Why are exposed wedge joints considered dangerous in flexible pavement?

• A. They reduce road durability
• B. They are hazardous to traffic when the road is open
• C. They increase the risk of cracking
• D. They cause uneven wear on tires

Answer: (B)

Exposed wedge joints in flexible pavement can create a hazardous situation for traffic when the road is open. This is due to the abrupt change in pavement surface levels at the joints, which can lead to a sudden drop-off or bump. Vehicles may struggle to navigate these areas safely, especially in adverse weather conditions or when driving at higher speeds. The risk of accidents increases, as drivers may lose control while attempting to adjust to these uneven surfaces. Ensuring a smooth transition across pavement joints is essential for maintaining safety and minimizing hazards to vehicles and pedestrians alike.
