Which is a consequence of poor mix design?

• A. Poor Pavement Performance
• B. Improved Pavement Performance
• C. Quick Construction Schedule
• D. Lower Material Costs

Answer: (A)

A poorly designed asphalt mix disrupts the balance between aggregates, binder content, and air voids, which directly hurts how the pavement behaves under traffic and weather. If the design narrows the asphalt binder film too much or uses poorly graded aggregates, the mix becomes stiff or weak in the wrong ways, leading to rutting under heat and heavy loads, cracking in tension, and increased moisture damage. These problems accumulate, causing raveling, potholes, and premature distress, so the pavement performance declines overall.

That’s why the consequence is poor pavement performance. Statements about quicker construction or lower initial material costs don’t reliably result from a bad mix design, and improved performance would be the opposite of what a poor design causes.
