粉煤灰改性沥青胶浆的试验研究

本文探讨了用粉煤灰代替石灰石作为沥青混合料中填料的可行性,研究了不同等级的粉煤灰不同掺量时,沥青胶浆的主要技术性质及其改性作用;还研究了掺加粉煤灰的沥青胶浆与石料的粘附性能,从而归纳出粉煤灰沥青胶浆的性能及其随粉煤灰品种及掺量的变化而变化的规律,得出用粉煤灰改性沥青的可行性。

Test Research on Asphaltum Modified by Fly Ash

In this article the research is about the asphaltum's technic character and the modified: function by using the fly ash with the different sorts and different percentages.Meanwhile it is also including the conglutination between the asphaltum and the stones when the asphaltum's character is modified by the fly ash.According to those tests we will find the rule that the asphaltum's character is changing with the different sorts and different percentages,and we can obtain that the asphaltum's character modified by the fly ash is feasible.
