RTDensity Fields Density Measurement Tech for Retrofit

AI and machine learning enable continuous feedback.
Oct. 2, 2025

Any steel drum vibratory roller can be retrofit with the RTDensity system for measuring asphalt density using AI and machine learning. The system continuously feeds density measurement to operators with a reported average error of less than 1%, according to the company.

The RTDensity system uses of accelerometers, infrared temperature sensors, and GPS technology to collect and analyze data. It also has machine learning algorithms that interpret complex vibration signals that are uninterpretable to human operators, according to the company, identifying patterns that correlate with specific density levels in the asphalt.

Sensors measure temperature, location, and vibration patterns in real-time, enabling immediate adjustments.
