彩色沥青及混合料的性能评价

Evaluation on the property of colorable binder and mixture

采用JTJ F40—2004《公路沥青路面施工技术规范》相应技术要求作为标准,以上海市政管理局规范对彩色沥青及混合料的性能技术要求作为标准,以SK-70沥青及混合料作为直接对比标准,对彩色沥青及混合料进行性能评价,所评价彩色沥青胶结料性能满足JTJ F40—2004中道路石油沥青70号I-4-A的技术要求,符合上海市公交专用道对胶结料技术指标要求,彩色沥青混凝土满足JTJ F40—2004对I-4-1的沥青混凝土的技术要求,与SK-70沥青混合料性能相比,车辙动稳定度稍低,但也达到了规范要求的大于1000次的要求。

In order to evaluate the property of colorable binder and mixture, the technical require ment for bitumen of ＂Technical specifications for construction of highway asphalt pavements＂ was used to evaluate colorable binder and mixture. Besides, SK-70 bitumen property was used to compare with colorable binder. It was found that colorable binder meets the bitumen technical require ment. Colorable mixtures also meet the mixtures technical requirement. Comparing with SK-70 bitumen mixtures, the colorable mixtures dynamic stability is less. But the colorable mixtures dynamic stability is high enough.
