Question

Compaction of asphalt mixture is critical for the long-term performance of asphalt pavements. The lack of compaction during construction may lead to the following distresses except ___________

A) rutting
B) thermal cracking
C) fatigue cracking
D) raveling

Answer 1

The lack of compaction during construction of asphalt pavements can lead to various distresses, except for thermal cracking.

Step-by-step explanation:

Compaction of asphalt mixture is critical for the long-term performance of asphalt pavements. The lack of compaction during construction may lead to a number of distresses, including rutting, thermal cracking, fatigue cracking, and raveling.

However, the question asks us to identify the distresses that ARE NOT caused by lack of compaction. Therefore, the correct answer is B) thermal cracking. The distress in asphalt pavements not typically related to lack of compaction is thermal cracking, which is caused by temperature fluctuations leading to expansion and contraction of pavement materials.
