Advanced Rolling Thin Film Oven (RTFO) – Bitumen Aging Simulation System | ASTM D2872 Compliant

Technical Product Description – Rolling Thin Film Oven (RTFO):

The Advanced Rolling Thin Film Oven (RTFO) is a precision-engineered laboratory device designed to simulate the short-term aging of asphalt binders under controlled heat and airflow, replicating the oxidation and volatilization effects experienced during mixing and laying processes. This aging simulation enables accurate measurement of viscosity, durability, and other performance indicators in accordance with international testing standards.

Built to comply with ASTM D2872, AASHTO T240, and EN 12607-1, the RTFO features a high-precision convection heating chamber that maintains uniform temperature distribution at 163°C (±0.5°C). The oven is equipped with a rotating carousel that holds up to eight standard glass sample bottles, ensuring consistent film thickness and exposure during the 85-minute test cycle.

A digital PID temperature controller, along with an integrated airflow regulator and monitoring system, ensures optimal aging conditions and reproducible results. Constructed with double-wall insulation and a corrosion-resistant stainless steel interior, the oven is engineered for durability and long-term reliability in high-throughput bitumen testing labs.

Key Features:

• Fully compliant with ASTM D2872, AASHTO T240, and EN 12607-1

• Precise temperature control up to 200°C with ±0.5°C stability

• Rotating turntable accommodates 8 glass bottles for uniform film aging

• Digital PID controller with real-time temperature and timing display

• Built-in airflow monitoring system (4000 mL/min ±200 mL/min)

• Durable stainless steel chamber with corrosion-resistant finish

• Over-temperature safety protection and user-settable alarms

• Ideal for Superpave PG binder testing and performance grading

This Rolling Thin Film Oven is an essential component of bitumen quality control and performance grading workflows, offering precise control and reliable simulation of plant mixing conditions.

Product Details:

The Standard Ductilometer, also known as a Ductility Test Apparatus or Ductimeter, is a precision instrument designed to determine the ductility of bituminous materials by measuring the distance a bitumen sample can elongate before breaking. This critical test helps assess the flexibility and adhesive properties of asphalt binders used in road construction.

Built in accordance with ASTM D113 and AASHTO T51 standards, our ductilometer features a corrosion-resistant stainless steel water bath, a smooth motorized carriage system, and a digital speed and temperature control unit for consistent and repeatable testing conditions.

Ideal for bitumen testing laboratories, research institutes, highway departments, and asphalt QC/QA labs, this ductility testing machine is trusted globally for its performance and reliability.

Key Features:

• Complies with ASTM D113 and AASHTO T51 standards

• Dual or triple specimen testing capability

• Digital temperature control (usually maintained at 25°C ± 0.5°C)

• Variable speed motorized carriage (typically 50 mm/min)

• Stainless steel water bath with thermal insulation
