Experimental Study on the Effect of Freeze-thaw Cycles on the Deterioration of Physical Properties of Slate
In order to study the physical properties of slate as a block stone roadbed filler,this paper takes the slate in the roadbed block stone of Gonghe-Yushu(Gongyu)Expressway in Qinghai Province as the research object,and analyzes the effect of freeze-thaw cycle on its quali-ty,longitudinal wave velocity and porosity.The test results show that with the increase of freeze-thaw cycles,the mass and longitudinal wave velocity of slate samples decrease,while the porosity increases.For reference.
