What is the maximum tolerance of thickness for core samples compared to the design thickness?

• A. 10% of the design thickness
• B. 15% of the design thickness
• C. 20% of the design thickness
• D. 25% of the design thickness

Answer: (B)

The maximum tolerance for the thickness of core samples compared to the design thickness is established to ensure that the constructed surface meets safety, durability, and performance standards. A tolerance of 15% allows for minor variations in thickness while maintaining the overall integrity and functionality of the asphalt pavement. This standard helps accommodate potential inconsistencies in the manufacturing and laying processes without compromising the pavement’s structural and physical characteristics. By keeping the tolerance within this range, it strikes a balance between realistic construction practices and the need for maintaining quality control standards. Such specifications are commonly accepted in the industry as they ensure that deviations from the design do not adversely affect the performance of the pavement or lead to premature failure.
