寒区沥青胶浆延性研究

Research on Mortar Ductility of Asphalt for Cold Area

首次提出了沥青胶浆延度的概念 ,并测定、分析了两种寒区沥青、四种粉胶比在四个温度下的沥青胶浆延度。认为沥青胶浆延度较沥青延度更能反映沥青混合料的流变性能 ,而且胶浆延度与温度。

The concept of asphalt mortar ductility was first put forward. Two kinds of asphalt for cold area proportioned with four different mass ratios of mineral powder to mortar were tested at four different temperatures. It was considered that asphalt mortar ductility could reflect rheological properties of asphalt mixture better than ductility of asphalt, and there was better correlation between mortar ductility, temperature and proportioning mass ratio of mineral powder to mortar.
