Q&A

Ideal-RT Test Fixture determines the resistance to rutting (rutting tolerance) of asphalt mixtures at high temperatures. A 150mm dia. Superpave Gyratory, Marshall, or field core specimen is centered in the test fixture and positioned on the platen of an asphalt load frame capable of applying a constant load of 50 ±2.0mm/min until failure. After the specimen has been loaded to failure, the shear strength is calculated using the measured maximum load, and the Rutting Tolerance Index (RT_Index) is calculated using the shear strength value.

Product Q&A

Q: How are longer specimens extracted and the piston returned?

Specimens longer than 5in are extracted by repositioning the Adapter Ring after maximum piston travel, and the spring-loaded piston automatically returns to the start position when the release valve is opened.

Q: What is the purpose of the Ideal-RT Test Fixture?

It determines the resistance to rutting (rutting tolerance) of asphalt mixtures at high temperatures.

Q: How is the test procedure performed using the Ideal-RT Test Fixture?

A 150mm dia. Superpave Gyratory, Marshall, or field core specimen is centered in the test fixture and positioned on the platen of an asphalt load frame capable of applying a constant load of 50 ±2.0mm/min until failure, after which the shear strength is calculated using the measured maximum load and the Rutting Tolerance Index (RTIndex) is calculated using the shear strength value.

Q: What specimen size does the test fixture accommodate?

It accommodates 6in (150mm) specimens, including Superpave Gyratory, Marshall, or field core specimens.
