Superpave级配与AC级配路用性能对比研究

结合“六盘山地区公路修筑技术研究”课题研究工作,通过室内试验、铺筑试验路,针对上面层采用A C-16和Superpave-16两种级配设计方法所设计的沥青混合料进行了水稳定性、抗车辙性能、低温性能三方面的路用性能的对比研究;同时,按照Superpave-16级配,分别采用标准马歇尔、大型马歇尔、旋转压实三种成型方法对所设计的沥青混合料进行了水稳定性、抗车辙性能和低温性能三方面路用性能的对比研究,提出六盘山地区推荐沥青混合料级配类型、设计和成型方法.

Study on superpave gradation and AC gradation compared with pavement performance

Combining the research work of subject of "Construct technical rese arch in the highway of Liupan Mountain area",through laboratory experiments an d field tests on experimental roads,this paper did contrast research on the bit umen mixture pavement performance of water stability,resist rut performance and low-temperature performance,adopting AC-16 and Superpave-16 mixture design method.According to Superpave-16 gradation at the same time,the paper studied pavement performance of the bitumen mixture designed by three kinds of shaping methods,adopting standard Marshall separately,large-scale Marshall,and gyrat ory compactor.Finally it proposed the bitumen mixture gradation type,design an d shaping method recommended in Liupan Mt.area.
