What is the purpose of determining random core locations?

Determining random core locations is essential for ensuring unbiased sampling for testing. By selecting core locations randomly, it helps prevent any bias that may arise from systematic selection based on location. This randomness is vital in obtaining a representative sample of the material being tested, such as asphalt or concrete. By achieving such unbiased results, the integrity of the test data is maintained, leading to more accurate assessments of material quality. This focus on neutrality in sample selection is crucial in quality management systems to ensure that decisions are based on accurate and reliable data, which is fundamental for making improvements and meeting standards in roadway engineering and construction.
