Loss on Heating Test of Bitumen.

Our Services

Evaluating Volatile Loss and Short-Term Aging Behaviour of Bitumen

Loss on Heating Test of Bitumen is conducted to determine the loss in weight of bitumen when heated under specified temperature and duration conditions. This test assesses the volatility and susceptibility of bitumen to hardening due to evaporation of lighter components during heating, storage, and mixing operations. The test is essential for understanding the short-term aging characteristics of bitumen before it is used in asphalt production.

Why Loss on HeatingMatters.

Evaluates Volatility and Thermal Stability

The test indicates how much bitumen loses volatile components during heating, which directly affects binder consistency and performance.

Assesses Hardening Due to Heating

Excessive loss on heating may lead to binder hardening, increasing the risk of cracking and reduced pavement durability.

Supports Asphalt Mixing and Handling Control

Testing helps verify whether bitumen can be safely heated during mixing without excessive property degradation.

Ensures Compliance With Standards and Specifications

Loss on heating testing verifies conformity with IS standards and MoRTH specifications, enabling acceptance for road and highway construction.
