Mechanical Properties of Modified Emulsified Asphalt Mixture of Coal Gasification Slag
In order to explore the influence of coal gasification slag on the road performance of emulsified asphalt mixture,60℃rutting test,15℃splitting test and water boiling test of aggregate are developed in this paper.Immersion Marshall test was conducted to study the influence of different coal gasification slag content on the performance of emulsified asphalt mixture.The research results show that after adding the mechanically ground coal gasification slag into the emulsified asphalt mixture,when the content is 20%of the emulsi-fied asphalt,the high-temperature rutting resistance is increased by 22.6,the indirect tensile performance is increased by 12%,the residual stability is increased from 64.7%to 82.9%,and the water loss resistance is improved.
