What Is Grade P-70 Bitumen?

Grade P-70 is a high-performance plastomeric bitumen modified with APP to deliver a step up in stiffness over P-40, with a lower penetration of 20–40 (0.1mm units) and a softening point of 115–135°C. This composition resists permanent deformation even under prolonged high-temperature exposure.

It’s suited to expressways, industrial pavements, and roads facing extreme traffic stress, where long-term rutting resistance and load-bearing capacity are the priority.

Tested to ASTM D5, D36, D113, and D2042 standards, Grade P-70 offers a reinforced, high-durability binder for infrastructure operating under continuous heavy loading.

    Frequently Asked Questions.

    Plastomeric Thermoplastic (P-70 Grade) is a high-performance modified bitumen formulated with plastomer polymers to deliver exceptional stiffness.

    P-70 is a high-performance plastomer-modified bitumen designed to provide exceptional stiffness, stability, and resistance to deformation under heavy traffic conditions.

    What are the main advantages of P-70 grade bitumen?

    It offers superior rutting resistance, long-term durability, and excellent load-bearing capacity, making pavements more resilient to heavy traffic.

    P-70 is ideal for highways, expressways, industrial pavements, and roads subjected to high temperatures and extreme traffic loads.

    The plastomer modification ensures P-70 maintains stiffness and resists permanent deformation even under prolonged high-temperature exposure.

    P-70 provides enhanced structural strength, reduces maintenance needs, and ensures longer-lasting pavements in heavy-load and high-temperature environments.
