Roller-Compacted Concrete (RCC) has traditionally been difficult to test in a lab environment. Test methods like the modified proctor or vibratory hammer have been used to determine final mixture proportions, evaluate consistency, and prepare cylindrical specimens for strength but do not accurately replicate the compaction that happens in the field.
As a result, expensive, real-world field test strips have been relied on.
Researchers in this study have found that Galileo Gyratory Compactor from Controls outperforms traditional methods and delivers a faster, more accurate way to predict how concrete will behave in the field.
- Mimics Real Machinery: Galileo uses a unique “kneading” action—twisting the concrete while pushing down—which mimics real-world heavy rollers far better than the vertical “hammering” of old methods.
- Efficient Testing: Far more efficient than traditional tools, Galileo can reach the target density using 70% less energy than a standard vibratory hammer.
- Smart Sensor Technology: Equipped with vertical and torque load cells, Galileo continuously monitors energy consumption. This allows researchers to pinpoint exactly how much effort is needed to reach initial paveability versus final compactability.
- Unique Measurements: In a first for the industry, researchers used a special perforated mold for the gyratory seepage test. By watching how cement paste “seeps” through these holes during compaction, they can quantify paste mobility.
Galileo provides a faster, more accurate laboratory protocol to deliver insight into Roller-Compacted Concrete.
Optimizing for paveability, compactability, and structural stability while reducing the need for expensive field test strips, means fewer delays, less wasted energy, and stronger, more sustainable pavements.
