The Marshall stability value of a bituminous mix indicates its resistance to:
Correct answer: A. Permanent deformation under applied load
- A. Permanent deformation under applied load
- B. Water absorption by the aggregate
- C. Abrasion of railway ballast particles
- D. Shrinkage cracking in cement concrete
Explanation
Marshall stability is the maximum load carried by a compacted bituminous specimen at the specified test temperature and loading rate. It is commonly related to the mix's resistance to plastic deformation.

About Transportation Engineering
Transportation engineering covers highway planning and alignment, traffic studies, road geometric design, pavement materials and flexible or rigid pavement construction. It also includes railway, airport and traffic engineering concepts such as sight distance, superelevation, signals, capacity and level of service, distinguishing pavement failure from poor geometric design.
