What is the purpose of ballast in Static Steel Wheeled Rollers?

Ballast in static steel-wheeled rollers is about adding extra weight to increase the pressure the roller applies to the pavement. Static rollers compact by pressing down, not by vibrating, so increasing the weight raises the contact pressure, helping the aggregates rearrange, squeeze out trapped air, and achieve higher density in asphalt or base layers. This makes compaction more effective and efficient at practical speeds. It isn’t meant for cooling the engine, increasing speed, or reducing fuel use—the ballast’s role is simply to provide additional weight for better compaction.
