How many random numbers must a technician select from a loaded truck according to ASTM?

According to ASTM standards, when sampling from a loaded truck, a technician is required to select two random numbers. This requirement ensures that the sampling process captures a representative portion of the material being delivered. By selecting two samples, the technician can better assess the consistency and quality of the Hot Mix Asphalt being tested. This practice helps in achieving a more accurate reflection of the material's properties, minimizing the risk of sampling bias, and ultimately ensuring that the final product meets the necessary specifications and standards for performance.
