What is proof rolling?

🔔 Follow us and activate the bell!🔔
A proof roll is an assessment of the subgrade layer prior to installing overlying pavement layers.
In this video, you can see the proof roll inspection SPORTENG conducted at the Waverley netball courts (Glen Waverley, Victoria). When proof rolling, we use a specific weighted piece of equipment (8T single axle truck) to slowly drive up and down over the prepared surface, checking for any deflection of the surface.
This will indicate whether there are weak areas in the pavement base, that may fail during the design life of the pavement. It ensures a solid foundation of your sports field and is an essential step of the quality control through the construction phase.
