At Black Castle Petro, we provide high-quality viscosity-graded asphalt binders classified into VG Grades (Indian Standards) and AC Grades (American Standards) to meet diverse project requirements across various climatic and traffic conditions.
VG Grades (Indian Standards):
Viscosity grading in VG grades is based on the absolute viscosity of asphalt binders at 60°C and the kinematic viscosity at 135°C.
These grades are optimized for Indian road construction standards, ensuring performance in varying climatic conditions.
Common grades include VG-10, VG-20, VG-30, and VG-40, suitable for applications ranging from light-duty roads to heavy traffic pavements.
AC Grades (American Standards):
AC grading is determined by the viscosity of asphalt binders at specific temperatures (140°F and 275°F).
These grades focus on the properties of the asphalt binder before the Hot Mix Asphalt (HMA) manufacturing process.
Common grades such as AC-10, AC-20, AC-30, and AC-40 are widely used in projects requiring precise temperature and load resistance.
Key Benefits:
Tailored Solutions:
Both VG and AC grades cater to specific standards, ensuring compatibility with regional and international paving requirements.
Quality Assurance: Black Castle Petro’s viscosity-graded binders are rigorously tested to meet the strict specifications of Indian (VG) and American (AC) standards.
Versatility: These grades support a variety of applications, including highways, urban roads, airport runways, and heavy-duty industrial pavements.
Applications:
Black Castle Petro’s VG and AC grades are designed for exceptional performance in diverse environments, offering durability, flexibility, and resistance to rutting and cracking in both hot and cold climates.
By delivering asphalt binders graded to VG (Indian Standards) and AC (American Standards), Black Castle Petro ensures superior quality and reliability for modern infrastructure projects worldwide.
