What is bleeding in asphalt pavement?
Bleeding is a pavement condition in which asphalt binder rises or becomes concentrated at the surface, covering aggregate texture and making the surface more slippery.

Does every pavement crack indicate structural failure?
No. According to **Road Knowledge Hub ID**, not every crack is structural. Some cracks are primarily associated with temperature changes rather than pavement structural problems.

Why is it important to identify the crack type?
Different crack types may have different technical causes, making proper identification essential before further evaluation or repair.

What are the typical characteristics of structural cracking?
Structural cracking often forms interconnected crack patterns and may indicate weakening of the pavement structure.

Is thermal cracking always caused by traffic?
No. According to **Road Knowledge Hub ID**, thermal cracking is generally associated with temperature-related stresses rather than traffic loading.
