This study developed the pre-treatment equipment for detecting asbestos by X-ray diffraction in recycle residue of construction waste. The equipment to be scattered, and to collected fine dust in the residue was improved and evaluated. As a result, a method to collect the flyable asbestos from the residue effectively was established. In addition, it was necessary for prevention of re-flying asbestos from the residue to keep water content which was higher than 10% by water sprinkling.
