明:路可比改性添加剂使沥青混合料在上述力学性能上得到了全面提升,表现优越,甚至远远优于SBS改性沥青混合料。

To test the mechanical properties ofLUCOBIT modifiers,this paper used AC-13 C with 5%,7%or 9%LUCOBIT modifiers as an example and compared with SBS modifiers.Tests such as resistance to deformation,low-temperature cracking resistance,rutting,high temperature stability were conducted.The test results showed that the LUCOBIT modifiers are able to improve the road performance significantly,which even performed better than the SBS modified asphalt mixtures.
