Heavy Vehicle Simulator (HVS) in Ovalisation Test Analysis
The Heavy Vehicle Simulator (HVS) is a customizable device built by Dynatest to study the performance of asphalt mixes and other pavement materials at very high tire pressures and loads. A loaded wheel circulates within the machine, simulating the passage of heavy vehicles or aircraft.
With its automatic heating/cooling system, it can maintain a stable temperature throughout the test and the HVS allows for adjustment of wheel load, speed, offset, and much more. With this introduction, it is clear that the HVS can be used for a wide variety of testing procedures.
The following page discuss a study conducted with the HVS on the ovalisation test.
The Vital Connection Between Pavement Testing and Road Safety!
Neglecting pavement on roads is a costly mistake. Reconstructing a deteriorated section is far more expensive than maintaining the pavement throughout its lifespan.
But beyond the financial burden, there’s a compelling story about safety risks that arise from poor pavement conditions—a story that directly affects road owners’ pocketbooks and public safety.
Today, we delve into these fascinating safety implications and uncover why proactive pavement maintenance is not just an economic necessity but a critical component of safer roads.
New blog: Do you evaluate the Boeing Bump Index (BBI)
The Boeing Bump Index (BBI) is a parameter introduced by the Federal Aviation Administration (FAA) in the 2009 for the airport pavement roughness evaluation, specifically for runways.
But why should you care about the roughness of the runway when passengers are only there for a few minutes in comparison to the time passengers spend in their vehicles on roads?

Why do you need to measure both PCN and PCI at your airport?
Airport pavement plays a vital role in the safety of passengers and aircrafts during ground maneuvers such as taxi, take off, and landing. The ground must provide the required support and necessary friction while staying in proper condition as to not generate any foreign object debris (FOD) that could be potentially dangerous for the airplane and passengers. Even a minor inconvenience can lead to significant operational issues for both the flight and the airport, resulting in substantial financial losses or safety risks. Therefore, it is crucial to maintain the pavement in optimal condition and regularly monitor all pavement characteristics, including bearing capacity, friction, roughness, visual assessment, and more.
