Proof Rolling Subgrade

Proof rolling subgrade with a full dump truck is a method used in the construction industry to test the stability and strength of the subgrade, which is the layer of soil or other materials that supports the road or other construction project. The process involves using a fully loaded dump truck to drive over the subgrade in a specific pattern to test its stability. The dump truck is loaded to its maximum capacity and driven in a predetermined pattern across the subgrade. This pattern typically involves multiple passes over the same area, with the truck being driven in a different direction for each pass. As the truck drives over the subgrade, the weight of the vehicle causes any weak or unstable areas to settle and compact. This process allows the construction team to identify any areas where the subgrade is not strong enough to support the planned construction project. If weak or unstable areas are identified, additional soil, gravel, or other materials may be added to the subgrade to strengthen it and prevent future problems. Once the proof rolling process is complete and any necessary adjustments are made, construction on the project can proceed with the confidence that the subgrade is stable and strong enough to support the project.
