1.6. Comparison Between AASHTO and USCS

Try these first

1. 1.

   What does AASHTO stand for?

   Hint

   Think about transportation authorities.

2. 2.

   What is the main focus of the USCS?

   Hint

   Consider its use in geotechnical engineering.

3. 3.

   Which classification relies on Atterberg limits?

   • AASHTO
   • USCS
   • Both

   Hint

   Remember which system is used for highways.

4. 4.

   True or False: USCS is primarily used for pavement design.

   • True
   • False

   Hint

   Consider the general context of use.

5. 5.

   Given a scenario where soil is categorized as A-2, analyze its potential impact on highway stability versus a CH categorized soil.

   Hint

   Evaluate load-bearing qualities.

6. 6.

   If AASHTO recommends a certain soil type for subgrade, and USCS identifies it as lacking low plasticity traits, what could be the engineering implications?

   Hint

   Think about how classification affects stability.
