What is the required recording accuracy for Wet Density?

The requirement for recording the wet density of materials is crucial in earthwork projects to ensure accuracy in material estimates and adherence to project specifications. Wet density measurements must be precise to reflect the actual conditions of the material in its current, saturated state.

Recording to the nearest 0.1 pcf (pounds per cubic foot) provides a high level of detail that is often necessary for engineering calculations, site evaluations, and quality control processes. Achieving this degree of accuracy ensures that slight variations in density, which can significantly affect the stability and compaction of the soil or other materials being used, are taken into account. This level of precision assists in conforming to construction standards and project tolerance levels, ensuring that materials meet specifications and perform adequately under load during and after construction.

Options with less precision, such as nearest whole pcf or other larger increments, may not capture crucial variations and could lead to significant errors in volume calculations or material requirements. Therefore, the requirement for wet density to be recorded to the nearest 0.1 pcf is essential for maintaining the integrity and reliability of earthwork data.
