Asphalt Rotary Film Oven Manufacturer China Suppliers and Factory
Looking for reliable asphalt testing solutions? Our China factory provides high-precision Lab Asphalt Rotary Film Ovens. As leading suppliers, we offer equipment that simulates short-term aging per JTG E20-2011 standards to ensure pavement durability and quality control.
The Lab Asphalt Rotary Film Oven (also known as the 85 Oven) is a high-precision instrument engineered to simulate the short-term aging process of asphalt binders. Strictly compliant with the JTG E20-2011 industry standards (T 0610-2011), this equipment is indispensable for determining mass loss and evaluating critical property changes—such as penetration, viscosity, ductility, and brittle points—of road petroleum asphalt after rotary film heating.
By subjecting asphalt samples to controlled heat and rotating airflow, the oven replicates the thermal and oxidative conditions experienced during actual mixing and paving. This enables engineers and researchers to predict long-term pavement durability, optimize binder selection, and ensure that asphalt mixtures can withstand rigorous traffic and environmental stress, thereby enhancing the longevity and safety of road infrastructure worldwide.
