Revolutionizing Asphalt Paving: New Sensor Tech Unveiled by GSSI and HAMM

Tech Apr 21, 2025

The field of asphalt paving takes a futuristic leap forward with GSSI and HAMM AG’s collaborative unveiling of the RealTime Density Scan (RDS) technology. This innovative sensor, aimed at enhancing precision and efficiency in road construction, is designed to be installed on tandem rollers, transforming the way contractors manage paving density.

Cutting-Edge Solutions in Asphalt Paving

GSSI, a leader in ground penetrating radar (GPR) systems, seeks to revolutionize the paving industry by tapping into the strengths of HAMM, a leading manufacturer of compaction equipment. The RealTime Density Scan technology promises highly accurate, real-time information to ensure optimal compaction without unnecessary passes, saving both energy and resources. According to For Construction Pros, this pioneering collaboration offers a robust, vibration-resistant solution tailored for the challenging conditions of road construction.

The Science Behind RealTime Density Scanning

Density is critical in paving, influencing the durability and longevity of roads. By integrating their sensor technology with asphalt rollers, GSSI and HAMM aim to provide continuous feedback on compaction levels, addressing an industry-wide challenge of ensuring uniform density. As DOTs emphasize the importance of compaction in road longevity, this real-time data integration marks a significant advancement over existing spot-check methods, offering a seamless solution that enhances road quality.

A Partnership for the Future

Chris Green, President of GSSI, highlights the strategic alignment with HAMM as a step towards creating an innovative ecosystem that empowers contractors to preemptively address issues before they escalate. This synergy not only leverages each company’s heritage of innovation but sets the stage for a transformative impact on paving technology.

Compaction Accuracy: A Game Changer

Dr. David Cist, GSSI’s CTO, underscores the precision challenges faced in density profiling. Traditional methods fall short of providing the continuous, comprehensive data needed for optimizing compaction to DOT standards, which can directly impact road longevity. By addressing these limitations, RealTime Density Scan offers a solution that aligns with the evolving needs of the construction industry.

Real-Time Data: Revolutionizing Road Building

The introduction of real-time monitoring into the construction workflow provides contractors with unprecedented control and accuracy, enabling timely interventions to avoid costly future repairs. With this technology, roads are not just built to last but also to function more efficiently, sealing out detrimental elements like water and salt, ensuring both performance and resilience.

Bringing an Industry Evolution

Bringing the RealTime Density Scan technology to the market represents a milestone in smart infrastructure development, providing road builders with the tools needed to enhance quality assurance and operational efficiency. As emphasized by GSSI’s leadership, continuously developing the best GPR sensors remains their mission, and the partnership with HAMM is a testimony to their commitment to industry innovation.

This advancement promises to redefine industry standards, steering towards a future where technology and construction effectively converge to meet modern infrastructure demands. Expect a new era where asphalt paving not only meets but exceeds the expectations of longevity and sustainability.
