【摘要】 为解决煤矸石等工业固废在公路中应用存在的问题，本文以煤矸石为主要研究对象，添加一定量的石灰和钢渣，制备石灰-钢渣-煤矸石混合料。采用均匀设计方法，设计6组煤矸石混合料配合比，测试各组混合料的7 d无侧限抗压强度、180 d抗压回弹模量和劈裂强度。利用回归分析的方法，分别得出煤矸石混合料各掺量与三项力学性能间的回归方程，并分析混合料各掺量对三项力学性能的影响。结果表明：该混合料力学性能良好，可应用于不同等级公路的路面基层。更多还原

【Abstract】 In order to solve the problems existing in the application of industrial solid waste such as coal gangue in highway, this paper takes coal gangue as the main research object, and adds a certain amount of lime and steel slag to prepare lime-steel slag-coal gangue mixture the 7 d unconfined compressive strength, 180 d compressive rebound modulus and splitting strength of six groups of coal gangue mixture were tested by uniform design method by using the method of regression analysis, it is concluded that coal gangue mixture respectively the content and the regression equation between the mechanical properties of the three, and analysis the mixture content on the mechanical behavior of the three.The results show that the mixture has good mechanical properties and can be applied to the pavement base of different grades of highway.更多还原
