What is the minimum frequency of testing when sampling density?

The minimum frequency of testing for sampling density being set at once per 2000 linear feet is specified in accordance with standard quality management systems and paving operations guidelines. This frequency allows for a balance between maintaining quality control and ensuring that the costs associated with sampling and testing remain manageable.

Sampling density at this interval is designed to provide a representative assessment of the material's quality across a substantial length, facilitating the detection of any inconsistencies or issues within the material being laid down. This approach is grounded in practices that emphasize statistical reliability while ensuring that testing remains efficient and practical, striking an appropriate balance between thoroughness and resource allocation in roadway construction and maintenance activities.

Adhering to this specified frequency helps in maintaining the integrity of the roadway and ensuring adherence to compliance norms, contributing to a stable and durable final product.
