Question: 1 / 400

What is the tolerance percentage for the asphalt spread rate target?

+- 3%

+- 10%

+- 6%

+- 5%

The tolerance percentage for the asphalt spread rate target is typically set at plus or minus 5%. This standard is established to ensure consistency and quality in pavement construction. A 5% tolerance allows for minor fluctuations in the amount of asphalt used during the paving process while maintaining sufficient quality and performance of the pavement.

Using a tighter tolerance, such as 3% or 6%, may result in more precision but could also lead to increased costs and difficulties in construction operations, especially in variable conditions. A 10% tolerance would be too lenient, potentially compromising the viscosity and overall integrity of the asphalt layer. Therefore, the plus or minus 5% tolerance strikes an effective balance between quality control and practical application in the field.
