NCAT Offers Cold Recycle Mix Design | AsphaltPro Magazine

In , NCAT used this mix design approach for the construction of one CIR and one CCPR test section on US280 in Lee County, Alabama. Both sections have a 4-inch cold recycled layer and a 1-inch Superpave mix overlay. For the CIR mix, the foamed asphalt content was 1.8 percent and the total water content was 4.9 percent.
