二灰碎石力学性能研究

Study on Mechanical Performance of Lime-fly Ash Stabilized Crushed Stone

随着我国公路交通的迅速发展,二灰碎石混合料以其优良的路用性能得到了较为广泛的应用。通过室内试验,对二灰稳定碎石混合料的力学性能进行研究,分析级配类型、龄期等因素对混合料力学性能的影响。试验表明,混合料的密实骨架结构可以提高其力学性能。

Following the development of highway construction,the lime-fly ash stabilized crushed stone has become widespread because of its perfect performance.Based on test,this article studies its mechanical performance,and analyses the influence of gradation type and age on the mechanical performance index.Test shows that compact-skeleton structure can increase the performance.
