常温改性沥青超薄罩面在成都地区预养护试点工程中的应用研究

Application research on normal-temperature modified asphalt ultra-thin covering in pre-curing pilot project in Chengdu

结合成都青白江区同华大道(红阳路至凤凰西八路段)北侧预养护试点工程,通过目标配合比组成设计及路面性能检测,探讨常温改性沥青超薄罩面在成都地区冬季应用工艺。研究表明,常温沥青混合料可降低施工的拌和、摊铺和碾压温度,具有环保及冬季施工优势。

Combined with the project of pre-maintenance on north side of Tonghua Avenue(Hongyang Road-Fenghuang West Eighth Road)in Qingbaijiang,through the target mixing proportion design and pavement performance testing,the application of modified asphalt ultra-thin covering in winter in Chengdu is discussed.This research shows that the normal-temperature asphalt mixture can reduce the mixing,spreading and rolling temperature of the construction,which has the advantages of environmental protection and winter construction.
