Bitulith widely used in pavement of highway is of the characteristic of fluidity 目前广泛应用于公路路面建设的沥青混凝土材料具有流动性大的特征。
2.
A little emulsoid was added in the bitulith to improve the performance of asphalt pavement . the new material is of rigidity and flexibility . we called it semi - rigid bituminous emulsion 乳化渣油半刚性路面材料就是针对沥青混凝土的弱点进行改性研究的一种新型复合材料，其在增加材料刚度的同时仍保留了部分粘弹性特征。
3.
The best percentages of the component parts of the new material was found in the experiments . . we measured its mechanical properties and did the test on its stableness . the results of the experiments and analysis show that the semi - rigid bituminous emulsion has advantage to the bitulith 本文对乳化渣油半刚性路面材料进行了系统的实验研究和理论分析，简述了该材料的制作和成型机理，探讨了其最佳配比，进行了稳定试验，测试了力学性能，并对其进行了微观分析。
