FM 1 T-180 is associated with which type of Proctor Test?

FM 1 T-180 is associated with the Modified Proctor Test, which is used to determine the optimal moisture content and maximum dry density of soil or aggregate samples. This test is particularly important in construction and civil engineering as it helps ensure that the material used for constructing foundations, roads, and other structures is compacted to the appropriate level for stability and performance.

The Modified Proctor Test involves a higher energy compaction method compared to the Standard Proctor Test, which is why it is preferred for materials that are expected to bear significant loads or stress. This method uses a heavier hammer dropped from a greater height during the compaction process, yielding a denser material.

Understanding the significance of the Modified Proctor Test helps in selecting appropriate construction materials and ensuring that they meet the necessary specifications for quality and performance in earthwork and construction applications.
