In the **Guidance Catalogue for Industrial Structure Adjustment (2005 edition)**, the **Guidance Catalogue for Industrial Structure Adjustment (2007 edition) (draft for comments)**, and the **Guidance Catalogue for Industrial Structure Adjustment in Jiangsu Province** (Document No. Su Zheng Ban Fa [2006] 140), issued by the National Development and Reform Commission, the production of \"high-grade road asphalt, polymer-modified asphalt, and special asphalt\" is explicitly listed in the category of activities that are encouraged. Does modified asphalt fall under them? And which type does it belong to?
