In which manual can you find axle load equivalency factors for flexible pavement?

• A. AAHSTO 1993 PDG
• B. AASHTO 1993 PDG
• C. Transportation Research Board Handbook
• D. Pavement Engineering Manual

Answer: (B)

The axle load equivalency factors for flexible pavement are found in the AASHTO 1993 Pavement Design Guide (PDG). This guide, developed by the American Association of State Highway and Transportation Officials, provides detailed methodologies for the design of flexible and rigid pavements, including how different axle loads affect pavement performance and life.

In the context of flexible pavements, the AASHTO 1993 PDG presents a framework that quantifies the effects of different axle loads through equivalency factors, facilitating the assessment of how various vehicular load configurations impact pavement durability and necessary maintenance schedules. Understanding these factors is crucial for engineers to ensure that pavement designs can adequately support expected traffic loads over their intended service life.

Other manuals and handbooks may contain useful information related to pavement design, but for axle load equivalency specifically tied to flexible pavement as per the established parameters, the AASHTO 1993 PDG is the authoritative source.
