Rapid Curing 70 RC70 a combination of penetration grade asphalt cement and a diluent or cutter highly rapid in its volatility making it easier to apply. Cut back RC70 is compliant with ASTM standard for cut back asphalt.
RC70 grade is used in the construction of roads and highways and
for treatment for pavements in compliance with ASTM. RC70 is also commonly used in spraying and for applications of mixing.
