What device is used to determine the bearing capacity of subgrades and manage compaction?

The penetrometer is designed specifically to assess the bearing capacity of subgrades and to evaluate the level of compaction in the soil. This device works by measuring the resistance of soil to penetration, which helps in determining how well the ground can support structures. By inserting the penetrometer into the soil, operators can gauge the strength and stability of the subgrade, which are crucial factors in construction planning and execution.

Understanding the bearing capacity is vital for predicting how well a foundation will support the weight of the structure it is built on. Proper use of a penetrometer can lead to more informed decisions regarding soil treatment, additional compaction efforts, or the need for a different type of foundation, all of which contribute to the safety and durability of the construction project.
