Which section addresses maximum recommended superelevation rates in the AASHTO Green Book?

• A. Sec. 3.3.3.1
• B. Sec. 3.3.3.2
• C. Sec. 3.3.4
• D. Sec. 3.2.2

Answer: (B)

The section that addresses maximum recommended superelevation rates in the AASHTO Green Book is critical for understanding roadway design and safety. Superelevation is the banking of a roadway at a curve, allowing vehicles to navigate curves safely while minimizing the risk of skidding or overturning. The correct section, which is 3.3.3.2, provides detailed guidance on the appropriate superelevation rates for various types of roads and conditions. It discusses the factors that influence the design of superelevation, such as road type, speed, and terrain. By establishing maximum recommended rates, this section helps engineers ensure that roadways are designed for optimal vehicle stability and driver comfort, which is essential for maintaining safety on the roads. The other sections mentioned, while potentially relevant to roadway design, do not specifically focus on the maximum recommended superelevation rates, making them less applicable to the question. Understanding where this information is located in the AASHTO Green Book is vital for transportation engineering professionals who are designing roads that will accommodate safe and efficient vehicle travel.
