不同开级配抗滑磨耗层(OGFC)混合料性能试验研究

EXPERIMENTAL STUDY ON THE PERFORMANCE OF DIFFERENT OPEN-GRADED ANTI-SLIP WEAR LAYERS(OGFC)MIXTURES

为研究不同开级配抗滑磨耗层(OGFC)混合料的路用性能,研究采用不同材料制备了5种不同的OGFC混合料,对5种混合料的路用性能进行相关试验研究,结果表明采用SK高粘沥青、抚顺高粘沥青和SK高粘沥青+0.3%聚丙烯腈纤维制备的OGFC混合料的各项性能均较为优良,而SBS改性沥青+0.3%聚丙烯腈纤维和TPS高粘沥青制备的混合料的部分性能达不到技术规范要求。

In order to study the paving performance of different open-graded anti-slip wear layer(OGFC)mixtures,this study conducted relevant experimental research on the performance of the 5different OGFC mixtures.The results show that the properties of OGFC mixture prepared by SK high viscous asphalt,Fushun high-viscosity asphalt,and SK high-viscosity asphalt+0.3%polyacrylonitrile fiber are superior.However,part of the performance of the mixture does not meet the technical specifications as SBS modified asphalt+0.3%polyacrylonitrile fiber and TPS high-viscosity asphalt are prepared.
