摘要: 为了研究集料组配对聚醚型聚氨酯混合料(PPUM)性能的影响,本文采用PC-13级配,设计了PPUM的三种集料组配方案(全石灰岩(PC-1)、石灰岩+玄武岩(PC-2)及全玄武岩(PC-3)),分别评价了集料组配及热氧老化、紫外辐照、水三种环境因素对PPUM路用性能的影响,揭示了PPUM的性能演变规律并建立了性能影响预测模型。结果表明:在三种集料组配中PC-1路用性能最差,PC-3路用性能最优,PC-2路用性能较PC-3有所下降,但下降幅度不超过10%;三种集料组配的PPUM性能衰变规律相似,均表现为紫外辐照和热氧老化对PPUM的高温性能基本无影响,而对间接拉伸强度、低温性能和水稳定性影响显著,反复冻融循环对PPUM水稳定性影响显著;建立的环境因素对性能影响的预测模型具有较高的拟合精度。

Abstract: To investigate the effect of aggregate composition on the performance of polyether polyurethane mixture (PPUM), this study employed the PC-13 gradation and designed three aggregate composition schemes of PPUM (full limestone (PC-1), limestone+basalt (PC-2) and full basalt (PC-3)). The effects of aggregate composition and three environmental factors of thermal-oxidative aging, ultraviolet radiation and water on the road performance of PPUM were evaluated, respectively. The performance evolution law of PPUM was revealed and the prediction model of performance impacts was established. The results show that the road performance of PC-1 is the worst among the three aggregate compositions, and the road performance of PC-3 is the best. The road performance of PC-2 is lower than that of PC-3, but the decrease is not more than 10%. The performance decay law of PPUM with three aggregate compositions is similar, which shows that ultraviolet radiation and thermal-oxidative aging have no effect on the high temperature performance of PPUM, but have a significant effect on indirect tensile strength, low temperature performance and water stability performance. Repeated freeze-thaw cycles have a significant effect on the water stability performance of PPUM.The established prediction model of environmental factors on performance has high fitting accuracy.
