What is the main objective of field inspection during aggregate base placement?

The primary objective of field inspection during aggregate base placement is to ensure compliance with project specifications. This is crucial because project specifications define the required materials, workmanship, and construction methods necessary to achieve a durable and functional base for the intended application, such as roadways, parking lots, or other structures.

Field inspection helps verify that the aggregate being used meets the specified gradation, moisture content, and compaction requirements, which are essential for the structural integrity and longevity of the base layer. Adhering to these specifications not only contributes to the quality of the finished work but also helps prevent issues such as settling, cracking, or other failures that could arise from using substandard materials or methods.

While reducing construction costs, increasing the amount of material used, and enhancing worker safety are important considerations in the construction process, they are not the main focus of field inspection. The inspection's primary aim is to uphold the standards set forth in the project's documentation to ensure a successful outcome.
