Experimental Study about Reduction of Frost-heaving in Railway roadbed which using wasted tire chips
- 발행 : 2010.06.10
초록
Cold area in korea, railway roadbed and gravel ballast was occurred frost-heaving. So during winter, track was rising and during thaw, track was sinking. In order to prevent the damage of frost-heaving, we have applied a few countermeasures which are circumfusion of calcium chloride and replacement of gravel ballast method. This countermeasures effect is feeble, not continuous and not eco-friendly. This study suggested that we use wasted tire-chips in frost-heaving area and considered appropriate new method to maintenance. This method was named "A Method of Wasted Tire-Chips Post". To prove effect of this method, we have tested in laboratory and field. The result of frost-heaving-ratio field test was decreased frost-heaving-ratio about 50% using "A Method of Wasted Tire-Chips Post".
