What Is Grade P-40 Bitumen?

Grade P-40 is a plastomeric thermoplastic bitumen modified with Atactic Polypropylene (APP) to raise stiffness and structural stability well beyond conventional or SBS-modified grades. With a penetration of 30–50 (0.1mm units) and a high softening point of 95–115°C, it holds its shape and load-bearing capacity even under sustained heat.

This grade is built for highways, expressways, and industrial roads subjected to heavy traffic and elevated surface temperatures, where rutting resistance and structural strength matter more than flexibility.

Tested to ASTM D5, D36, D113, and D2042 standards, Grade P-40 gives contractors a high-stiffness plastomeric option for demanding, high-load infrastructure applications.

    Frequently Asked Questions.

    Plastomeric Thermoplastic Grade P-40 is a modified bitumen developed using plastomer polymers to enhance stiffness, stability, and resistance.

    P-40 is a plastomer-modified bitumen designed to provide higher stiffness, stability, and resistance to deformation compared to conventional bitumen.

    What are the key benefits of P-40 grade bitumen?

    It offers excellent rutting resistance, improved load-bearing capacity, and enhanced durability under heavy traffic and high temperatures.

    P-40 is widely used in highways, expressways, industrial roads, and pavements subjected to heavy traffic loads.

    The plastomer modification allows P-40 to maintain stiffness and stability at elevated temperatures, reducing the risk of rutting.

    P-40 provides superior structural strength and deformation resistance, making it ideal for high-load and high-temperature pavement applications.
